I started manufacturing my own "small" 720 mm x 720 mm vacuum farming table. Vacuum box is now ready and glues are drying. Now I will start making brackets for holding that plactic sheet.

Hole spacing is 50 mm and size 2mm for each hole. My subcaontractor advised to use 1 mm holes, but those are too small for my drill :/.
