    Pull small dents out of steel frame?

    I know there are some ways to pull out dents out of car body panels and such, but is there an effective way of pulling small dents out of round tube bike frames?

    I have an o.g. Soma Groove 26" frame, never been built, but does have a small dent in the top tube that I think would be rad if I could pull it out. Not one to worry about structurally, more of a aesthetic thing.

    I think that's the way to go. I had a steel frame with some small dents and the guy who powder coats for me filled them.

    considering the force needed to create the dent, i'd bet it's next to impossible to pull it...

    Take it to a body shop and see much they'd charge to pull it.

    I tried a few different things to pull out a small dent in the top tube of my frame, none worked and the paint has a bunch of lil spider cracks from where I used dry ice... yeah that didn't work. I read about using wood blocks, pressurizing the tube to push out the dent (not gonna try that), even pouring water in the tube and freezing it yikes. In the end, if you want it to look new you will have to take it to someone to remove paint, fill (bondo or perhaps a braze fill) and then off to repaint. I used a thin coat of clear nail polish to cover the clear coat cracks in the paint job and kept riding. I figured it'll get other dents since I'm using it and the one that bugs me will fade amongst the rest.

    This dent occurred as I was building up the bike, even before I put a chain on and swung a leg over... set it down on the ground to adjust the stand and the bike f'in rolled and fell over. I know the pain... Anyway, if this is wall art repair the dent. If this is to be ridden, what are you waiting for?
    I don't know why,... it's just MUSS easier to pedal than the other ones.

    may help reduce the dent so you can use less bondo

    That's a good video, I've only seen that done with wood block rather than the aluminum blocks.

    I dunno about that on a steel frame due to most of them being heat treated, the tubing that is. You'd lose the properties from the original treating but since its steel you don't lose as much. I think as localhost mentioned/posted the vid for frame blocks, that is probably as good as it gets, then a small amount of bondo, etc will cover the rest.
