Bicycle jigs and tools

In  the course of building a few of my own bicycles I’ve built quite a bit of my own tooling to hold, fixture, etc… Based on pictures of some of the nicer Anvil and Sputnik tooling, I decided to draw up and machine my own.

The first necessity was being able to hold tubes in the vice. Made a set for a couple different tube sizes.

The chainstay tooling is most similar to the Anvil.

I used mostly aluminum for everything and machined on a bridgeport style mill.

Frame jig is of the 80/20 variety with custom made bits to interface with the bike. Mounting of the dropouts has changed a few times. The first iteration wasn’t perfect!

I design dropouts. Here’s a couple examples… This first set went on my personal track bike.

Frame 3 Dropout

I build my bikes exclusively welding… no brazing skillz here so I like hoods!

These cross/road dropouts have a polished stainless cover too.

Here’s a set that I reverse engineered. A very common dropout supplier was on back order. I re-designed, mocked up with the 3D printer, then had 20 sets CNC’ed.

Drive Side 5

Here’s what the cross/road dropouts looked like part way through the process…
