Bike Frame Fixture by A.Rabe

Hey my friends and bike builders,

recently I wanted to buy myself a road bike. But then I started thinking about to build on by my own.

(I’m not a total beginner when it comes to work with metall ;D)

So I started researching on forums like these and noted down all information about Frame jigs I can get. I also inspired myself from pithy bikes, cobra frames and Farr…

After all the effort of researching in the depths of the internet, I finally came up with a Idea and a first sketch.

Thereupon I designed my ruff sketch in fusion 360. And I have to mention, that I’m pretty amazed how it came out. <<3

But now there is the point where I need your help.

Befor I’m going to buy all the aluminium extrusions, the screws and the wood. I would like to know from you (experienced bike builders), what do you think of the design? I really don’t want to waste money if something doesn’t works properly. Do you think that the construction will do its job?

I really appreciate every comment and answer on this post and I hope your answers will advance my work.

Secondly I’d like to know what the mounting dimensions, in the middle of, for example the paragon machine works dummy axles are? Is there a standard sizing for these dummy axle mounts?

If you don’t understand what I mean exactly, I marked the spot in the picture.

Would be nice if someone tells me. <3
