ok heres a few choices …
i agree with dan about potential leak spots…
these days i do use commercially available leash plugs …
just make sure there is generous amount of resin around the plug inside the hole to seal where the pin is exposed and glass over everything …
prior to 97 everything was loop , but i had a glasser we called MR bubbles and his loops were shocking even tho they were pre moulded in a silacon rubber mould and all he had to do was place it on a wet layup and put 3 oval patches over the top with a slit cut in them and work out the bubbles around the edges he still couldnt get it right …
so for the sake of quality , i made the switch to standard plugs , once in , sand flat , tape then glass over , at least he could run a flat squeegee over a flat surface…
in this pic , 3 are just peices of fin panel and glassed on like a small fin and sanded to shape then drilled later after finishing …
the other 3 were done in this kool silacon rubber mould i had , the hole was pre done in the mould but not quite all the way through , the loops came out of the mould in the perfect shape with a generous foot , so they could be placed down and patches laid over with a slit cut for the loop to poke through , rovings and chopped glass were loaded into the mould dry , the mould was baked and then boiling epoxy was poured in so it ran through the glass real easy …
i would still be doing them , but i found loops just to dangerous as well …
so many times as i was loading for a big move and my foot was hard pressed against the tail on an angle , i slipped sometimes and as your foot passed over the loop , well it kinda hurt , bad …
only good if your have tail blocks …
i always wanted to use wood but never trusted the strength or seal , so when i see pauls one , im seriously impressed …
i was thinking if you want that 70s retro look what about drilling a hole through the fin , and just use the rope and sock trick , thats about as authentic 70s as you can get …
