re: Drilling/Tapping Acrylic Lenses
A good response by faster, and he himself knows he left some details out.
Having tapped many holes in metals and plastics...
* This will be tricky, since the plastic is thin (1/4"?).
* This requires bottoming taps, which you will have to buy.
* You will need to practice on a scrap. I would.
After practicing he may decide to through tap (easier, safer, and stronger) or through bolt. I might consider a cemented-on reinforcement ring and tap through that; it could look very professional, if the ring was well cut and edge polished, and the port would be stronger for it.
