Vent/Leash Intallation

How to install your Clearwood vent and leash plug sets.

The following post highlights the installation of the vent/leash plugs for venting and tethering hollow wooden SUP’s and surfboards.

The vent plug with brass insert and a leash plug with a stainless steel pin are for use in venting and tethering hollow wooden surfboards and paddleboards and are pictured above. The brass vent insert and the stainless steel pin are provided loose, which means you will need to work with an appropriate epoxy product in order to adhere the brass vent insert into the wood vent plug and the stainless steel pin into the leash plug.

You will see on the vent plug that the brass insert has been pre-threaded into the wood plug from the bottom of the wood vent plug.

This has been done to assure proper alignment when the brass insert is threaded into its center hole. You can remove the brass insert from the vent body and carefully reinsert it into the wood vent body after you have coated the inside of the hole with epoxy resin/hardener. I have found that the best way to coat the center hole in the wood vent plug is to use an artist brush other small, flat bristled brush to carefully brush resin/hardener into the hole while gradually threading the brass insert into the center hole. Care must be taken to not over apply the epoxy/hardener. Over application will create excess epoxy which can flow onto the inside of the brass insert and make it difficult to screw in the machine screw with “o” ring that acts as the seal. I lightly coat the inside of the wood vent plug hole with epoxy/hardener, then with epoxy/hardener that has been thickened slightly with silica dust, apply a VERY light coat of the thickened epoxy/hardener to the inside of the wood hole that the brass vent is being threaded into. This slightly thickened epoxy/hardener mixture will provide a positive seal around the thread and lock the brass insert into the wood vent plug. You can also cut a small bit of masking tape which can applied to the threaded hole that accepts the threaded vent screw. This work must be done carefully to make sure that the threads that accept the machine screw do not get contaminated with epoxy. 

When the inside of the wood vent block has been saturated with epoxy and coated lightly with thickened epoxy, thread the brass insert into the hole in the wood plug. This is done from the bottom of the wood plug. The brass insert is threaded up into the wood plug using either a wide screwdriver or coin until the top of the brass insert protrudes slightly above the top of the inside lip of the wood plug.

Installing the stainless steel pin into the pre drilled hole in the wood leash plug is a two step process. I recommend that the inside of the leash cup be coated with three coats of epoxy/hardener prior to installing the stainless steel pin. It’s important to finish and protect the inside of the leash cup and this is difficult to do once the pin is glued into place. The leash pin is epoxied into position as the wood leash plug is epoxied into the board

Blocking must be placed on the inside of the board to accommodate the vent and leash plugs. The vent plug must be center bored to allow for air passage through the vent. The vent block can be slightly deeper than the vent plug which will allow the vent plug to “seat” against the bottom of the internal vent block. The blocking for the leash cup should be securely attached to the board due to possible extreme loading on the leash cup.
