Squirrel:
Was this on the input side of the Delwalt? If so our solution was to make a adapter plate on the delwalt side, it has 4 small holes which match the 1st reduction planet gears, eliminating the need to bore out the gear. On the motor side, it's drilled to accept the motor output shaft. we than have a setscrew. It adds about .5 to the overall length of the system, but no mods to the gear were required.
