the paddle after routing
The paddle has been routed! A 1/2" radius round-over bit, in a Hitachi M12VC 2-1/4 HP Router, was used to turn the square profile shaft and t-grip into a circular profile. A palm router would probably have been easier. A router table would have worked even better. Then next step will be to clean up the work with the DeWalt 5" Orbital Sander.
