HDPE for Vavuum Table
I am going to either build or buy a small vacuum table soon and am considering making one out of HDPE. My concern is how porous is this? Will it leak air bad? I am planning on using a shop vac for my vacuum. Perhaps 2 if need be due to size. I would like to make one that is 12" x 24" and use is for cutting and engraving plastic sign material. I will bemaking this 2 zones hence the 2 vacuums each of equal size.
Any input?
Thanks
Dan
