Poorly machined clutch plate

Look closely at the four counterbores. They should be cones, but they are polygonal. This is due to chattering of the tool.

Skywatcher sent me a replacement with a new design. They went with standard socket head cap screws and straight bores in the plate. I have yet to install this, as my locktite solution is holding.
