Thread: Straightening a rear housing

This is beautiful, I had to share it with you.....

Keep in mind that you can kink the tube if you try to bend it cold. I've seen this a number of times with setups far more sophisticated than this. Heating up the tube also requires a light touch whenever putting pressure on a bent tube. Personally, I prefer to just replace the tube with a new one as it leaves no doubt as to the integrity of the repair.

Techinspector1---Thank you. That is a very nice article. I never really knew how that was done untill now.---Brian

You know what my brother and I did once. We had an 8" rear that a well known rod shop (who will remain name less) who welded some four bar brackets it. They warped it pretty bad. We heated the other side of the tube with a rose bud tip on a torch and dunked it into a five gallon bucket. The cooling shrinked the metal on that side making both sides equal. We made it PERFECT doing it this way. That rear is in our friends Model A and has thousands upon thousands of miles on it without a problem.

That's a fairly standard way of truing up driveshafts that have a little runout.

I would be wary of heating any part of the driveline or chassis and "dunking it in cold water"!!! Yes, it will probably shrink it---It will also crystalize the molecular structure of the metal, and make it very brittle and prone to "catastrophic failure"---as in shattering under sudden stress loading.

I straightened an 8" Ford housing in my roadster thread. It, too, had been welded too much on one side of the tubes. I equalized it by welding on the opposite side. Simple. I'm using it under my track roadster...
