Actually futures, fcs fusion, surf finz, o'fish'l or any raised fin box or leash plug system can be placed under corecork skins.
This was 2mm corecork and 4 oz fiberglass cloth vacuumed bagged over some future fin boxes. I was going to glass the bottom then sand but I wanted to check out how they would come out.
I will retape when glassing the bottom. Next time I will check out how final glassing then sanding prior to final coat of epoxy goes for me.
I sanded through the corecork to each box in 2-3 minutes with a flat palm sander and 80 grit sand paper. I will probably make some relief cuts over the 7 and 10 inch center box
I got them from a distributor to evaluate. They are nice. That distributor decided not to mees with them so I have no clue if they are even still manufactured.
I would send you some but you need the adapters to use the router with the futures jig.
Wouter, Charlie has been doing the vac bag thing for a while. 5 years ago he was what I’d call the “master”, and he was doing it by himself. My brother and I usually bag together to have 4 hands. The other thing he was doing was wrapping balsa around the rails, not making solid rails like a lot of us do. So many of his techniques are way more efficient and cost effective than most of the artsy stuff a lot of the builders are doing.
Charlie, are you still doing other kinds of skins? Every time I run into certain shapers in the water they ask if I’d do a skin for them, but I don’t want to say yes and then screw it up. I always say, there’s a guy in EB that you should try to contact. Then I may not see them for a while and it all goes in a circle again.
Man that’s tight work! Tried it one time only with a sup grip. I lost it and had thought I was in position with a laminate trimmer to “clean it up” but cut right into eps!!! Yikes. I call that an epic fail because next time ill put a dozen or so layers of tape over opening and sand it right off. But whatever technique you did worked sick! Looks clean and mean. What a seat for your box.
[img_assist|nid=1063984|title=Cork Tail Quad|desc=|link=none|align=left|width=293|height=640]We did one with ProBox on a funky quad that turned out quite nice.
Obviously post lam though.
ChrisP…What density cork are you using for your skins?
Haven’t gotten them in the water yet. One needs sanding and finboxes. The other needs deck lam.
Those pics I posted are BB30’s. Him and Drewtang seem to be the ones that have it wired… Diverse surfboards (IIRC, he posts here too… FeralDave maybe?) just posted one on the ERBB that looks SWEET! Comes in at about 4 lbs!!!
Take the work if you want it and I will help you do it. Most people run when they find out the vacuum bag total board skinning is $27-35 per foot, depending on width of board.
I have a new contract with an inventor doing composite work. I have to laugh to remember my goals in 1999 and how I am at a place I could not have imagined now.
I’ve been using the 1.3 and 2 mm from core composites in NL 20. …Definitely NL20. I made the mistake of using NL 10 and ended up sending the remains of the roll back (which they were not happy about, but super accomodating none the less). The NL10 is way heavier in my experience because of bigger holes between the cork absorbing more resin and I had more trouble with the resin draining through the glass into the cork, leaving me with pinholes in the deck.
I also recently started doing the bottom glass first to get a nice clean hard shell on the bottom foam, then the cork goes on the deck, then I sand the edges of the cork and do the top lam. I did one with 1.5 oz glass over the cork and with resin x it was bomb proof.
Question: If anyone has a great idea for getting rid of the hump on the edge of the cork I’m all ears. I tried cut laps, but that didn’t give me much edge fill. Cosmetically, I’m puzzled over this one.
