I have the front and rear hubs mostly done now. The rear was pretty easy, I just used the front. All I had to do was tap the bolts out to 7/16"
The front took a little more machining. I had already cut it down quite a bit and had my friend Mike fill in all the holes I made, then machined it down to a nice taper. Not as nice as a store bought spool hub, but a heck of a lot less expensive.
