Fork Repair

Rivendell had this video in their latest promo email. I thought it was interesting.

Great video, it's amazing what it really takes to bend/break a weld or a tube. Seeing the force that it takes to straighten/bend a frame tube often makes me laugh, when folks post a picture of a small dent asking if the frame is toast or safe to ride.
Look at this poor frame, not saying that I would ride it but...https://www.bikeforums.net/classic-v...-gone-bad.html
Best, Ben

Looks to me like you've got about two hours to get that fork repaired and ready to eat with. (And that fork looks sized about right for the day.)

What I dont get is, if he had the tooling, why didn't he make a jig that would connect the bottom of the crown and the drop outs to a lever and be able to apply controlled force the first time.

Not to get too graphic, but if I did what he did during the first half, I'd be nursing a hemorrhoid for a month.

gearbasher,
That's a bit more information than is necessary.........

This was really painful to watch! Although the end results looks acceptable, I am not convinced the fork crown center line is aligned with the steering tube center line. Then there is the issue of how round the steering tube is now after squeezing the heck out of it on the vice even with the tool (AL?).

Please don't try this at home!

Wonder how many tools in that shop came from Harbor Freight suppliers?

But then again that Park alignment tool is the best. I am sure the most important thing about this repair is that it is successful and he is satisfied with his work. BRAVO...

Cold setting is often not pretty, but sometimes, a bit of ugliness is what it takes to undo a wreck. All things considered, it doesn't matter how you get there if you get the right result and keep the paint intact.

Shame he didn't have a leverage arm like the Park FFS to work with, but the "total-fork bash" approach just might have helped to overcome any potential twist of the crown itself.

That guy is the man. He has some other cool videos too. I like the vibe of his little shop. Wish there were subtitles.

If the paint popped or wrinkled, the steel was likely compromised. I just liked his mojo.

I've had some forks with traditional blade-bent-back damage which have had a bit of paint damage. Any cracking or paint loss has to be judged on the type of paint and its durability more than anything else, really.
