Easy runner fix

Every sailor should carefully inspect his runners after sailing not only checking for edge quality, shim tapes etc. but also for eventual delamination. It may happen that runner body exposed to extreme loads during sailing will delaminate from steel. Above picture represents this situation. You can see a very tiny  gap between carbon flange and blade.  If we fix it the runner it will be fine, if we continue sailing the water will be absorbed by the wooden core  and body will begin to swell. 

Here is quick and easy solution to fix it.

First things first. I use Dremel tool with approx. 1mm thick steel cutting blade  to cut slot between blade and carbon flange. 

I make a fine slot along almost full lenght of the blade making sure cutting disc stays in contact with steel at all time. This way I keep big outside portion of the flange untached. The depth of the cut is usually not more than 2-3mm.  

This produces 1mm slot. If you are sure there is no moisture in the runner you can proceed to the next step otherwise let the remaining  moisture escape by keeping the runner in room temperature for couple of days.

Needle and syringe will be your next tool to fill the slot with epoxy. Make sure you get slot nicley filled. After curing trim the excess of epoxy and the runner is ready to go. I add black dye to epoxy to blend the fix into body.

After this fix I never had the runner fail again.

Take care of your runners at all time. Short glance costs nothing and saves a lot of problems.

If your runner  unexpectedly doesn’t  nicely snug into chock any more it may be too late for this easy fix and new tutorial will be needed. I hope not.
