cutting equipment

If it's good for cutting wood, it's good for HDPE. I wouldn't bother with a scroll saw unless you want to do a lot of curves. Bandsaw could be useful but it will only be good for smaller pieces. Table saw is another option or even circular saw.

What Gary said ^ Anything that you can use with wood with work with HDPE. But don't try and rush it with the thicker stuff because you'll burn your tools out.

Hysteria's shell was cut using a tablesaw for the thin stuff (12mm) and a jigsaw for the thicker stuff. (15mm & 12mm) Drills with go through fine but they will struggle to get initial purchase on the surface, a steady hand will help you there or use a scriber or a knife to mark a dent for the drill bit to fall into. Any if any channelling is needed then a router will work fine.

All in all, just be careful and know your tools limitations and remember friction causes heat which will melt the plastic and gum up your blades if you're not too careful.

Oh and whatever you do, make sure you cut the git outside because it is an arse to clean up, it gets in your carpets, clothes, dinner, cats, everything. Best place to do it is in the house of someone you don't like.
