Thankyou.... Youve opened my eyes.... While i was thinking my instal was too low- thinking i needed to keep sanding down to remove the colour tabs, in actual fact my instal was too high- Therefore i actually needed to keep sanding down to get the tabs flush with the bottom of the board- all the while I was thinking it was just to remove the colour tabs... Not really thinking about what I was doing/or why... Def going to try sitting the boxes a bit lower... Ensuring the top of the box (not the raised slot rim)... Is slightly lower than the foam itself....
Just wondering if the OP dealt with this problem? Was it a case of setting boxes too low or too high in the end? I notice the same on my last board, tiny bit of weave showing around the tabs
Hey Helter, yep seemed to get a better result now that I am setting them slightly lower, when I say slightly, I mean slightly! I think the instructions said something like so the box sits 1/32” below the foam... not sure How I could measure that, so Im having them sit a smidge, like 1mm below the foam, seems to yeaild a better result!!
Cool thanks for replying. I was worried I was fitting mine a bit too low, but I am definitely no more than 1/16th below foam. I am also fitting them post lam now, just seems a bit easier and more forgiving. Not sure if the pic below shows it clear enough, but if you look carefully you can see weave around the tab closest to the camera. Bloody annoying! Wish I knew how to avoid this, still a bit confused (As you were once!) whether its a case of setting boxes too deep or not deep enough. Will keep experimenting. I did get one board where this didn't happen but I didn't do anything differently so it seems a bit like luck to me (being a novice backyarder!) AS someone else said, it probably doesn't matter much in the grand scheme of things, I just hate seeing anything like that, I don't spend hours and hours and hours to see unsightly shit :D
Actually this works better.....
Hey Helter, yep that photo is exactly what ive been getting... i did a repair the other week where i routed out the busted box, did a foam insert and re routed plug the. Re set a new plug... i did this with the ‘slightly’ deeper setting that I wanted to try and it seems to come out much cleaner... have a couple of boards to do so going to go with the slightly deeper setting and see what happens!! Im hearin ya.... very frustrating!! And a bbit co fusing as to whether your to high, or too low!!
Cool, good luck! I agree with others saying go deeper, you can always float it up a bit. Trouble is my first few boards were like WAFERS, at 1/32 below foam, there was about 1/16th of foam in the bottom of the box before the glass!! scary 5hit :D
Helter, that looks like a small air bubble. Do you cut slits into the cloth to allow it to drape better over the proud parts of the fin box. There is a tendency for wetted cloth to 'tent' over a fin box as it is being pulled tight around the box? If I get bothered by one I open it up and fill it in with resin.
Saltbush, I think too deep is part of your trouble. I would try setting your router on practice pieces until you can get it spot on. If I got too deep I add cloth and resin in the holes to bring the boxes back up to flush with the surface. What are you using to sand open the boxes? Coarse grit hard flat pad?
Be safe, have fun. -J
Yep hard pad, coarse grit to knock the boxes down!! Ok, give me an idea where in relation the surface of the foam (as in the bottom of the board) should the top of the fin box be sitting, not the top of the tabs... the top of the fin box itself!!?
Hi JR, thanks. I am not sure its an air bubble but it does look like it. There is no tenting. these were fitted post lam, with glass cut to size of socket, then a football patch over, all pulled nice and tight with fingers and squeegee. I suspect you're right and may try setting them a bit shallower so they stick up more and i don't go down so far when sending.
What I find if setting a bit higher is the tab needs more sanding to get it back down flush with the board, therefore exposing weave around the tab itself, whereas the less sanding to be done on the tab, i.e just taking the top off of the tab means less weave / less chance of exposing weave...
