Yet Another Dented Top Tube Question
So I could get this vintage Trek 950 mtb frameset (last of the lugged USA made) for next to nothing, but among some other things, there is a dent in the middle of the top tube. I'm looking for a project but not sure this is going to be worth it.
Do people think this is possible to fill up with brass and sand down, or will it require a top tube replacement? For what it's worth this is made with True Temper AT ATB double butted chromoly tubing, according to the Trek catalog. https://images.craigslist.org/00505_...2_1200x900.jpg |
If you just want to fill it and repaint it then you'd be much better off with some kind of filler putty. There is zero structural advantage filling it with brass or silver....in fact the added heat and then all the filing/sanding will make the tube nothing but weaker.
You could roll the dent out with some wooden blocks and it will help but you'll never get it looking perfect that way and it will still need some filler before paint. dave |
If it were mine and I were looking to turn that frame into a project (because the frame meant something to me) I wouldn't worry one bit about the dent(s).
If you want to refinish the frame (looks like there's at least some surface rust on there, perhaps more) I'd sand down the suspect areas and see how bad they are. If it's no big deal I'd have someone else blast it (with whatever material is appropriate for that type of frame - ie they shouldn't just go hog-wild and use whatever happens to be on hand) and powder-coat with your preferred color. No need to fill the dents, or anything like that. Good Luck |

Another thought:
If this were a relatively new frame then it might make sense to get rid of the dent, or otherwise try to minimize it. However, since it isn't a new one it's better (IMO) to just leave the dent as is. |
Wow, appreciate all these great replies so far!
Ok so good to know this should be an easy fix. My ideal plan is to make some other frame modifications and repaint to make my ultimate commuter bike so I probably will want to at least fill with putty to make it look nice. |

Ride as is. It’s patina and not unsafe. This is steel’s greatest quality. It is very tough.

Lol yes 'nice commuter bike' might be a bit of a contradiction, but if all it takes is some putty I'd rather not see the dent is all!
Thanks again for everyones thoughts so far. |

If they're very safe ("Is it safe?" - to quote Laurence Olivier) then great, the bike can be as fancy and nice-looking as you like, but if they're iffy, then you'll want to consider not just how the bike will look to you, but how attractive it might be to potential bike thieves who might happen to see it. Good Luck with the project. |
Putty and a sticker from your favorite local brewery over it.

In the the "ride it as is or fix it right camp" ie tube replacement.

I once had a set of these blocks for a couple of tube sizes, but I got rid of my vise during a move (too heavy) so I'm not even sure I still have them. But, they did take out most of the dent, just not smooth like original, so more work was needed. I remember filling with repeated primer sprayings, sand, more spray. Or, as someone else mentioned, put a sticker over it. |
