Wow that is really nice. I wish I could weld half that good. Stainless looks so great.
Do you bend the pipe yourself or get prebent sections and cut to fit... Even the cuts look tight. Thanks for the pictures.
Model does not matter. The hand does the welding, not the machine. All you need is a footpedal.Quote:

This was 60mm mandrel bent 304. The bend part from a 180 and a 45 was about 1mm smaller in diameter. So when I tried to fit part of a turn to a straight piece, I couldn't get a nice clean joint.Quote:

how thick was the tubing
A little trick a bender showed me when bending thin tubing he would fill tube with fine sand and cap both ends then bend then tubing wouldn't shrink while bending
That is some nice work! After you weld everything together will it bolt up easy or does welding tweak it?
The tubing is .065 wall.Quote:

It is a sanitary fitting, and has the same diameter all the way through. These are perfect.
The flanges and flex pipe gets welded last, this it to allow for proper fitment. The stainless dos shrink a fair bit when welded.Quote:

yes i can use google, but i figured since you in alberta, you have a source close to home.
Well, if you want to buy this stuff in Alberta you will pay 2.5x what you would pay for it down south.Quote:

What are you doing to get such uniform ovals out of the round tubing going into the flanges? Your not just bending them in a vise are you? I would think that would "pinch" the mid-point on the tubing. Are you buying some pre made stuff for that?
Do you experience any heat issues with the transmission or other parts? Do you find any value to ceramic coating the hot side tubing or using a turbo heat cover in an application like this? S/F.....Ken M
Too bad all of that nice work is going to be hidden from view. Really nice job and it looks like it won't reduce under-car clearance much at all.
I'm curious about this as well.Quote:
