I am so sorry this has happened to you 🫂 🫂🫂🫂 life is so hard in general rn but for people to deliberately trash a place on top of stealing and violating your space and sense of safety is evil. People are rooting for you, hun, and you're in their thoughts. 🫂🫂🫂🫂
Thanks! I actually REALLY needed that. Not getting to even talk about it to people I know in the real world makes it so much harder.
Today I desperately wanted to tell Mom about it when I called her, but as I was carefully (so as to not make her as upset as me) telling her, a nurse showed up. (She is having some new medical problem). The nurses and aides never even let her say goodbye, so not only did I not get to finish, I didn’t even get the usual “I love you” that I wanted so badly.**
I just wish there was something I could do! I found a padlock and put it on the tin building. A little late, but it they can’t just hit it again. I can’t lock the shop, barn, or coffin room because of the way they are constructed. I can’t secure things to stop thieves from just walking right in.
While I can’t put in a fence, I did dig out the wide gates we had back when we did put a fence up (to keep roaming dogs from killing our cats after a slaughter). It’s almost hilarious to have this gate there. On one side there is nothing to fasten it to, so it’s propped on the A-frame and dead car on one side and the other door of the gate it against a bit of old fence that’s only waist high. And both gates had the bottom beam break when I tried to get them free of decades of vines, so they are sort of wobbly looking. BUT they will serve as a tiny psychological barrier and, better maybe, if they try to go through or around they are likely to make a lot more noise. Maybe this time my dogs will be startled into making a fuss! ***
It’s not enough. I don’t know what would be enough. I get attached to things, especially things that were always there like a fiberglass mold I played in as a child or that clock that sat on the mantle. ****
Like, there has been a row of rocks atop one of the industrial fans. Pop put those “interesting” rocks there as he found them, over twenty years ago, and when I found them knocked off I got really upset and was desperately trying to find them in the grass so I could put them exactly like they were before.
Heck, some of the tools even had a name, like “Hugh” the bush ax. We never said “Get the bush ax”, we’d say “Get Hugh”.
I keep finding more things that were taken or wrecked. It’s draining for me, each time being hit by pain. Today I needed a hammer to do a little repair on Ryoga’s and, damn it, the hammer had been stolen. I’m probably going to be running into stuff for a long time, especially since I didn’t know where everything was to begin with.
**sigh**
I get stealing money or things of value, but with these it seems so random! The stole a “No smoking” sign! They stole a hoe but not the two foot long wrench or post hole digger beside it. They stole the handle for a small socket wrench out of the box but left all the fittings for it. They took a box with a drill and a vice grip, but left them on the ground. They didn’t take that clock I mentioned but smashed the glass and threw it in the bushes where it filled with rain water. They found a box of grandma’s jewelry(I didn’t realize it was out there*****), but while they likely stole something off the top, they didn’t even move anything below or just take the whole box.
I swear, I will always prefer venomous snakes to humans. At least I would always understand why a snake is biting me AND how to avoid it happening again! With people like this….
**Since today I spent the morning cleaning out Ryoga’s place, it may be so awful the call ended up short. My lungs feel like they are full of glue (despite the respirator I had on) and one of my eyes (despite the goggles) had a big ol’ glob of dust hurting it. Reading would have been a bit rough! Yesterday we finished Thief of Time , and today we were going to start Pyramids in out random Pratchett marathon. I’d hate to struggle through the beginning with all it’s new characters…
***Pest barks every time a leaf falls. If he’s awake he barks constantly. Since they had to walk by the dogs, most likely several times, hauling their stealings, I have to assume he was asleep. He does sleep damn soundly, maybe exhausted from always barking! LOL
****The fact I was the one that moved so much of this stuff out there after the floor collapsed in the house makes it worse. I had to put it somewhere, and honestly it all seemed safer there than the house in town. I never thought anyone would risk going out there. Heck, since that bookcase fell over I haven’t gone far into the tin building because it isn’t safe. Is it terrible I wish the other bookcase had fallen on these folks??
***** I’m not as upset about the jewelry as you would expect. No one in my family ever had much in the way gold or jewels. And absolutely not diamonds! Our jewelry may have a LOT of sentimental value, but others would call it “junk”. I know whatever they took wasn’t worth much money, and since I hadn’t really seen this stuff, it didn’t have the personal connection to me that things like Hugh had.
DTH Drilling Solutions and Types of Down-the-Hole Drills
Down-the-hole (DTH) drilling solutions have emerged as a game-changer in modern drilling technologies, revolutionizing how various industries extract valuable resources from the Earth. These ingenious tools are designed to provide efficient and cost-effective dth drilling solutions across diverse applications. This blog post will explore the different types of DTH drills and how they cater to specific drilling needs.
Conventional DTH Drills:
Conventional Down the hole drills are the foundation of down-the-hole drilling technology. They consist of a hammer and bit assembly, where the hammer delivers powerful percussive forces to the bit while air circulates to clear debris from the hole. These drills are known for their simplicity, ruggedness, and ability to penetrate various rock formations. They find mining, quarrying, construction, and water well drilling applications.
Reverse Circulation (RC) DTH Drills:
RC DTH drills address the challenges of collecting accurate geological samples while drilling. They incorporate a dual-wall drill string that enables the collection of rock cuttings through a separate inner tube, preventing contamination. This design facilitates better analysis of subsurface formations and is widely used in mineral exploration and geotechnical investigations.
Oilfield DTH Drills:
In the oil and gas industry, DTH drilling solutions have been adapted to suit the specific demands of offshore and onshore exploration. Oilfield DTH drills are engineered to withstand harsh environments, high pressures, and challenging drilling conditions. These drills are crucial in wellbore construction, geothermal drilling, and other energy-related applications.
Symmetric and Eccentric DTH Drills:
Symmetric and eccentric DTH drills are specialized variations of conventional DTH drills. Symmetric designs ensure balanced wear on the bit's face, providing uniform drilling performance. On the other hand, eccentric designs intentionally create uneven bit wear, leading to faster penetration rates in certain rock formations. The choice between these two designs depends on the specific geological characteristics of the drilling site.
High-Frequency DTH Drills:
High-frequency DTH drills utilize advanced technology to deliver rapid and efficient drilling. By increasing the impact frequency, these drills can achieve faster penetration rates while maintaining bit longevity. High-frequency DTH drills are commonly used in large-scale mining operations where productivity is a top priority.
Auger DTH Drills:
Auger Down the Hole drills combine the principles of DTH drilling with auger systems. They are ideal for drilling in loose or unconsolidated soil conditions, such as sandy or clayey terrains. The auger attachment aids in removing drilled material, while the DTH hammer provides the necessary impact force. Auger DTH drills are frequently employed in environmental and geotechnical drilling.
Compact DTH Drills:
In scenarios where limited space is a challenge, compact DTH drills come to the rescue. These drills are designed to be highly maneuverable and can access tight spaces without compromising drilling efficiency. Their versatility makes them suitable for urban construction projects, infrastructure development, and tunneling operations.
Innovation in DTH drilling solutions is a testament to human ingenuity and the constant quest
for improvement. As industries evolve and new challenges arise, engineers and manufacturers will likely develop even more specialized DTH drill types to address these demands. These might include drills optimized for deep-sea exploration, drills that integrate real-time data analytics for on-the-fly adjustments, and eco-friendly drills with reduced environmental impact.
The journey of the Down the Hole drill is far from over, and the ongoing pursuit of enhanced performance, efficiency, and sustainability promises an exciting future for the field and the industries it serves.
Conclusion
The world of down-the-hole drilling solutions is diverse and dynamic, with various DTH drill types catering to specific drilling needs across industries. From conventional drills that power through rock formations to specialized designs for accurate sample collection and oilfield exploration, the evolution of DTH technology has transformed how we tap into the Earth's resources. As technology advances, we expect further innovations in DTH drilling solutions, contributing to more efficient and sustainable resource extraction processes.
I want to know more about your baseball guys and friends and my questions:
Who has the most drip? The least?
What are they all studying in college?
When it comes to baseball, who’s the most traditional and who’s the most radical?
What pitches do the pitchers throw?
i'm so glad you like them! they're my best friends and i love answering questions about them.
this is about to be 80000000 words sorry
Who has the most drip? The least?
Ramón definitely has the most drip on and off the field. hallmarks of his style are bright colors, jewelry (earrings and a gold chain at the very least) and shirts that are unbuttoned so low it would honestly just be better to take it off altogether. it's a little unclear whether his style is actually good or whether his confidence is just so unreal that he can pull off anything. uni wise, it mostly comes down to wearing his pants as tight as possible. he's also a dirty mids believer
jake and ellie are always pretty put together but in a more understated way than ramón. charlie can dress up but usually he's just a guy i hate to break it to you. sam and tyler have likely never worn anything that wasn't team-issued or given away for free at other events.
What are they all studying in college?
tyler - mechanical engineering!
ellie - journalism
sam - business bro in some capacity. not finance or accounting but probably management
jake - doing the whole "what do you want to do with your sociology degree" "hit bombs, probably" routine
charlie - some kind of liberal arts because my soul dies every time i see some player say that they majored in something that's definitely not real like "american studies" or “science, technology & society” what do those words MEAN. in all honesty, i don't know how to classify exactly what charlie does, so if you have any suggestions, i'm all ears
ramón - media studies. he's absolutely becoming an analyst once he's done playing because he has the perfect personality for it. he and jake actually have a locker room show (like 96 questions) where they just dick around and try to corner their teammates it's delightful
When it comes to baseball, who’s the most traditional and who’s the most radical?
Charlie is definitely the most traditional. He knows the game has changed over the years, but he's so steeped in the tradition and the history and the heritage of the game and doesn't want to get too far removed from that. he's an absolute workhorse, and wants to throw a complete game every time. he's also good enough and stubborn enough that he could bring back the era of 30 complete games and 200+ innings a year (and he's trying to). his actual motion isn't that complicated either, it's a pretty simple rock step motion kind of like noah syndergaard? he doesn't mess with funky arm slots or deliveries because his pitches are just that dependable, and if you layer his different pitch deliveries on top of each other, they're pretty indistinguishable
on the other end, ramón doesn't mind messing around in the pitching lab working on the next new thing. if there's a new drill/tool/program he's willing to give it a shot, no matter how far out it is. their approaches make them butt heads sometimes but they really balance each other out. ramón does not have a uniform arm slot - he's a sidearm pitcher but just kind of flings the ball out there and hopes his catcher finds it. because of this, he's a little wilder but it's worked for him so far.
whenever i think of them, strictly in a baseball approach sense, i think of this article about gerrit cole and trevor bauer, except for. you know. charlie and ramón actually like each other and ramón is a much better person than bauer.
What pitches do the pitchers throw?
Again, charlie is really really traditional. He probably has a four or five pitch mix, and relies mostly on his blistering four seam fastball and slider, followed by his changeup and splitfinger. maybe a stomach-dropping hammer curve if he wants to mix it up. he throws very hard and very accurately, so he's never really had to learn to fool hitters. he doesn't tip pitches but you basically know what you're getting and it still doesn't help.
ramón does not nearly have the velo charlie does. it's not his style of pitching anyway — he relies mostly on offspeed stuff, lots of motion and getting hitters to chase out of the zone, because let's be real he's not throwing in the zone anyway. i also think he has a bigger arsenal, but it's not that consistent, he'll just mix in and out depending on what's working. he likes a cutter and slurve, and was early on the sweeper bandwagon. he does have a fastball (he prefers two seam) but it's nothing groundbreaking. he's also actively working on a circle changeup

That's where Down-the-Hole (DTH) drill bits come into play, offering a game-changing solution for drilling through tough materials with precision and speed. Let's take a closer look at how DTH drill bits are revolutionizing the industry.
Understanding the Technology:
AG-DRILLs DTH drill bits are like the rock stars of the drilling world, working alongside DTH hammers to penetrate rocks, soil, and more. Unlike traditional methods, where the hammer is at the end of the drill string, DTH drilling flips the script, placing the hammer behind the drill bit. This tweak in design packs a punch, delivering better energy transfer and faster, straighter drilling.
How They Work:
Picture this: compressed air or fluids pumped down the drill string actuate the piston inside the hammer, which then hammers away at the back of the drill bit. It's this constant percussion action that pulverizes rock formations, making way for efficient drilling, no matter how challenging the conditions.
Advantages That Matter:
DTH drill bits aren't just another tool in the box; they're the MVPs of drilling operations. Their versatility shines through in various formations, from hard rocks to soft soils, ensuring consistent performance across the board. Plus, they're not picky about angles or depths, making them a go-to choice for everything from mining to construction projects.
Speed and Precision:
Speed demons, rejoice! DTH drill bits boast impressive penetration rates, meaning projects get done quicker and with fewer headaches. And let's talk precision – maintaining hole straightness is a breeze with DTH drilling, perfect for those projects where accuracy is non-negotiable.
Built to Last:
When it comes to durability, DTH drill bits are in it for the long haul. Crafted from top-notch materials like tungsten carbide and hardened steel, these bad boys can take a beating and keep on drilling. That means fewer replacements, less downtime, and more money saved in the long run.
Environmental Friendliness:
But it's not all about performance – DTH drill bits also have a softer side. Their efficient drilling process means less disruption to the environment, making cleanup a breeze once the project's done. Plus, they're quieter and produce fewer vibrations, making them a neighbor-friendly option for urban drilling projects.
In Conclusion:
In a world where time is money, DTH drill bits are the ultimate investment. Their unmatched efficiency, precision, and durability make them a staple in mining, construction, and beyond. As technology continues to advance, expect DTH drilling to lead the charge, driving progress and productivity in drilling operations worldwide.

Top Hammer: Ideal Selection for Mining and Underground Operations
Let us first understand the importance of top hammer drilling for diverse purposes of mining and construction. Well, top hammer drills make the best use for drilling short and narrow boreholes in hard rock. The percussive system is responsible for generating a percussive force on the drill rods or bits, which make it possible for the professionals to drill holes in the hard rock and it continues in a combination of drill and rotation; like, if the percussive system drills the rod for 2,000 to 5,000 minutes, the rotation speed can be examined at 60-200/minute. Besides, drilling through a top hammer can be considered the default choice for all holes with a width between 1- 1/2 -4in and a depth of about 30m.
For a very long time, the equipment has been using mainly for mining, quarrying for rock material, and construction. The combination of “drill and blast” method through the drilling turn the entire excavation process an easy task.
The reason why the top hammer method is widely preferred worldwide is because of its feature of using water to flush out cuttings. Due to this characteristic, the hammer makes the best selection for underground mining operations. It improves the underground work environment simply by lessening the bearing of drilling dust air in the number. It offers more accurate and controlled blasting which is highly critical in underground operations. It is also an ideal choice for bolting operations in that it secures tunnels; however, the machine used can be slightly different and require the same skillset from operators.
Besides all the applications mentioned above, the hammer is considered for a special use in tunnel forepoling that refers to weak ground conditions and a necessity for using top hammer methodology.
The Limitations of Top Hammer:
Unlike many other tools, the top hammer also comes up with a set of drawbacks and limitations. One of the biggest drawbacks is seen when the drill string loses percussion energy, longer rods start lessening the energy and the efficiency of both. The speed keeps decreasing towards the end of longer holes. Constant shock waves on couplings and rods of top drill strings create continuous wear on various components, which means more consumables.
A Brief Understanding Of Different Drilling Machines
Drilling and extraction are fundamental processes in the oil and gas industry. Drilling machines come in different shapes and sizes, each with specific features and benefits. A deep hole drilling machine is a type of machine used for drilling holes that are deeper than those that can be drilled by a standard drill bit.
Deep-hole drilling machines come in various designs, but they all share some essential parts and features. These include a drill bit, a chuck to hold the drill bit, a spindle to rotate the drill bit, and a feed mechanism to move the drill bit into the work piece.
Standard Gun Drilling Machines
The most common kind of drilling machine is the gun drilling machine. Gun drilling machines use rotary hammers to create a hole in a rock or other material. They come in several sizes and speeds, but all share some common features.
First, all gun drilling machines have a rotating drill bit that sits at the top of a long barrel. The drill bit is attached to a motor that spins it quickly around the barrel. This movement creates a circular pattern of holes in the material.
Second, all gun drilling machines have an operator control panel at the front of the machine. This panel contains buttons to control the drill bit's speed and direction. It also has indicators showing how deep the drill bit is cutting into the material.
Finally, all gun drilling machines have a hammer that hits the drill bit repeatedly as it rotates. This action creates sparks that break down large pieces of rock into smaller ones. As a result, gun drilling machines are versatile tools that can be used for many different tasks, including mining and construction.
Micro Gun Drilling Machines
Micro gun drilling machines use a rotating drill bit similar to a gun. The drill bit moves up and down, making it easy to create small holes in a variety of materials. They come in various sizes and are used for a variety of applications, including the production of parts for products such as electronics and automobiles.
Universal Gun Drilling Machines
Universal drilling machines are a great choice for anyone looking to drill holes into a variety of materials. They are versatile, efficient, and can handle a wide range of drilling tasks.
Some of the most common Universal drilling machines have a quick change gear system that allows users to quickly switch between different drilling modes and variable speed control that lets users adjust the speed according to their needs. Additionally, these machines have power augers that help make hole formation more consistent and accurate.
BTA Drilling Machine
A BTA machine is a specific kind of deep-hole drilling machine crafted and developed to optimise the BTA and related tooling performance to make huge and deep holes in virtually any material. It is widely used worldwide, including in North America, South America, Africa, the Middle East and Asia. BTA drilling machines have the following advantages: high productivity, low cost and high reliability.
Skiving and Roller Burnishing Machines
Skiving machines create smooth surface edges by shaving off material with a sharp blade. Roller burnishing machines use rolls of pressure-sensitive paper to create a highly polished finish on surfaces. Both machines can use several materials, including metals, plastics, and composites.
Whether it is BTA deep-hole drilling or any other kind of deep-hole drilling, WIDMA provides the best machining solutions to different industries, resulting in the overall development of the metal industry.
Brief introduction of drilling rigs and its current situation for self-drilling anchor bolt
In the geotechnical anchoring industry, drilling rigs are important construction tools. Here we will learn about rock drilling rigs.
Introduction:
The term “drill rig” in the geotechnical anchorage industry refers to drilling rig that drills into the rock. According to different rock breaking methods, it is divided into three types: percussive drill rig, roller drill rig, and cutting drill rig.
Percussive drill rig
Percussive drilling rig is one that mainly impacts on the rock, supplemented by rotary motion, and at the same time applies a certain axial force to break rock. Percussive drills are also often called rock drilling machines. According to the position of impact action, it is divided into DTH type and top hammer type.
DTH drilling rig refers to the drilling rig with DTH impactor at the bottom of the drill rod. The piston in the impactor directly impacts the drill bit while applying a certain axial force to break the rock.
Top hammer drilling rig refers to one where the impactor is on the top of the drill rod. The piston in the impactor impacts the drill pipe. The shock wave is transmitted to the drill bit through the drill pipe, and a certain axial force is applied to break the rock at the same time. For example air-leg rock drills, outrigger hydraulic rock drills, hydraulic rock drill rigs, etc.
Roller drill rig
The drilling rig takes rotation as the main function, and impact as the auxiliary function, and at the same time applies a large axial pressure to break the rock. For example, mining roller rigs, oil rigs and so on.
Cutting drill rig
The drilling rig is mainly used for rotary cutting, while applying a small shaft pressure to break the rock. For example, rotary drilling rigs, geological core drilling rigs, etc.
The current situation of drill rig for self-drilling anchor bolt:
Self-drilling anchor bolt technology originated from foreign countries, and its application in foreign countries is relatively mature. Air-leg rock drill rigs, hydraulic rock drill rigs and other top hammer drill rigs are mostly used. In domestic construction, the application of self-drilling anchor bolts is in its initial stage.
At present, the main drilling equipment is to refit the down-the-hole drilling rigs. Usually, a drill tail bushing is installed between the drilling rig impactor and the hollow bar for transition. Although it can also meet the drilling needs, the construction efficiency is low. During the construction of the Zhengzhou-Wanzhou High-speed Railway, a three-arm rock drilling rig was used to drill the self-drilling bolts of KELLEG, which greatly improved the construction efficiency. Therefore, if self drilling anchor bolt technology is to be better promoted and applied in China, the drilling rig needs to be continuously optimized and improved.
So these first few weeks of the brief are going to be focusing more on working - doing tasks, such as ceramics.
For today, we were split up into two groups, where the following are groups that start in the morning:
Group a-j = Wood work
Group k-v = Ceramics
I was in ceramics, so without waiting around, I and my peers went to the ceramics workshop to get started.
Like we did during on the 6th where we worked with stone-based clay to create golems, we did the same; further developing our dioramas. We were going to do whilst using a new type of clay that is earth-based; terracotta.
We had to focus on creating at least one building, as well as several different environmental things such as stones, rocks and vegetation.
For the building I created a kind of gazebo, meant to match the ethereal look of the unicorn.
I was actually inspired by a build I recently had done on the game Sims 4, shown below:
So I began by rolling out some of the basic shapes that I needed for the building, including columns and some circles to make up the base. This proved to be quite difficult, since I and my classmates beside me found that terracotta is surprisingly soft in comparison with stone-based clay.
Now that I have all the basic structural parts made, it was time to assemble them all using slip. This was a slow process, since the medium is still very soft.
Eventually, I managed to put everything together, despite it being quite “flimsy”:
I also created some rocks and pebbles to go along with the rest:
Afternoon:
As mentioned in the beginning of this post, the morning was focused on doing ceramics, which means that it was time to do the wood workshop.
I have some experience with working with this medium as well as using most of the tools that are most often used for woodwork, despite it being a while ago now.
As with ceramics, we were firstly told the basic safety precautions that we have to keep in mind while being in the workshop. After this, we were then introduced to all the different machinery, materials and techniques that we were most likely going to use;
After this, we were then told to begin putting together some kind of figure, creature or character of some sort. I decided to go with a (draft) horse:
I gathered a bunch of different pieces of scrap wood in different lengths and thicknesses, and proceeded by sketching out the different parts such as the body, legs, neck, tail etc.
I then went to one of the machines to cut out the basic shapes, making sure to keep it even so they would come together nicely. Now, with all the parts laid out, it was time to put it all together! For this, we were going to use a technique in which you drill a hole and push/bang a pin into it. To make sure I do this correctly, I mark each bit with a pencil.
I used a drill for this part, making sure to drill it as straight as possible. The pins would then get beaten into the holes using a mallet. Some of the wood is quite soft, so using a hammer would only damage it.
So with the holes drilled, this is how it looks so far:
I am yet to put together the more intricate bits such as the legs and tail. I was thinking of using wire and a smaller drill head, since I still want the legs to be moveable, so I can have it move more realistically when or if I use it for some stop motion animation.
Below is a picture i took showing some of my peers work; (or what they managed to get done during that lesson)
Update:
So since I didn’t manage to finish my horse figure during the lesson, so I took all the little bits back home to try and finalise it.
So I knew that I needed the legs to be posable, a.k.a. able to move. I didn't really have any wire, so I had to scratch my previous idea. I asked a friend for some advice and help, and we came to the conclusion that the best thing would be to use nails; they’re small so they won't look too obvious.
Another, maybe even more important, reason for using nails is that I can drill a hole before hammering in the nails, hereby hopefully that would reassure that the wood wouldn't split.
I went back and forth a few times, trying to decide what size to go for the drill. I was aware that I needed it to be big enough to be able (nails) to get hammered in, but not so big that it would be too loose.
Below is me comparing the size of the drill head and the nail.
–But eventually we settled on going small (1 mm.), our train of thought was that you always can go bigger if needed.
I also made sure to mark where I wanted to drill through the bits of wood, using a red pen to distinguish between the old markings and new ones.
The next step was to attempt to drill through the wood pieces. I had already labeled each bit which proved to make everything a lot easier.
I knew I wanted to have the legs go “inward”, as shown below:
I then clamped the pieces together to make sure it was in the right place and then, I drilled through the two pieces of wood:
After this was done, we moved it to a bigger and stronger clamp, clamping it down to the worktable so we could hammer the nail in. We made sure to have the now drilled holes completely lined up by inserting the drill head through the wood pieces as we moved it around without the clamp securing them together.

We ran into a problem with the nails being too long; if we just hammered them in as they were, they would poke through. To avoid this, we shortened them by cutting off a little bit, repeating this for four nails.
To ensure that the nails would go in smoothly we wanted to sharpen the ends by sanding them down a little. We first replaced the drill head with a small sanding head. The outcome was acceptable, but it was quite difficult and a bit time consuming:

So we then switched that out with a more rough sanding head, which proved to be much easier:

With the nails now the right length and “sharpened”, we could hammer it into the hole we had drilled from earlier. Here is the outcome of that:
I was very pleased with how it turned out; the nail now sits securely and doesn't poke out on the other side– (between the figures legs), which is yet another plus. But on top of all that, it’s a tight fit (yet you can still move them around) which is great, because the last thing I would have wanted was it to be too loose and sort of just... fall apart.
We then did the exact same thing with the other back leg; marking → clamping → drilling → re-clamping → hammering
;And with that all done, the horse now has back legs!
At this point, we decided to do the front legs separate from the body, and then nailing them to the figures body afterwards. This allowed us to work more freely, not being restricted by the rest of the horse.
And with the front legs now nailed to the body, the base of the figure is finally finished! Below is a little video showing it off:

I could have left it at that, but I wanted to experiment a little more by taking it a little further. So I gathered a bunch of scrap supplies; random things like cables (to strip and extract the copper wire from), old fabrics, beads, different kinds of string etc.
I found that I had a few different wires to choose from as the cables had some different ones hidden in them;
I sketched out some ideas, sort of brainstorming the possibilities;
I decided to go with making some horse tack for my figure.
To begin with, I wanted to create the bridle. I based this on the bit-less bridles that some riders use;
I knew I would need to create some small loops for it, so that was the very first thing I did. I used the thinner copper wire from one of the cables I had stripped and some tools to make these;
Making the bridle (as well as the saddle) was mostly just trial and error, experimenting with the fabrics and tools I had laying in front of me. I eventually decided on using some string, tying them to the small rings;
Now it was time to move on to making the saddle. For this, I made sure to reference the basic idea from the sketch I had created earlier. The inspiration for the saddle was based on cowboys in the 18th hundred.
So I took some corduroy fabric from some old corduroy pants that my friend allowed me to use for this. I kept going back and forth between drawing guidelines and trying to see how it would fit on the figure, adjusting as I went.
Here is a picture of the saddle cut out + a saddle pad. I didn't take that many pictures of this, but I basically made some stirrups using the thicker copper wire, attaching them to the saddle.
I had now finished the base of the tack for my figure. Next, I wanted to try and colour the horse. I wanted to use gouache paint to get a matte look to it, hopefully making the tack stand out from the horse a little more.
I started blocking in the colours, trying to make textured gradients by dabbing on the paint with my brush. I also made sure that I moved around the limbs to paint all the areas hiding in certain poses.
Skipping ahead a few pictures since it is quite repetitive from this point on, I decided to add hair to the horse. I did this by using normal wool and a comb, brushing it out until It had the desired feel I was looking for. Using a glue gun, I attached it in layers bit by bit:
I styled it a little by braiding it and positioning it where I though fitted best.
I repeated this same technique with the tail, then styling it by trimming bits away to shape it a little more:
And with everything done (the figure itself, horse tack now finalised completely also able to be taken off if wanted, “paint job”, hair) this is the result!:
