This actually works fairly well cold except its pretty snug & I have to get serious to get it bounced back out. I haven't checked the fit, but its possible the 3.5mm tool would make a socket that a 1/8 sae wrench would fit, I may try that tomorrow & see how schloppy it is.

That 6 or 7mm I thought I ws drilling into it was plenty of clearance for the broach to displace the materiel in front of it. The problem is that my mind was in mm's but the display was in inches and I had drilled about 3x deeper than I should have by the time I had the 'Duh' or senior moment. The damage is done now, so all I can do is make another one. Call it my Martian mistake. Mixing & matching inches & mm's is bad karma for me. > You could then quench and temper to preference. I don't have a real good way to heat. Mapp gas I have, but with the dime store valves in those things its hopeless, can't be adjusted for a good flame. I am a pretty good gas welder too but when I retired, somebody got away with the gas bottles I kept at the tv station to run my smith wrench with. I have a mig kit too, but that doesn't lend itself to heating at all well either. [...] Cheers, Gene -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
