Using the hubs linked above on eBay?

I'd need to get my hands on them to be sure but the way I currently envisage it is:

- put an M10 penny washer on the drill output shaft
- screw the UNF hex hub onto the drill shaft
- slide the Banebots wheel - with corresponding hex hole - onto the UNF hub (I'd also make sure the hub is cut flush with the wheel)
- secure the hub in place with the M5 reverse thread screw and an M5 penny washer.

The purpose of the two washers would be to stop the wheel moving from side to side on the hub, as well as their standard washer duties.
