But with this new method putting a nozzles pipe ring in, this is much easier to install and will receive more heat on all sides, which is very good. I could still make the smooth hopper barrel to fire tube transition with nozzles coming out this would create the hot gases under it, that Max Gasman talks about.
My conclusion is this if metals can expand and contract freely they will not crack as easily. And I am pretty sure I see this in Joni’s build. I like trying to figure things out. I have spent about 5 hours studying this if I am wrong oh well no harm done. It is fun and I like a challenge and a mystery.
