Well, last year, we had some serious problems with wheel mounting. Our teacher said that we should use pins that go through the shaft, to fix the wheels on the shaft. This did not work out all too well. One of the pins broke on one side of the shaft, and so it was wobbly, and on the verge of breaking during competition.

Is there any way to fix wheels on to a shaft, which is not permanent, which will keep it on there? All the tools i have are 40 year old non-cnc lathes, drill presses which are not too accurate, a milling machine, a bansaw, and various powertools.

I would also like to tell you guys that we have had some bad experiences with set screws, and unless you have a way to make them better, weve already been down that path

thanks,
