Waterproof CNC Router Cutting bed

[Maxakarudy]

This is my router bed, 3mx2m in 19mm foamex, I cut a grid with 100mm centres for easy reference to keep things square, I cut a lot of sheet material 3-25mm, I prefer to screw things to the bed, in the slot 5mm deep, so there is liitle chance of movement of the panel and clamps are more bulky and can slip.
My machine has a vac bed, however I've learnt of the years it's not 100% reliable to stop movement of the panel, 1 screw up and it's all over, I cut quite a bit of aluminium sheet with mist coolant so don't use the the chip collection system, I do use it on dry materials like perspex & mdf.
BTW I conterbored it to the aluminium slats with Tec screws which are about 10mm from the cutting surface, then milled the bed flat



I have a piece of 19mm foamex 1000x500 I can get it delivered for £50 if you are interested
