Parts and Supplies Nuts, bolts, raw material, hinges, connectors, wire, plastic, pretty much everything: (My number one place to order from.) http://www.mcmaster.com/ Raw materials like tubing (chromoly and aluminum), light-weight supplies, some specialty adhesives. http://www.aircraftspruce.com/ For welders that have little experience with Chromoly I would start with 1 1/8" diameter, 0.058" wall thickness. We are building our current frame from 1 3/8" x 0.035" tubing. Much harder to weld, but a fair bit lighter. You may want to order some for the welders to try.
