Thanks Guy
Yes I noticed we have the same mill too, my riser block is 4" which really helped, this is the first small milling machine I ever owned, my other mills were all 9" X 42"-49" tables, but this mill has allot of power and it's pretty darn beefy too, I was skeptical of buying it at first for the thought of it not being rigid enough, but after having it for a few years now I would most definitely buy another one,
Broaching a hex in the hub of the speed handle like a key way was my first thought, and to be honest I didn't want to make a tool for just one setup, but oh well I'll use it for making socket head cap screws and so on,

Thanks for your comments
Doug
