  1. I do the same thing with resin. Permeable materials are better than solids in my experience. When I do something like wood chips or even coffee grounds I have to do it in a vacuum to get the saturation of resin. Other materials like shredded felt and construction paper work fine though with just a few tons of pressure and are easier to achieve an abuse-withstanding bond. -J
  2. Yes, very sad news. Doug was a great guy and always interesting to talk to. He will be missed. -J
  3. Yeah, I do 3 students at a time in my knife making classes and it's a little easier than one on one sometimes. People tend to feed off the input of those around them and it's always cool to see encouragement happening among the group. Takes some of the pressure off and when it comes to one on one instructions the other two often watch and ask questions I don't immediately think of volunteering. - J
  4. Yeah, check out the video of Crazy Ivan and I drifting the holes in the block of S7 for a striking anvil over in his thread. That's my Soderfors under that 65lb block, no babying required. J
  5. That would probably be some of my misc tools and punches floating around in the tray on the anvil stand. J
  6. Yeah, it amazing how people can always tell what I do without them asking. They just look at the hands, clothes and coal dust. Lol J
  7. We just do it under the power hammer thanks to some tooling and have never had a shank get stuck as the metal contracts as it cools. J
  8. If you're just looking for tempering and not an oven that can ramp up to 1750°F, which has never been an issue for me because I use one of my gas forges for hardening, here's my cheap $150 505 cu in tempering oven. I can do about 40 blades and Pete could throw 9 hammers in this thing all at the same time. Was walking through Ollies, found an electric smoker for $119, insulated the bottom with some scrap kaowool, added a PID, type K thermocouple (it has a port for one already even if that wasn't their original intent) and wired the factory controller through a relay (2 wires) - viola! Simple, spacious, gets the job done very well and even looks good. Only things I'll be adding in the future is a convection oven fan for more equal heat distribution ($60) and a panel box on the side for the electronics. Proving once again that you don't need to over complicate things. J
  9. If you do ya better plan to swing by the shop as both Pete and I will be teaching that day. He's doing a full tong making class and I'll be finishing up the second day of a private knife making class but we'll have a cold beer to wash the road dust out of your mouth on hand. J
  10. Lunch today for Pete and I. I'll let the pictures speak for themselves. This is the true meaning of Pittsburgh Rare. J
  11. To add a little more to what Pete said, it was kinda a tough call between a wood ring going around the the base of the steel ring to give the control, but this system really gives us 180 degree on the fly vs anchoring something into the concrete which limits future positioning of the hammer. Either way, the ring itself was nice but didn't offer the control we were looking for so the pedal on the treadle is really kickin' J
  12. Pete (Crazy Ivan) and I have been working on a new air hammer here in the shop over the past few days. Most recently we've just been running it through the paces and tweaking where it needs to be tweaked. We're still working on a video of it in operation but probably still a few days off until I have time to edit our footage together into something informative and entertaining. Anyway, I figured I'd take a few pictures and show ya how she's looking. Tup is near 65lbs with a max throat of 13.5", plenty of room for top tools. Speed is 124 bpm, but it might be sped up with some compressor system modifications I'm considering that would benefit the entire shop. Don't worry, there'll be plenty more details in the video. The design and planning were our own, but drawing inspiration from the work of Ron Kinyon and Tom Troszak, the simple air hammer and bull hammer styles respectively. I've never seen one of Tom's bull hammers in person or really seen how they operate but I managed to find a few 20 second YouTube videos and stills which gave me enough concept to work from. The whole design itself requires a fair amount of rigidity, and without Pete's masterful welding I don't think we'd have pulled it off. That being said, can't wait to share a video with you guys, but until then enjoy some stills. J
  13. The best I've found is from Yoyodyne Propulsion, Inc. They have a Spacial and Dimensional Research department that's putting out some interesting things on the engineering front. It's one of John Whorfin's projects and he's sort of a tyrant for perfection so you know they're going to get it on the money before they release it from alpha testing. J
  14. For those wondering how that new hammer is coming along, here's a pic. Expect a new thread with video soon! J
