Not sure I posted this here or not but this is how I did large lots of WW or whatever.

Nice!!

Thank you. It could be better up I wanted to keep it highly portable.

I do it the same way, works just dandy.

Nice set-up! I do something similar. I have a 2X6 that I put over the tops of two 30 gallon barrels with a 1/2" X 6" steel piece of flat iron to put my ingot molds on. It lessons the bending over and steel bar acts as a heat sinc. I also tack welded a few Harbor Freight steel stamps together for marking the ingots. I used the W and an upside down M to make a WW for wheelweights, a PB is soft lead, ect.
