today I made a spare axle for a Roleez kayak cart. the company builds them using 20mm tubing, and of course 20mm ID wheel hubs are hard to come by here. however, 3/4 inch is really close, and you can get Marathon foam tires with 3/4 inch ID bearings. so I bought a piece of 3/4 inch steel tubing, and was going to attempt to bend it the same shape as the Roleez, but figured what the hell, just use it straight and it should work fine. I already had the Marathon wheel assemblies.
if it turns out we don't need it, I can still use it for other projects, such as wheels for my windsurfing board and/or my next Kinetic vehicle.
