Pretty simple to make, All you need is: A junk axle, an extra axle nut, a grinder with a cutoff wheel and a some sort of way to hook it up to a drill motor, I used a socket/extension/adapter etc.... I was in a hurry. You could very easily make one that turned truer with a minimal amount of effort more than I put into it, but you get the idea, and it worked great...
This is what I came up with... It is an axle nut with 2 of the 6 "parapets" (extra credit if you know what that is!) left on opposing each other, threaded to a piece of axle stub that I cut off an old axle, then I cut/ground the end to fit into a 7/8" 6 point socket. It took a couple stages of being pissed at the results to get it to this fine piece of equipment. First I turned it with a ratchet for a while but ended up chucking it up in a drill motor. This would have been a MAJOR timesaver if I had evolved it on the drivers side (did that side first).
