    Re: Cutting a hole in a lens board?

    Students in a machine shop class at our town's high school will cut a precise hole in my metal lens boards for only (a donation of) $10.00. Definitely the way for me to go in the future.

    That's a great way to go, Greg!

    I have a circle cutting guide for a router, and if set up correctly, makes really nice holes in wood!!!

    The bit inthe Circle Cutter can be replaced with a metal cutting bit from Home Depot.

    I bought a pack of 10 1/8" shank bits for drilling and routing circuit boards (I think) off fleabay that cut aluminum like butter. I think I paid about $12 for the pack. There's a lot of CNC routers out there, so there's lots of specialised bits you can buy that also fit Dremel rotary tools.

    Re: Cutting a hole in a lens board?

    Since I'm fortunate to have a milling machine, I cut my lens boards with a boring head. Perfect holes, any size, very quickly. Before that I used a circle cutter in a drill press. Before that I used hole saws in a hand drill. Before that I used a jig saw. Before that I had someone else cut them.
