I just spent the last few months working on this big(for me at least) forge.
I used a coach bus rim for the fire-pot, then welded 1/4" steel diamond plate to it to close up some holes, welded on some legs and supports, cut a 1 1/2" hole for the pipe, welded the pipe in place, added some wheels and I have an old electric blower rigged up to a power regulator.
Now I am just about ready to start it up but I want to make sure the heat is not going to melt away the welds that I made, they are solid welds (been welding for 5 years). I joined on here just to see people's opinions I was thinking about adding a clay and sand mix to the fire-pot to give it some insulation but I was wondering if that would be overkill or not?
Any tips, tricks or advice would be greatly appreciated. http://amsterdamforge.yolasite.com
