Jobbing (leather tools)
sbwhart:
Hi B:- that sounds painful there is nothing worse than a burn for pain,
Was the bolt heavy. :D
I Gave the the punches a bit of a polish and wired them up for tempering, any one who's tried tempering will know that the colour changes happen quickly I read that sitting the job on a bed of sand would increase the mass and slow down the rate of change, so I though I'd give it a try.
Her's the job wired up sitting on a tin with about 1 1/2" of sand, I sat the tin over the torch, but it was taking for ever to heat up, took about 1/2 of the sand out still a bit slow took a bit more out about 1/2" of sand left, this work fine each colour transition took about 5 seconds.
I was after a purply blue colour 280 - 300 deg C I just left them to air cool.
Now for the fun bit with the tool post grinder, I dressed the wheel up then twisted the compound over to 40 deg, worked like a dream, nice sharp corner a good finish.
Well do they work yes they do tried them out on a scrap of leather under an arbour press onto a bit of plastic.
Whilst using the press it gave me an idea for Johns internal gear tooth shaper.
Have fun

Krown Kustoms:
Very nice, they look great.
Did you temper them by heating the tin of sand from the bottom?
If so I will have to try that, I can never get good results by direct heat.

sbwhart:
B Yes thats what I did I sat the tin on tripod stand with the burner underneath, I just used what we call builders sand that I dried out first.
Good luck
Stew
