The 10 mm is the grooved and drilled version and gives an excellet coverage of expoy on the underside of the layup. But on the 5 mm without any grooves or holes the expoy just gets in about 40-50 mm from the outside edges. I'm about to make large boards with the 5mm. How would you recommend I go about and modify the core to get good coverage? I'm talking about 4 square meters so e.g. drilling every 25 mm would be preeeetty time consuming.

You don't need to drill though, you can just punch a hole with a screw driver or anything. For 4sqm, I'd probably get a plank if wood and put some nails through it along its length spaced 40mm apart. Then you can punch 10-20 holes at a time without having to measure spacing. Edited 9 Years Ago by Hanaldo
