Kitchenaid stand mixer to Milescraft 90 degree drill adapter

Prototype for coupling the Kitchenaid stand mixer attachment hub to a Milescraft 1390 90-degree drill adapter.

This piece failed fairly quickly, with the set screws getting forced back over their threads and no longer gripping the Milescraft shaft. But I think if you just screw the set screws directly into the tap holes rather than tapping the holes first the fit will be tighter and more long-lived. The newer model is very similar and has lasted longer so far with this approach.
