Haha, that's just an explanatory diagram but I imagine many bots look roughly like that xD

Ah well I suppose I'll give my table-saw a go then Relentless!

Why not? If the blade isn't to worn out, it will go trough like a good knife trough butter.

Only thing i would say about table saws and hdpe is that it has a tendancy to wander. It's either a two person job to keep it straight or i find it runs better with a couple of pieces of wood under it (just 10mm runners)

I use a jigsaw with a metal cutting blade and a router for all the groves and angles, works well

I use a circular saw with standard wood cutting disc

I clamp a straight edge (bit of 2 x 2 wood) on the HDPE and run the edge of the saw against that. Gets a nice straight cut
It does create alot of swarf (not sure thats the right term for HDPE but you get the drift) so watch for that.
I also have a chop saw for wood that comes in handy for short cuts
I find hole saws and HSS drill bits work fine as well

For the antweights the pieces are small enough to clear the cuts on a bench grinder (with a light pressure to avoid too much melting)
