30mm HDPE makes a nice stable bed and you can cut a grid pattern to make it into a Vacuum bed. I bought a 10x5 sheet for £500 so if you get in touch with plastics supplier you might get a small piece or cutoff piece cheap enough.

Ok thanks, that is interesting, YM of HDPE is only 0.8, how much support did you have under it, or what was the clear span? I guess we are only talking about supporting the mass of the part being machined and the downward force of the cutter, this is probably minimal, like to take a punt on what this force is?

Looks like an 8x4 sheet of 25mm SRBP is £380, this would give me enough for the base board and two spoil boards.
