My question is about stand practice when cutting keyways. I know I can make it work, but I want to make it standard, if possible.
Key stock is square. So, using 1/8" key as an example and cutting a keyway in a shaft and a gear, what is the point of reference for the depth of the keyways on the shaft and on the hole in the gear? Seems to me that it would almost have to be at the center of the keyway on the surface of the shaft or hole. But I would like this confirmed.
If this is correct, where and how much additional allowance should be provided to allow easy assembly and interchangability?
Also, how much allowance is normally provided on the width of the keyways?
