  1. A heavy day forging....

    Ok, so I didn't get more video. I got on a roll and the GoPro wasn't in the shop. It got drawn to 2-1/4" square, then the section to be twisted was octagoned, and into Screwcifer it went! Drawn out to ~1.75"x1.625"x23" The untwisted ends were trimmed, and onto the surface grinder to get cleaned up. Came out to 1.695"x1.365"x19". Customer spec was for 1.5"x1.25"x16", but they're fine rough machining it down. And a bit of a closeup. The 3 colors of steel in this one are going to make it look really nice. Also, once the customer's final machining is done, it will be a good bit more narrow, so there should be a good bit more of the fun bits on the inside. The other size needed for this order is a slab 1"x5"x10.5". Here's a picture of the matching slab to go with this bar. It gives a better idea of the color contrast this steel mix gives. Ignore the big funky looking smudge across this billet, that's just a remnant from where I used paracord to hang it in the etching tank. (Note: This picture was taken with a flash, but it shows the color contrast much better)

    Owen, The press is around 45ton and it seems to handle it fine. Or did you mean a twisting rig?
  3. A heavy day forging....

    Thanks folks! I'll hopefully have more more video of 2-1/2" square being twisted at a slightly increased speed soon.
  4. A heavy day forging....

    The motivation behind Screwcifer is a 2HP motor spinning a large triple reduction gear reducer. It's built to twist up to 3" square and still have a reasonable safety margin. So far I haven't worried about cooling the ends, though I may with this billet since I may take the ends to 2" square to save a little on waste and keep me from having to build another set of dies right now. It depends a bit on what bits of steel I find around the shop tomorrow that I can hack a tailstock die together from. Here's a video of the second twist I did with it. First was 1" square, this was 2".
  5. A heavy day forging....

    This size is half of the contract, I've got another that finishes to ~15lbs ea that I need to do 50 of as well. In all reality, it will be 6-12 months of work. One piece is random, the other is a twist (but I'm randoming the stock some before twisting to make it a little more interesting).
  6. A heavy day forging....

    So, I have a really large pattern welding contract coming up, and I'm working on the final prototype pieces. This set a new record for me today, so I figured sharing would be as good as excuse as any to return to one of the forums that I've neglected for way too long. I can't say what the end product is yet, but trust me, as soon as I can, I will. Today's work was a billet of 1045/1075/15n20. Just a wee tiny thing, it started at 2"x4-3/4"x10" (about 30lbs). This is to date the largest billet I've ever done, and provided that everything works out, I'll only have to do somewhere between 25 and 50 more of them! After the first weld/draw it was down to 3"x1-1/2"x~21" usable That was cut, ground, and re-stacked by 3 for 75 layers and drawn to 2-1/4"x2-3/4"x~13" usable Tomorrow I'll cut, grind, and re-stack this by 2 once more for 150 layers. Then, it will get drawn to 2-1/2" square and get the living bejeezus twisted out of it on the twisting machine I finished building not long ago, dubbed "Screwcifer". Here's a little video of the first "real" test twisting a 2" square billet. screwcifer_first_twist_2_inch.lrv I'm gonna go find some Advil....
  7. "Basket Case" Pattern Welded BIllet - .105"x1.625"x11" $140 Stock #: 20181017-BasketCase1 This is a .105"x1.625"x11" billet of 1084/15n20/Ni steel my "Basket Case" pattern. The Ni alloy sheet in this begins at .0032" thick and is only microns thick after forging, so should not affect blade edges at all.
  8. "Spots and Stripes" Pattern Welded BIllet - .125"x2.25"x12.5" $175 Stock #: 20181017-SpotsAndStripes1 This is a .125"x2.25"x12.5" billet of 1095/15n20 steel in my new "Spots & Stripes" pattern. This steel has 9 alternating layers of the random "Spots" and the bold "Stripes" and should be very interesting when ground.
  9. "Pseudorandom" Pattern Welded Billet - .170"x1.25"x10.5" $115 Stock #: 20181017-Random2 This is a .170"x1.25"x10.5" billet of 1084/15n20 steel in a "Pseudorandom" pattern.

  12. Hey all, I know I haven't been around in a while, but it's been crazy here in Dekerville as the shop has been undergoing MASSIVE changes. Change isn't free though, and so I have a bunch of barstock here available for sale. There will be more coming, and I'm also always up for custom orders if you need something special. My shop capabilities have changed dramatically, and so I can now work much larger stock than before, and am doing surface grinding in house now. Feel free to call on me for large projects as I can handle billets up to ~30lbs now. All of my steel comes to you normalized, annealed, and precision ground unless otherwise noted. Note that the etch on this piece is simply to show an idea of the pattern. Contrast should be more pronounced after heat treatment and finishing. Shipping is via USPS flat rate box, and I'm happy to combine multiple orders into one shipment. You pay the shipping, I'll pay the insurance. On to the show! I'll add additional posts to this thread for each available piece. "Pseudorandom" Pattern Welded Steel Billet - .190"x1.25"x14" $165 Stock #: 20181017-Random1 This is a .190"x1.25"x14" billet of 1084/15n20 steel in a "Pseudorandom" pattern.
  13. New monster forge build

    Still waiting on the metalwork to be completed, but that's no reason to not work on the new forge! Yesterday I began casting the floor. The design calls for the floor to be cast on a separate plate that will simply sit in an angle iron frame. The floor will be composed of about 3/4" of Mizzou castable for the bottom layer (I already had it sitting around) and topped with 1/4-1/2" of Greencast 94. I had originally intended to lay hard firebrick for the base and cast a layer of Greencast on top of that, but then I had a couple of realizations/discoveries. First off, I'd have no good way to hold the brick in place so it wouldn't slide off the plate when moved. Second, Mizzou, and Greencast, and probably every other castable, has a 1 year shelf life. I was already past that on the Mizzou, so it was time to use it. So, today I prepped the plate and cast the floor. I wanted to make sure that the refractory would have something to grab onto, so first I laid out a grid on the plate (hooray for Dykem in a spray can!). Then I drilled 16 evenly spaced 1/4" holes in the plate and filled them with 1" long 1/4-20 bolts. After that, I screwed nuts onto the bolts, but only until they were fully engaged. The thought is that this will give the castable something to hold onto, but when it's time to re-cast the floor I'm hoping I can just unthread the bolts from underneath and pop the old casting off. We'll see how that goes I set the prepped plate on top of s couple of garbage bags and folded the extra in before building a casting form out of 2x4s. Then, the bag ends were flipped back up and secured with tape to the form so they wouldn't sag. After that, I mixed up the Mizzou to cast. 50lbs calls for 5 pints (80oz) of water. That equates to 2 Gatorades and a smidgen less than 1 bottle of water. Mix well and cast. It's not something that "pours". According to the Harbison Walker sales rep, if you make a small ball of the castable in your hand and toss it up in the air about a foot; if it falls apart it's too dry, if it runs through your fingers when you catch it, it's too wet. It doesn't seem like enough water, but I followed the instructions. Now it's covered with a damp towel to cure for 24-36 hours. Not sure if I have to fire the Mizzou before I add the Greencast or not, I'll have to email HW and see.
  14. New monster forge build

    Oh, in addition, out of curiosity I called a local industrial process company and chatted with them this morning. they make thermocouples in house, so I asked if they could provide me anything like the Omegaclad XL. They said the the Omegclad XL is the only thing available that's similar to "Haynes alloy" which was the best stuff available..until Haynes went out of business, but the patents are still being held by somebody or somesuch. The closest he could do was an Inconel 601 sheathed probe, which he admitted wouldn't last in a forge environment near as well as the Omega probe, and is more expensive.

    Owen, I usually just go to the "Probe Configurator" and make the choices I want for a product, then it spits out a part number. So, for example, a 12" long, type K, quick connect, 3/16" diameter (I wouldn't go less than 3/16, they're a little more stable in readings and hold up better), ungrounded junction (a little slower to respond, but less susceptible to electrical interference), with an Omegaclad XL sheath is PN KQXL-316U-12 and is $37US
