The Bicycle Full Frame Jig Kit includes all of the fixtures and hardware you need to get your bicycle frame jig (welding jig) started. You will need to supply 17'.5 of 2"x3" (1/8" wall) tubing and 10.5' of 2"x2" (1/8" wall) tubing for the jig to be assembled as shown. Structural tubing can be found at your local metal supply shop or welding/fabricating shop. The frame jig kit bolts together so you can easily reconfigure the jig or break it down to store or move. The head tube fixture will accommodate head tube angles from 40 to 75 degrees from horizontal. If mounted to a 2"x2" upright, it can go to 90 degrees by flipping around the rod block. The seat tube fixture will accommodate seat tubes from 30 to 90 degrees from horizontal. The dropout fixture clamps tubing or threaded rod from .3" to 1.25" in diameter (dummy hub/axle). See the individual product pages for each fixture in this bundle for more pictures and details.
All main fixture plates in the Full Frame Jig Kit are laser cut from 1/4" mild steel and are powder coated black.

- Excellent fixture at a very reasonable price.
After building frames with my home made fixture, the Chop Source Bicycle Fixture is a massive improvement. The kit was straightforward to put together. It is easy to adjust the angles and the various distances (front-center, rear-center, front-top, etc). Most importantly the fixture is extremely effective in maintaining fixed angles / positioning of tubes while tacking together. Best of all the price is very reasonable.
- Breath of Fresh Air!
The first real bicycle jig of its kind. Quality enough for motorcycles, yet user-friendly enough for bicycles. Very pleased to see Chop Source conform and making available complete bicycle frame jigs. Can’t go wrong!
