Bud, that is impressive ! I must see more, will there be planes offered ?
That is one of the sweetest machines I have seen is quit some time, and it looks like it is capable of doing much more than you have shown.
The disk hub looking item at the back of the spindle, is this a Brake for holding indexing ? Is it phumatically operated ?
Its quite obvious you have put a lot of work into this machine. I would love to see more about its funtion and abilities.
Edit - after looking closer I can the disk brake looking piece is the pulley hub.
