Details on full setup: https://github.com/andrewsuzuki/makehaven-framebuilding-setup
At the core of any bike framebuilding setup is a frame jig (technically a fixture, not a jig). Industry-standard frame jigs run at $3000-5000, but we can make our own for $500-600.
We already have an oxy-acetylene setup, which is good for traditional lugged and fillet-brazed construction. While we don't have a TIG welder yet, the jig should be future-proofed with integrated argon purge lines. MIG doesn't work with the thin-walled tubes used in bike frames.
In addition to the frame jig, there are some other tools and fixtures we can DIY:
- Jig stand $100
- Chain stay mitering fixture $70
- Seat stay mitering fixture $70
- Disc brake fixture $30
- Primitive tube / fork blade bender $30
- O.L.D. gauge $5
- Braze-on clamp/fixture $10
And tools that should probably be purchased instead of DIY'd:
- BikeCAD Pro license (up to three machines) $380
- Paragon dummy axles $70
- Paragon tube blocks $75
- Hole saws $50
- Hole saw arbors (for Bridgeport) $35
- Slitting saw + arbor (for Bridgeport) $55
- Dynafile (used) $300 (optional, but handy, and good general-purpose metal finishing tool)
Then there are a few more expensive "bike shop" tools that Makehaven doesn't have, but people can just go to Devil's Gear or BSBC for them.
I would be happy to sign up as a bicycle framebuilding facilitator so that all of these tools can be put to good use.
