Repairing a Stripped FCS Finbox
HTML-код
- Опубликовано: 11 сен 2024
- Ride your board into the sand? Hit the reef? Over tighten your side fins and stripped fin box? Either way you are "screwed" because your side fins might fall out!
This is a quick fix that will work if you do it right. If you mess, up it's easy to start over.

Did it. Worked like a charm. Many thanks for this concise and accurate vid.
Glad to hear!!! Have fun out there!
I use a method, which is similar, but I think is easier because it requires less tools. Here it is:
Before starting, go to the hardware store and purchase a 1" or longer 10 ANC x 24 screw (24 TPI). TPI stands for threads per inch. I find it much easier to work with a screw that is longer than your standard find box screw. NOTE!!! This screw size is for a Future Fin Box. An FCS Fin Box might use a different size screw!!!
Step 1: Remove the fin.
Step 2: Tape off bottom of stripped screw hole you want to fix so the JB Weld does not leak out the bottom.
Step 3: Mix JB Weld Part A and Part B according to the instructions. Fill the stripped threaded screw hole with JB Weld.
Step 4: Put the end of a paperclip, a pin, or something similar into the threaded hole and slowly move it around to "work out" any possible air bubbles in the JB Weld.
Step 5. Take the 1" or longer 10 x 24 screw that you purchased from the hardware store and lightly coat the threaded portion with Vaseline or some other type of grease that does not flow at room temperature.(This is to prevent the JB Weld from sticking to the screw as it cures.)
Step 6. Thread the 1" or longer 10 x 24 screw into the stripped threaded hole. Thread it all the way down until you can see the end of the screw barely push on the tape you placed at the bottom of the screw hole.
Step 7: Let the JB Weld cure for 24 hours. Remove the screw and you are finished.
Doing this tomorrow, thank you for the clear instructions. Cheers!
@@Justin-ig7sg how’d it work for you?
Awesome! I gotta try this. Fingers crossed!
It worked! Thanks!
I have old FCS1 finplugs and i just drilled new holes on the opposite side with a 4 millimeter drill. It worked out fine and I can tighten the screws again. So no need to buy jb weld or something similar... I don´t know yet if the new holes will pull water but I did the repair job on my riverboard which is pretty destroyed already anyway so I thought its worth a try.
that can't be watertight
I put superglue on the screw put it in loosely and when its dry screw it our and back in, if the hole is totallu too big Iuse a bigger grub screw
Thank you!!
good man
I'm not sure it would work, but instead of using Epoxy, wouldn't be possible to "melt" some white plastic (lets say...pvc bottle caps?) into the fin screw hole and them proceed with the drilling? Or wouldn't it attach to the hole?
It’s possible. Just don’t inhale the fumes of melted PVC! Worst case you can always drill it back out. However, you don’t want risk melting part of the board if the plastic is too hot.
@@JasonLeeCalifornia Thanks. I tried some Regular Epoxy (not the naval type, but the one with two-tubes ready to mix) on a future fins box but, for me, it didn't worked. Haven't tried the melted PVC yet. I fixed it by getting a wider screw and carving new threads.
@@quimlima Yeah, that's the easier solution is to size up in threads. JB weld is actually better for this than epoxy. Epoxy probably cracked but glad you are up and riding!
Can the hole be filled with solarez instea of jb weld?
I wouldn't recommend it. The weld seems to work the best and is much harder which is why it can be tapped.
Can you take the screw out after or is it stuck
You can take it in/out. Just make sure it's the epoxy is cured.
Does it matter what epoxy you use
I'm using regular JBweld but the marine stuff might be beter: www.jbweld.com/products/marineweld-twin-tube
I’m thinking of doing the Marine grade. I just did JB epoxy clear and it didn’t hold. It felt like gummy bears. Not sure if it’s because of the temperature here in SF. I set it for 24hrs. And i was not happy with it. So I’m off to the store.
God that looks annoying
