I plan on making a clock out of acrylic (about three of them) and need advice on cutting acrylic, mostly circles, though. The site I plan on buying the clock inserts and acrylic from has these things called "Forstner" bits and the price is a bit higher then I want to pay for a bit I may only use for this project (about $12). And I'm wondering what would be a cheaper way to go about cutting circles in acrylic? Drilling guide/pilot holes that are at the diameter of the circle I need cut and using a jigsaw to cut the circle out? Or is there a better way to go about doing it?
Any advice on cutting acrylics would be awesome, too.
