Removing a frame dent using ice - does it work?

[Fudd]

There was a thread here a while back on the same subject and someone posted a link to a mx forum where a guy was filling dented expansion chambers full of water and putting them in the freezer. As the water froze it would expand and push out the dents. I'm not sure if it would work on a frame tube, or even if I would want to attempt it on a good frame, but it sounded like an easy fix....

I posted this fix last year to a similar question-- A long time ago I had a chrome plated Eddie Soens track bike frame with a large dent in the top tube. Joe Breeze fixed it for me. He had a fitting he had made which was a solid plug to insert in the head tube. This plug had an L shaped hole through it that went from the top (when inserted in the head tube) to a right angle turn to come out at the middle of the top tube. The hole in the plug had a relief cut and an O-ring inserted for a seal on the inside hole and was drilled and tapped for an automotive grease fitting on the outside of the top hole. With a drill he made a hole inside the head tube into the top tube and lined up the fitting with it. Then he filled the top tube of the frame with oil, re-inserted the fitting and used a grease gun full of oil on the other end of the fitting (the outside top) and pumped up the pressure until the dent popped out! All that was left was to drain the oil out of the top tube and reassemble the now perfect bike-even the chrome was perfect!

Clearly what's needed is a Joe Breeze - available in a handy size box at all good LBSs

Why not just fill the dent and do a paint repair job, a couple of grammes of plastic padding, one might just have to pedal harder.

its only a dent, if you want yer bike to stay in showroom condition leave it in the showroom
