    Frame Jig

    How easy or hard is it to make a frame jig? What are the major components?
    Photos or Websites welcome.
    I have plenty of wood/lumbar and a machine shop at my disposal.

    Thanks

    the best source of reasonably affordable frame jigs is instructables.com

    There are other designs by the same person that designed the jig in the link

    Anyone know if it's possible (or advisable) to use something like the Bringheli frame alignment table for tacking up the main triangle? I feel like it would allow me to tack the downtube properly aligned, then tack the seat tube, and from there I could extrapolate a properly aligned head and top tube? At $800 it's less expensive than all of the other commercial options I've seen...

    yes, people use alignment tables to tack the frame together. You would need some fixturing. Alex Meade makes some frame blocks that would work

    My old frame builder doesnt use a jig but what he did was put the frame in the table and start aligning the frame before and after brazing.

    With the fork the same thing.

    If the frame is a one-off, an inexpensive jig can be made of 3/4" plywood and V blocks. I believe this jig was originally posted by Glenn Thompson of Daltex Custom Bicycles in Dallas years before he became a professional framebuilder. I saved the photos years ago from a post of his thinking I might try using something like this (long before buying my Bringheli jig). You have to be careful with the torch; plywood burns.
