I am in the process of designing a circuit board with a 2 inch speaker. The board will be inserted into a PVC enclosure with a 2" hole in which the speaker will sit behind (The hole in the case will be seen on the front of the unit with the speaker behind it).
I need to make several hundred of these. In my attempts to drill with my drill press, the plastic melts where the bit edges are. :cry:
Is there a way this can be done? I tried a 'hole-saw' bit as well as a wide adjustable bit. Are there "companies" who can do the drilling for me in a professional way? I guess my question is - can my plastic PVC case be reworked to add a 2 inch hole without looking bad so it can be sold in a product?
Thanks for any advice. I am willing to run down to the basement and try some of your tips.
