I had a hub made to receive the cutter. Not sure if I need to but this will allow me to remove the cutter. It will allow me to try different things in the future.
The hub is 3/4" steel with lugs pressed in. Now I need to able to get it centered to the shaft. I had them drill a 1/4" hole in the center for that purpose.
I centered this as best I could and am off 1/32" on the vertical and horizontal axis. I am hoping that will be ok?
Welded on some 1/4" flat bar fins to the back of the hub for more contact surface
Notice how I keep the pictures tight on the subject as to not share how messy my garage is?
