new steel [Oct. 23rd, 2007|11:35 am]
Doug Ayen
Just bought some more steel for the collection. Admiral is having a "box sale" (still a couple of boxes left, apparently), so I picked up a bunch of S30V, one of the new high-vanadium stainless steels, from Crucible, so I have high hopes. I also picked up some more O1, and since L6 is essentially no longer available in a knifemaking form factor, I'm switching to 15N20, which has enough nickel to act as the high-contrast component for some pattern welding. I also picked up some 6" wide ATS34 for my efforts in making a dishwasher-safe pizza cutter. I've been doodling pizza cutter designs for a while now, so I've got plenty of ideas for making some neat-looking cutters, even if they're not damascus.

I've been spending more time in the workshop, though it's still a struggle to find the energy after work, and even on the weekends.

I tried forging out some 2" x 1/4" 440c I had in stock into some disks, but the stuff moves so-slowly I went ahead and just bought the above ATS-34. I prefer the ATS, it's a better steel, though 440C is a bit more stain-resistant.

I did some tuning on the power hammer, and now it's hitting square again. Turns out some of the bolts holding the top bearing assembly (babbitt bearings) had loosened up enough that the shaft wasn't quite in-line. An easy fix, as I'd thought I may have to machine the dovetail square to the ram, not a task I was looking forward to. It was interesting -- you can over-tighten the bolts to the point where the shaft doesn't move at all pretty easily, so it came to the point where I was torquing the bolts, trying the movement, and if it was too tight backing it off. After a couple of rounds I've got it so there's a bit of friction, but the shaft is now tight and the hammer is hitting true.

That said, I'm seriously thinking of selling the hammer (anyone want a 1927 50lb little giant power hammer, 220v single-phase 3hp motor, adjustable arm toggles, new bottom flat die, older flat suitable for modification, one texturing die, pickup only in Berryville? :) and using the proceeds to buy a forging press. I'll probably just toss it on ebay with a reserve of what I paid for it, looks like even the 25 lb hammer are going for pretty good money. For the kind of work I want to do, the press is a better tool for the job.

Hello from Linh Thai; former UUNET guy...

Hello Doug,
