I found that a small buck boot transformer worked well when I made mine. Went a little overboard but it works great as long as I remember to drop the voltage down.
I used a 500 watt buck boost, wired for 120 v in 6 v out delivering a max of 90 amps at 6 volts. I also use a dimmer switch to lower the voltage and always start low. With 6 v and 90 amps you can easily vaporize small details on an engine. Fortunately the parts were available when I did my stupid and got a lecture from SSLS in the process. If I had it to do over I would probably looks for something in the 200-300 watt range max. I have yet to find something I can't solder with this. Carey Carey Probst Member, M.I.T.
