Porous MDF waste board?

[AdCNC]

As far as i am aware all they do to the mdf is take the surfaces off the mdf making it less sealed.

Ptjw7uk.. If I remember right, the mdf was placed on top of the vacuum table, but allowed the air to pass through it.. The cnc was machining kitchen units out of 8' x 4' boards.. I do remember being told that the mdf was available off the shelf but as I said, cant seem to find it now I am looking..

I wish you well but I would caution you to be careful as you could leave to much open surface and loose most of the vacuum.
Most vacuum systems are designed for specific jobs ie mass production etc and care has to be taken or it will fail.
The other possibility is if you have a high throughput pump then it could withstand a fair amount of leakage etc.
edit - just had another thought after rereading post, If the 8x4 was on a 8x4 mdf and the vac table was 8x4 then there would only be leakage when you cut through.
