joshua.M Posted November 17, 2010 Share Posted November 17, 2010 if i cut a hole into a pice of 3/8" checker plate and weldded a break rotor onto the bottom will that work for some medieum sized work or would i need to but firebrick all over the top to make it deeper Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted November 17, 2010 Share Posted November 17, 2010 Yes, no, maybe depending on details you have not provided---like how big/deep a brake rotor you are using---though most folks use a break drum rather than a rotor. Quote Link to comment Share on other sites More sharing options...

thecelticforge Posted November 17, 2010 Share Posted November 17, 2010 I am thinking that if you welded the drum to the bottom, the expansion from the heat may crack your welds. I use a sheet metal/brake drum forge for demos and I just let the brake drum rest in the hole that is a bit smaller than the widest part of the drum. That way when the drum heats and expands, it just moves up a bit higher. Gravity has yet to fail me. :) Quote Link to comment Share on other sites More sharing options...

son_of_bluegrass Posted November 18, 2010 Share Posted November 18, 2010 4 inches deep is enough for small projects with coal or maybe charcoal. It could work for medium projects with coal but not charcoal. A bit more depth (2 or 3 inches) would make for a better forge. ron Quote Link to comment Share on other sites More sharing options...
don't tread on me Posted November 18, 2010 Share Posted November 18, 2010 I have looked at diferent ideas and I hd a good idea, I think. Us the disk from a farmers disk plow and you could make a forge like a riveter forge. Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted November 18, 2010 Share Posted November 18, 2010 To fill in a too deep forge pot you can line it with clay mixed with ashes. Or to use a too shallow one you can ring it with a piece of strap bent into a circle to make a "fence" to allow you to pile your fuel higher. For my small brake drum forge I put in an 8" fence of sheetmetal bent into a "C" that would slip just inside the wall of the drum and the opening of the C was just the right size for me to get stock into the fire through the gap. I also cut a "mousehole" across from the gap to allow me to shove long pieces through. This was my main billet welding forge for several years and total cost of it was under US$25 including blower and the fanciest tool I used to make it was a 1/4" drill, (no welding!)
