In addition to everything else Amazon sells, you can now secure small portions of materials and mechanical parts suitable for building and repair. Amazon has teamed up with the supplier Small Parts (reviewed in Cool Tools previously) to supply a huge variety of metal tubes, springs, raw materials (titanium, nylon, polycarbonate, glass, etc.), gears, plastic parts, fasteners and bins of other stuff that tinkerers and mid-night engineers might need. Of course you can order from Small Parts direct, but Amazon's option takes advantage of their incredibly handy interface and billing system. Go to their "Industrial & Scientific" tab.
