I used to collect bent EB44’s when I would buy them. I didn’t know they were bent when I got them, but I built an axle jig for narrowing and used it to discover bent housings. I also used to straighten them. They will move when you put about 40 tons on them.
The last one I did, I pressed the tube using my 4x4x6 cast V-block. I got it straight, and decided to over-bend it and push it back to make it perfect. That’s when the cast block exploded, the housing jumped out of the press, and I had to source some new underwear.
It happened so fast that I didn’t even move, or flinch, or blink. Just bang, crash, thud…what???
So yeah, I saved a housing, but I destroyed a $900 v-block. So no more D44 fixing for now.
