AIRCRAFT CABLE
Stop picturing a fat cable you can use to tie down an airplane. This is great 20–strand twisted cable from the aircraft industry, but at 1/16” dia, it’s sized more for a Chicago Cub than a Piper Cub. The cable is high–quality stainless steel, unjacketed and very strong. Use it to hang extremely heavy mirrors, make repairs, create bendable metal sculptures! Order in 15–foot or 100–foot hanks. Enjoy!

Solid Rubber Wheels
Hard, black rubber, 3" dia x 1-5/8" wide, with an axle bearing and a 3/8" ID. These wheels have been used a bit, so the treadless surfaces might be a touch scuffed up. Plenty of revolutions left in them, though.
