Lots of options here, so I need to start experimenting.
The curves will be fine, and I intend to make a jig.

The options I have are now many:
- Heated wire -- need to locate proper wire.  Power
        supply etc is easy to get, but will need to
        experiment with settings.
- Router/dremel with appropriate bit -- easiest to
    start with since I already have one.  Two bit
    options are now available to me.
- Jig-saw or equiv -- need to find the right bit.

I'm avoiding sanding, etc cause I will be making
multiple copies of a piece and want to make it a
repeatable process vs. say, an art. :-)

Thanks for the options everyone -- I now have my
homework to do and will let you know what the outcome
is.

Cheers,
-Neil.

I have used dish soap as a coolant and lubricant when cutting Plexiglas with
a saber saw or dremel tool. Works great and keeps your hands looking younger
too.

Hi Neil, ring around the local signwriters,
they almost all have CNC flatbed machines set up
for acrylic which they do all day every day.
If you take in your acrylic and a decent drawing
they can cut your shapes neat and exact in
whatever quantity you need. The operator is
usually skilled enough to whip up basic geometric
shapes in minutes, although they may ask you to
leave the job until off-peak. For a few small
pieces they'll probably charge about $10.
