Right now, I'm mostly just staring at it, then reading! Lol. I need to get a few more tools. I've just used a dremel, all I've done is matched the case ports to each other and to the jug. Mine was waay off! I mean the two cases didn't even look like they were meant for each other, then where the exhaust ports met the jug they were off a good 1/16". Especially at the radiuses I just smeared never seize on the bottom of the jug then tightened it down to the case to give me marks to see where the ports landed. I'm still curious about the epoxy idea in the exauhst port. Oh, I did read that we must relieve the exaust port bridge because it will expand from the heat and screw up the rings. I need a good bore gauge and an inside micrometer. I also want a 90* rotary tool. I have a buddy that's a dentist. Gonna ask him if he wants to sell me an old one!
