Starting this Saturday on new model mini out of 12 inch pipe. I have enough for two, so will be building them in pairs. Will be more of a traditional reverse flow design than my last mini, these will be for re-sale.( I have had so many people wanting to buy #20) I also need to keep the weight down on these, I cant hardly even pick up #20. No 1/4" plate will go into this one, Im going with 3/16" pipe and 1/8" internals.
