[gingery_machines] Re: Propane Foundry Questions

 

Clane,

I am planning on building a modified version of the gingery gas fired furnace. I cut up a 30 gallon oil drum (14" OD) into three sections and going to use the 8" cylindrical concrete form that Rex mentioned for the ID. (Purchased at home depot for about $8) I'm using a commercial refractory since there's a supplier nearby and ignoring extra insulation at this point. Also designing around the 1/4" mike porter burner. This is after following Rex's advice :)
