I want to build a steel boiler for my loco, not bothered what type but no one seems to have any drawings – they must exist as the americans seem to mostly use steel. Does anyone know of any, or of someone who would be willing to produce any for me? (paperwork/weld regs easily taken care of).I know the pros and cons of a steel boiler but at the end of the day they cost peanuts to produce compared to copper ones. I have no problems makinf 3 1/2 gauge cu boilers but the tig set goes into meltdown at the amps needed for bigger stuff…and Im not silver soldering it, the cost is horrendous!!
