I have received 0.081 and 0.072 brass wire, done the Z-bends with the DuBro tool, done some threading of the brass wire, and fitted spokes to hubs. What remains is to find stainless wire, buy a rim, and build a wheel.
Neither mcmaster.com nor mscdirect.com stock 15 or 14 gage stainless wire. They do stock 16 gage stainless wire.
