get the “Essential Surfing” book… photos will help a lot. the way i learned (when doing thrusters) was to do one fin at a time, doing all three at once is crazy when you are new… set EVERYTHING (scissors, squeege, rope, precut cloth, brush etc.) out before you start in neat stacks. i even make sure my glass is pointing the right direction so when i pick it up (use a sticky gloved finger in the middle near the top, never touch the edge or it will fray) i don’t have to try to spin it or adjust it). i usually tape a bunch of news paper over the bottome of the board about 6" infront of the fins and lay everything out there. the newspaper keeps the drips from my gloves from getting on the board… the less resin you get on the less you have to squeege/sand off…
i use 7 stands form a 24oz sheet for rope for thruster sets, more for twins and singles. first soak the rope and then ring it through your hand a few times, then lay the presoaked rope, on one side of the fin starting about 1’ infront of the fin, cut with scissors about 1" behind the fin , lay on the other side of fin again about 1" infront to 1" behind, cut off the knot that you tied to keep the rope together. then put on your 6oz precut sheets.
make a templet and cut all your 6oz side sheets the same, i attached a photo of a fin with an orange line around it, the orange line is roughly the shape of my templet. when you lay the templet on your 6oz cloth make sure it is 45 degrees to the grid of the cloth, this way the cloth is stratchable when are putting it on (when i learned this i was shocked at how much it helped)
hotcoat the bottom and after cured flip the board and hotcoat the fins with fins pointing down…
there are so many tricks even if you read them all you still simply need to do it a bunch and get your own system.
try using uvcure resin, it is nice to have a lot of time to get everything all nice and clean.
fixing broken fins is a geat way to practice…i attached a photo of a rin repair, bofore sanding to give you an idea of what your shooting for…
i would bet there is tons on this in the archives.
good luck.
oh yah, another trick i use is to put 3 or 4 disposable gloves on each hand. that way when a glove get too messy you just pull it off…
