Venting my eps veneer board

General Discussion
1

I tried to put the same vent plug I used for my hollow in my

eps board and when I went to back the screw out the insert came out. Any one have any ideas?

Drill the hole twice as big (diameter). Fill it completely with epoxy and shredded glass. Drill a hole down the center of the epoxy plug (original diameter drill bit). Make sure the insert is clean and the screw moves freely, epoxy it back in. The oversize epoxy plug your insert is in should be a lot harder to pull out, glass it for overkill.

be sure to wash the instert in denatured or something to remove the oil that is left from when that thing was made…

on a side note i’d be sure to use an Oring… water can make it down threads…

looks good.

Thanks guys, that makes sense. I think I am going to fill this hole and cover it

with my logo. I wasn’t happy with the location any way. I want to move the

vent to the tail area so that it won’t be in the way. Do you think the location matters? Will it still work if it is all the way back at the tail were there is less volume?

I didn’t mean to drill a new hole. Just drill the current hole twice as big. I’d leave it at the nose, there’s no reason why the tail shouldn’t work fine though.

I thought that it might. Ive gotten in the habit of squishing some old way around the threads. When I thread it in the extra way forms a clump around the screw. I mold this around the screw and know that it must be watertight. (its a lot easier than it sounds)

Hola Marke!

You’re suffering the same as I did when I add my first footstraps inserts to my sailboard. I drilled a round hole, filled with resin+chopped glass, let it cure and drilled the smaller hole for the footstrap screw. When tightening the screw, the whole resin bed separated from EPS foam and started rotating.

I had no more problems cutting a square or rectangular hole (4 drills at the corners+razorblade between them) instead a round hole for the resin+chopped glass bed, because the 4 flat surfaces of the pack avoid rotation and separation from the EPS.
