In the tropics the teak around the cleats on our toerail has split and we posted a note on a Cruiser’s Forum about it. I’m adding this post with further photos for those who have asked about the issue.
The issue was caused by water getting between the teak toerail and aluminium spacers which then corroded and expanded, splitting the wood. We decided to try to repair it ourselves, without having the cost of replacing the teak.
First we undid the nuts from underneath the cleats. These were under the headlining inside the boat. Then the backing plate was removed. Back on deck we used a lever between the cleat and toerail to force it out of its seat.
We then cleaned up the teak and old holes, opened the splits slightly and sanded inside. Then cleaned everything with acetone, masked up around the splits in case of resin oozing out and staining everything, before injecting resin into all the splits with a syringe and then clamped it tight with 2 g-clamps.
When it was dry we sanded the whole area to remove any excess resin and smooth the teak. Then we used silicon sealer inside the new holes and around the edges and also around the edges of the new spacers, again masking up the cleat and teak around to stop it spreading.
Finally we slotted the new spacers onto the posts and pushed everything back into place, tightening it all up and removed all the excess sealer, making sure that any delrin that was visible was covered in sealer to prevent it being degraded by UV.
