getting back into the shop [Sep. 9th, 2011|12:05 pm]
Doug Ayen
Between work, WorldCon, a trip down to SC to visit Mom, an earthquake, cleaning up after Irene, and general lameness, I haven't even been in the shop for a couple of weeks. And, yes, the sword maker seminar is next weekend. All I have to show for my work is a lump of metal, and one that's too small to boot.

So, I'm going to try to at least get the sword to a forged shape, maybe we'll have a suitable long forge and quench tank at the seminar if I can get it that far. Tonight, that means working up the rest of the loose steel into a block, then a couple of folds, mate the two pieces together, and if possible insert the core. Saturday, with any luck, I'll start the final forging. I'd like to use the small rolling mill, but I doubt I'll be able to make it work.

If anyone good with 70's era electronics would like to take a look at it, the rolling mill is part of a student's metalurgical workbench from some univeristy. I have wiring diagrams, but just don't know where to start with troubleshooting. The thing is controlled by what look like hand-etched circuit boards, slotted into a wooden holder and held down with string, with lots of identical wiring going everywhere, the whole lot powered by a 24v DC power brick the size of a loaf of bread (french baguette). I'll buy you dinner, at a good restaurant!

I don't think I'll continue trying to video the process -- sorry, but it just takes too long to edit the stuff down. I may try again later, but it really slows me down, and I just don't have the time right now to stop and reposition cameras & etc. I'll try to keep the pics coming, but again, it's time not spent making stuff.

Can you bring it or the schematics to burgerfest?

"It" weighs about 1200lbs, but the schematics are in a little yellow 3-ring binder -- I'll bring it along if you like.

Sure, bring the binder. I've been able to repair Elec-trak electronic controls, that's diodes, SCRs, and capacitors acting as timers for sequencing. Usually it's the diodes that disintegrate, replacing them means another 30 years of service.

See you there.

That would be Spam you want. He's purpose-made for that task… and local!
