Thanks for the reminder, Brad.

On the two machines in the last video the ration is .625 on both, 10/16 or to reduce the fraction 5/8's...... if I was to switch the gears I would get a l.6:1, a little faster than the fast gear on the Boss. I am just thinking about pegs. I wonder what the grunt factor would be turning a 1-1/2" bit in white pine at that ratio?

The handle lengths are and interesting concept, I find the fixed handles to be very comfortable, much longer and the ergonomics is off.

Brad, what does the diameter of the gear contribute to the equation? Say a 4" gear with an accommodating correctly sized gear, to hit a ratio already known , either bigger or smaller?
