I scavenged some slabs of perspex (25 mm thick) from a shop that
went out of business. One had a groove cut in it. I guess that
this was made with a plunge router. Has anybody tried this?
I once cut 6 mm thick perspex with a jigsaw, using the finest
blade I could find, but it still made a rough edge.

We used to cut out the perspex scratchplates for Hayman guitars and
basses in-house on a router table (spindle-cutter?). The standard
single-flute cutter tended to burn the perspex through friction but a
multi-blade cutter worked well. I think the optimum was a three-flute
cutter but I don't remember too well as it was another bloke who did
that job! And it was an awfully long time ago.
