Hi,>>> Gonna install the leash plug tomorrow, how to keep the plug in position? > Thanks for any input.>>> Regards,>>> Crabie …never had that problem…sawhole, then lam resin/cabocel/fiberglass mix(really thick)mount the plug inplace…it should hold position on it’s own.Herb

lam. resin? i have been using sanding resin. is this a bad idea?

lam. resin? i have been using sanding resin. is this a bad idea? …it can be if the plug shrinks away from the resin.The rising wax can cause delam to your box,not all the time ,but once is all’s it takes. …here’s a better Idea!..use lam to set your plugs,and boxes,then go back and brush/fingerwipe a little hotcoating resin on it.You can do this right after then lam gells.Herb

You wouldnt glass over the adhesive, would you? Also, do you think you would do fin plugs with it too? The reason I ask is because in one of my boards the fin plugs (FCS) and the leash plug are held in this circle of bright white stuff…doesnt seem to be any kind of resin used…

Hey Cleanlines, Does the silicone adhesive works with eps foam? I m afraid it may melt the blank. Regards, Crabie

Herb: I believe what cleanlines is describing is 3M 5200. There are several other 3M products in this family, some with faster drying times, all are legendary in some sailing circles. 5200 is 24 hours to full bond. Walmart sells it at about $5.95 for a decent size tube, also comes in caulk gun size. I’m interested in hearing this too, seems that someone about 3-4 months ago mentioned setting FCS plugs like this. I use it on sailboats as a bedding compound for backing blocks under cleats etc. The stuff is tough, don’t know about sanding it though. Cleanlines, is this the right stuff here? 3M 5200?

Cleanlines, is this the right > stuff here? 3M 5200?>>> Tom S. 5200 is a very aggressive polysulfide based marine adhesive. It is sandable after a full cure. The original formual was 24 hours to full cure. When I ran the boat yard we would use it for bedding any fitting that was never planned to be removed. It is semi-pliable even in its cured state. So it may not be the best for base rigidity when setting your fin plugs. But to be honest I have not tried it in that application yet.

Aloha, When using a fin box I learned a neat trick from a local builder on Oahu. After routing out for your center fin box, I drill a 3/4" to 1" hole about 1/8" from the back of the finbox centered on the stringer. Then tape up the deck and when installing the finbox, you fill the hole and set your box. When it is ready, you simply remove the tape from the deck, drill a 1/4" to 3/8" hole centered through your “plug” thats it! It works great and I’ve never had any leaking problems, plus I would assume it is much stronger than your conventional leash plug.

I’m sure the leash attachment is strengthened with this method, but I think the surfboard would be weakened. The tail end of the fin box is the weakest place on a surfboard. The front edge of a finbox is next. Since the front end receives more force, that’s where lots of boards break. At the rear edge of the fin boxes most boards stringers are only 1/4" thick. Its also a place where you’ve removed glass and foam, and spliced them to a piece of plastic… a weak spot. What you’re doing is removing all remaining stringer in a splice area. The tail breaks off the board. But hey, the leash is still intact. Good luck.

Yep thats the stuff and I like it a lot…It is somewhat less ridgid than resin but to me that is why it bonds so so well.As for the base flex thing I don’t think that it is big factor (but then again I am not a fin expert).It sands down ok if you use a course grit like 60.It will work on both eps and poly foam.I have to admit that I have never tried to gloss over it with resin…that may be a no no.Acrylic speed spray works ok.
