Hey guys... I wanted to test this out so I took an old steel frame that was toast and cut it up enough to fit in my freezer. I hit it (HARD) with a hammer 3 times until it was really dented. Capped one end tight, filled with water, capped other end (not so tight) and stuck it in the freezer.

Well, I forgot about it for 3 days. I just remembered and took it out. Covered with frost... but amazingly the dent is completely gone!!!

All that remains is the unevenness from the multiple hammer hits.

What that tells me is that it is possible. With a quality frame, I would leave it outside for a few hours as described by others.... but my unscientific test looks great.

I am thawing it out now and will inspect closer tomorrow to see if there was any unseen damage due to the days long freeze.

Also, because I hit it so hard several times.... I think that if you had a "simple" blunt dent... you might get away with a nicely repaired frame. Really... I hit it hard!

The other thing to note is that my test frame is steel... but I don't know what kind. It seemed to be fairly light tubing, and the lugs were nice.... but the frame had long ago been abandoned in a friends yard and had been abused and repainted to the point of being trash. I think the tubing is slightly thicker than 531.

I take no responsibility for the loss of your PX-10, Raleigh Professional, or Constructeur frames. This information is for research purposes only

Um... no pictures.
