Jerry, the parts are made... It is a little tight to finish welding them... thus the rub... The long 3 won't fit in the space between the tubes... so bad planning on my part... when I was mocking it up it looked like it was doable.
I will find a way
PJ, When you say large, do you have a pic of what you are trying to explain to me... I'm not a pro but I am always willing to learn and try.... I have a Weldcraft 20 water cooled torch on an old Aircrafter 330 tig.
If your're not busy this week I'd be happy to have you drop by to demo....
ya I know...
edit... hopefully the local Miller store is a good welding supply, they did have long #3 in stock.
