page 43: Miscellaneous Aids. Tube blocks (with note for oversized tubing modification), clamping plates, and wedges for chainstay alignment in BB shell.
page 44: Fork Jig. Drawing and construction notes.
page 45: Main Triangle Jig. Drawing and construction notes. Using oversized tubing, the 1/8" shim is unnecessary.
