Step 14: Installing the Leash Plug and Vent Plug

Vent Plug
It is very important to vent this surfboard, because the chambers are filled with air, when the temperature changes the air expands and contracts. If the surfboard is not vented then there is no place for the air to go and can end up damaging the surfboard, either with delaminations or bubbles appearing on the board.

The vent plug that I am using is actually dual purpose, there is a built in Gore-Tex membrane that will automatically vent the surfboard and also the plug can be unscrewed so you can vent the surfboard manually.

I made sure to think ahead when chambering the board to route a path to the rear of the board so the entire board could be vented with one plug.

To install the vent plug a hole was drilled and the wood removed, because there is a void in the hole that connects to the chambers, roughly sand the vent plug and wipe down with acetone. I used some epoxy putty to seat the vent into the surfboard first. Then I can fill in the rest of the empty space for the vent with liquid epoxy.

Leash Plug

The surfboard needs a leash plug so a leash can be attached and I installed this the same time as the vent plug when working with the liquid epoxy.

There are a few different types of leash plugs: installed while glassing the surfboard, ones that include an automatic vent and ones installed after glassing. I'm going to install the leash plug after glassing. Where the leash plug was going to be installed I did not chamber that area of the board.

To install the leash plug is simple, drill and router a hole for the leash plug, rough up the leash plug with some sandpaper and wipe down with some acetone, mix up some epoxy (add a thickening agent like Cab-o-sil or some baking soda) and fill the hole with some epoxy, set the leash plug into the hole. Let harden.
