Thanks for the offer Tony, but I think I will just use 5/8" mild steel. My design will be very similar to what you did. Just different material. Funny you should mention JB Weld: I had a 750 Yamaha with the outside right hand carb held on by JB Weld for Years. Never came off until my nephew pried it off. I'm going to use JB Weld to put on the finishing touches and get it leak free after I weld it on to the manifold. I use to weld mild steel to cast with hardwire all the time at my old job, but I haven't tried it with oxy/acetylene which is all i have at home. I'm going to get a manifold out of my buddy's junk pile and run a few practice beads before I tackle the job.
Boo
