- Bending bicycle tubes can be fickle, difficult work: you'll often get rippling and kinking in your tube if the set-up and tooling isn't just right. But fork blades can be an exception to this. I made this crude fork blade bender 8 years ago, and it actually works pretty well. It's a cheap and easy project to make one, so I shot this video to explain the details.

Like listening to a master builder. Thanks for the lesson.
Enjoyed this one!
What would you charge to add some rake to a fork? Surly steamroller fork, 38mm rake, id prefer something in the 43/45mm range
Hell yeah dude!
hello Jason , I'm thinking to convert a simple plain gauge steel frame to a freestyle fixed bike, for the fork situation im thinking of a lugged or unicrown fork ,but I would like to know if its still rideable if u reverse the curve? curved to straight fork leg, by bending back to original shape , and rebraze or tig some other dropouts
dawg just find a unicrown straight fork. Bending metal fatigues the molecular structure, and bending it back will just give you a wonky weak point in the middle of each leg -- probably the worst place for two weak spots on a bike. try this: get a piece of clay or play-doh, roll it into a straight even cylinder and take a picture. Then pull it around a bottle or can to bend it, and do that again in reverse to straighten it. Make sure you're pulling, not just wrapping it. Compare the double-bent clay to the original picture you took. More or less the same thing would happen to the molecular structure of the steel fork legs if you tried to un-bend them. Hope this helps! If I'm wrong anywhere here, someone please call me out, cheers.
Are you going to sell fork benders at some point? I'd buy one!
The tube bender that I make and sell does not have the capability currently to bend fork blades, but I'll try to make a supplemental kit for it in the coming months that makes traditional, tapered fork blade bending a possibility. As I said, this is an easy, low stakes tool to make yourself with cheap, simple tools, so it's not a bad one to make yourself if you have the itch, but certainly what I would make and sell would make the process more enjoyable and simpler.
Very cool and informative video on such a wonderful tool !
Why Not ??? Use a Solid Bar Stock in the front end, thats a part you dont want to break . Also with frame changes Why Not use a thicker wall pipe section instead of re use of cut out sections . My concern lays with strength lose from flexing already weak tube. For as little as steel costs for safety is worth over savings. I do like your bender and Designing . Please do a video with you useing your bender.I make tools also and find mostly there is certain methods used with our home cooked tools to get the best results ..Thankyou..
I’d like to see this tool in action plz
all that and not a demonstration on how its done
DFAR TOOOOO LOOOOONG...... ON AND ON AND ON AND ON AND ON
