Preface: I struggle with epoxy cut laps on EPS. I’m always pulling ‘beads’ and my cut laps using epoxy resin are as smooth and even as Donald Trump (oops!). Just reading my ‘The Surfer’s Journal’ 25.4 and the article on Randy Rarick restoring classic but well beaten boards back to their former glory. One image in that excellent article shows the cool tool used on what I am sure is a poly/PU cut lap. Think this would help my epoxy/EPS cut laps? Maybe I should ‘baste’ the rails before taping the cut lap line?
I’ve done them with a similar tool (early on when I struggled with them, it allowed me to focus more on perfecting other aspects of the build process). I now fined that just letting the resin cure a bit more and flipping up the tape and trimming with a razor is cleaner and easier. This is the way most are done.
To make a tool is super easy. I can post a pic later of the one I made if you need direction.
Also… If you use the method above on the deck side cut, when you lamed the deck you would be left with a dark line from scoring the foam (this may or may not be desired).
I always get a couple and I just cut them out. So, I go around the lap with a sharp razor and try to get it to “zip” along the tape. Sometimes I get a little high and get a bit of tape. I go back around the board and clean these up.
I did a board recently that I did a green lam and I used blue tape. I have a couple of slivers of tape I simply did not see until I got the board out in the sun. :( The board rocks, so I don’t care.
