Metalsmith21 Posted October 4, 2013 Share Posted October 4, 2013 Was cirious if anyone used a big rig breakdrum lined with clay, and with doing that would it extend the life of the "fire pot" to last much longer? Quote Link to comment Share on other sites More sharing options...
Old N Rusty Posted October 4, 2013 Share Posted October 4, 2013 A very durable forge liner can easily be made from sand and portland cement ( not concrete mix) . Mix 3 parts sand with 1 part cement and just enough water to make a stiff mix that can be shaped into a bowl. This liner will insulate the fire from the large heat sink of the brake drum.

Charles R. Stevens Posted October 4, 2013 Share Posted October 4, 2013 I'm not a fan of cement for a refractory, heat turns it back into clay and lime. Clay and sand 1/3 works well, but I stray from your question. Claying your drum will alow you to insulate it, extending its life and making it less likely to scorch you in a careless (I phone substituted "Charles" which is appropriate ;-) moment. But it's big advantage will be to allow you to form an efficient ducks nest, helping insulate the heat as well as conserve fuel.
