could anyone post pics or idea's on the right way to weld a swing axel torsion tube to a sandrail frame. working on my first old school 4 seat beam car and want to get it right the first time ,any help would be great.

Use JB weld or elmer's that will work better than your welding.

is that the same stuff that our crack maintenance team uses at work

Here is how I mounted mine, not a swing but it should mount the same.

I'm not sure of the question. You want it as square as possible, of course. Pay attention to the horns so you get the engine where you want it -- I tilted mine up a few degrees to help keep the engine out of the sand. I had to cut a few pieces of 3/16" plate to fill the gap between the ends of the tube and the frame.

thanks for the help, ijust want to make sure that it mounts square to the frame. a few degrees out of the sand is something i didnt think of but sounds like the way to go . stay tuned ill post pics as i go just incase somebody has any input as i go .Thanks from a newbe

I have always blocked the lower floor section of the frame off of a level floor with cut pieces of 2x4 or something similar. To determine the height of the blocks set the torsion on the floor with the frame horns or tranmission mounts sitting either flat on the floor or with a couple degrees of upward rake. The main torsion tube will be off the floor at this point at least an inch probably more. Measure from the floor to the center of the torsion tube and deduct half of your tube diameter. So if your frame is 1.5" tube and the torsion center is 3 inches off the floor your blocks will need to be 2.25" tall. This sounds confusing but it really isn't if your doing it. Put the blocks at the front and rear of your main floor section of frame so it sits level to the floor. Next slide your torsion up to the frame and center it side to side. Your frame tubes should be centered on the torsion tube at this time and you now can weld them in solid.

my buddy actually angled his down a little bit. He then notched the rear motor horns and bent them up then reinforced them. This gave him more clearance without cranking up the torsion.

thanks to everyone for the help i think i almost know whats going on .as long as im square front to back and side to side it should work out ok. using the blocks of wood seems like the easy way to go.
