At work (set construction for theatre) I often find I need to put a large angled hole in a small piece of plywood. We have one drill press in the wood shop and another in the metal shop. The bed of the newer one (in the metal shop) can tilt, but there are still the problems of needing a salvage bed (usually about 2 inches thick) for the hole saw to bite into.
To solve it I made this thing in ten minutes. I can change the angle to a wider range than with tilting the bed, and is faster to re-set. I have 22.5, 30 and 45 degree “ramps” ready to be slapped down and new angles are two mitre cuts away (I have found it works better to nail the triangles to another board and then put on the salvage bed). It clamps down once the piece is aligned correctly. The offcuts are much easier to get out with the air gap. The best part is I don’t need to worry about getting sawdust in the coolant.
Sorry for the blurry first picture, I only had my camera phone.
