Trevor,
I would just like to comment here: 1/32 of an inch spacing on the CNC woodwork machining to drivers ?
Honestly, as a professional woodworking cabinet maker, we need that type of spacing on veneer products to metal parts. If you ever wish to change out a driver part, you will not be able to remove it with tighter fitment man. We are talking .031 inch spacing. It's perfect in real terms.
