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?

how thick was the tubing

The tubing is .065 wall.

Do you ever find the mandrel bend to be smaller than the unbent part of the tube ?

It is not mandrel bend tubing...this is what I use:



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.

Google- sanitary fittings butt weld.

Nice going, you gave away the greatest secret of all time.....GOOGLE.

most stuff i work with is .125 wall tubing with my mandrel bender it doesn't like thin stuff tends to stretch and not stay the same size when bending .065 is thin stuff to bend

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.

Awesome work! I'd like to do headers for my 240Z at some point, there are some on it now but they are not well thought out.

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?
