For BEST one year (Warp XX - 2012) we needed a large winch spool to wind up the cable we were climbing. I took the largest hole saws we had (3.5" and 3" I think) to some plywood and acquired 4 disks of wood of equal diameter and 2 larger disks for outer guards. I used a .25" pilot bit in the saw, so I aligned all 6 disks on a 1/4-20 all-thread with glue between each layer and clamped overnight. I then chucked the all-thread into the drill press using it as a lathe to sandpaper the edges smooth. It worked fantastically.

A few more steps and you could have basically this wheel on nothing more than a drill press. The hex broach is unlikely, so maybe a versa hub on both sides.
