|What's your best method to create reproducible round or arch cuts in styrene sheet?
I've been cutting the styrene sheet square, drawing the arch on with a pencil, then filing it into shape.
This takes a lot of time and doesn't create very reproducible parts.
I've also seen guys who print out several copies of a arch shape on paper, tape them to the styrene sheet,
then use an xacto to score a couple of passes freehand based on the paper pattern then snap to shape.
This seems like a decent method.
But I ran across one of these tonight....
Circle Cutter - On eBay
It's basically a plastic compass with a blade on the end which for styrene I'm wondering if it would be enough to score and snap.
Anyone have any better techniques?
