I think it may be easier to make hinges from scratch than modify existing
hinges. I've made small hinge-like plates, and in brass on a small scale it
isn't that hard. Machinist's vise, hacksaw, file, soft hammer, sheet steel for
the plate, pin. Scriber for layout, sharpie or (if you go posh) marking fluid.
Drill, bit, countersink. Torch for annealing, possibly optional. If you can't
find instructions on line, ther must be a description in Moxon. I can't recall
making actual hinges, mind you, so maybe I shouldn't talk; but for a group where
members make godhelpus infill planes and guitars and suchlike, hinges should be
a snap.
