Undersized But Ok
The specs say 5mm to 6mm. The 5mm hole is undersized (4.9mm). The motor shaft is 5mm. A small difference but out of the bag it did not fit on the 5mm motor shaft. I did not have a 5mm drill, but I did have a 5.12 mm drill so using a drill press I enlarged the hole to 5.1mm. In this application a focus motor for a telescope, the oversized hole seems acceptable.What else can i say. it is a nicely made coupler with the only flaw being the undersized holes. If the holes had been to spec then five stars.
