I'm doing a project where in I am casting hard plastic (not sure what kind) and then need to drill into it at fairly precise angles. The pieces are more or less flat, about 3/8" thick, and I need to drill 1/4" holes in them lengthwise to insert some 1/4" acrylic shafts.
I would ideally do this with a drill press but the pieces are kind of long, I do not think they would fit under the press. I have made a test hole by clamping a piece to a table and using a power drill held parallel to the table, but I wasn't able to be quite as accurate as I'd like.
Anyone have any good ideas on this? I'm thinking a kind of horizontal jig, but I don't see very well how to make it.
