PEEL PLY Measuring out and cutting with 2 inch hangover of rails. This will be used for an exposed cork top lamination.
I use peel ply for vac bagging most everything except wood planks such as balsa. I use PEEL PLY for carbon fiber, kevlar, texalliumin, nylon, cork and probably would use it with veneers if I used that stuff.
Once cut roll up keeping in mind if you start tail or nose to unroll it when needed.
For beginers I recommend with a double layer of fiberglass cloth to take the length of the board and mutiply times 3(Three) for the total resin volume in ounces. The Peel ply will pull the excess resin through the cork. I am going to cut my 9 oz cup to 7 ounces to wet out my cork/fiberglass.
Securing deck with tape. Don't get too concerned with complex nose or tails issues. You can always cut and place nose and tail blocks if needed. I was able to wrap the nose and tail nicely and will see what happens when cured.
Review. Board is in vac bag. Side with inlet nniopple is clamped off and other side is 0pen with no clamp. HOOK UP VAC TUBING TO INLET NIPPLE AND SWITCH ON PUMP.
The opened end of the bag is 3/4 clamped off. Place a suction source(my festool vac) and place nozzle on breather cloth. Clasp opened part of bag around festool suction with one hand. Turn on festool suction to draw bag to vacuum very quicly.(< 30 seconds) Full disclouser- I stole this idea from Bernie(oneula) while watching him.
Suck down to about 80% total vaccuum, remove festool suction, clamp off tube completely, your main vac pum is still sucking. Pull slack of bag to make deck side tight as possible and rails bend to bottom.
Roll out flats then curves just to make sure things are adhering nicely.. Very necessary with veneer. Balsa planks and cork not so much But I do it anyways.
Thanks for this thread. As good as it is, I still need to find some time for us to get together and see the peel ply action up close. Bernie gave me a pump and bag, and I still haven't used it myself. I go home and do boards with him.
Did Dennis get in touch with you? He asked me for your contact info.
Hi Jason. Still recovering from two days on the outer reef and 2 days inside for 4 days straight of surfing. Probably next wed and thursday for the ns. Hope you are scoring some good ones too.
Here are some pics of the board for the vac bag project. it is currently third in line to be sanded then urethane sprayed. These pics are of the final coat of green room blue jug resin/west coast fast hardener that was brushed on like any gloss coat. Green room pours liked water. I didn't post past where I left off because it is pretty much just surfboard building and no vac bagging stuff. For the 9 people on this site who are interested in vac bagging I will post all the steps in my next project with different materials. Thank you for the PM and kind words. If you have specific questions feel free to ask. If you are on oahu you are welcome to come by for personal lessons/help.
Actually make that 10 people!!!!.I've vac bagged about 20 kiteboards using all sorts of lam combos and with varyong degrees of success I might add. Am thinking of doing both veneer and in cork in future so this a really good thread IMHO.
You probably are a MBA or Phd grad by now? I am stoked I am still alive!!!!! Come out and visit!!! we have a spare room all ready for you and your family.(are you married????)
Hey Charlie! I haven't used release film yet. Just peel ply then breather then in the bag. Suggestion for type/brand/thickness of release film?
Lately I've been GGing the cork on the bottom then with 4oz. S2 glass over. On top I use Palownia and balsa adhered with 4oz glass then 4oz glass over...and of corse deck patch of cork on top for traction! Excellent with no wax!
So...that's 11 baggers reading your posts?
Sounds like you have it wired Les. I really like the balsa bottoms and exposed cork decks. I just helped a sways friend do a carbon bottom and cabon/exposed cork deck. I will try one soon also. I have dusted off all my nylon and my next board build will be a nylon/exposed cork deck build. I have no clue how to get a hold of palownia shot of ordering a container full for cheap. Release film is usually green tint and its only purpose is to protect your vac bag/and breather cloth from getting resin on it. So you must throw your breather cloth away? I get peel ply and breather cloth and release film fromFiberglass Supply (Surfboards, Windsurfers, Kayaks, Canoes, Boats ... You will have cheap shipping. It is so expensive to ship it to hawaii. Sometimes the shipping of a roll is more expensive than the roll. I only use peel ply direcly to fiberglass(cf,kevlar,e,s glass,texalluminum etc AND CORK) Wood no need. Pic of peel ply coming off carbon. Not sure If I made the file the correct size but I tried.
I'll PM to catch up, but wanted to post something quick here that may be of help to yourself or others on Sways. It's a product called Compoflex, basically combines peel-ply and breather in one. Or if you are doing infusion they have versions for that as well, so instead of multiple layers (which is always a hassel) there is just one. Not sure how easy this is easy for you to get in Hawaii and it's a bit more expensive, but a time saver for sure. There's the usual problem of wrapping with complex curves, but it's not that bad.. If you're bagging top/bottom as one step you would just leave the sheets flat and it will wrap the rails enough, will just have a small seam after but no big deal.

Next is RELEASE FILM. Two reasons to use
1. To protect vac bag from resin
2. To help pull cork over rails in between the tape already placed during PEEL PLY application.

Dennis got a hold of me regarding my college loan deliquency? thanks
Badass Charlie!
You make it look easy. Hope you got some of that N. Swell this week.
Hi Jason. Still recovering from two days on the outer reef and 2 days inside for 4 days straight of surfing. Probably next wed and thursday for the ns. Hope you are scoring some good ones too.
cool! thanks for sharing your process!!!

I guess you were towing outside your house this week?
some people complain about how Sways isn't what it used to be and others post threads like this.
thanks again for a great thread BB30
Thank you. thank you very much. bravo.
