planning on building a 16 ft board.
I decided to set up to do a wetout table and laminate bottom and deck in 2 separate vacuum bag sessions. After careful consideration, I’m worried I will not have time to do the wet out on 16ft of 200g carbon and 6 oz glass, get it rolled up on tube, rolled out on blank, trimmed, lapped, taped, release film on, bag on, seal and set vacuum in 45 min. I’m working alone.
so i started considering doing a resin infusion. researched and read the old posts on resin infusion. searched around the web and I think I’ve found most everything. not much recent material.
my thinking is to dry layup bottom, wrapping cf and glass onto rails then taped off deck. use spray glue to tack it down. wrap bottom and rails in feeder film, then peelply. Run resin feed lines around deck just inside fiber on deck, (perhaps 3 vacuum points on bottom). put the whole thing in a vbag with 3 vacuum points on bottom along center. test vacuum, then infuse.
idea is to infuse only rails and bottom. cure and repeat for deck.
reason to do one side at a time is to avoid fiber wrinkles and may need to put rocker template on one side inside bag, while vbagging to avoid distortion.
planning on using 1 lb eps.
any experienced advice welcome.
We have a good infusion resin you can use which is UV stable, low viscosity built for the exact project your planning.

Fins Unlimited spent a small fortune on an infusion table for fin sheets, it still has NOT produced a single usable sheet yet
Why are you making it so difficult? Just glass it up, do one side the stringer with RR, then do the other side. You will need the additional time to let the epoxy set up a bit so it won't slab off the rails. I did my 16fter in 6 bottom, 2x6 top. It's light and fairly strong. Strong enough to bump into boiler rocks in the kelp? But it does get ding from now and then. The strength comes from the design in the rails...nice square rails.
I used 1.2 lb foam with a stringer.
One option, and really simple to do.
Hi Resin Head,
You just did a wet layup? no v-bag ? Ive been v-bagging kiteboards, and am kinda stuck on it. ;)
Ive found a source of slow epoxy in Germany at R-G composites- bought from them before. So i can still do a wetout table and v-bag if i want to make my life difficult.

Tom I just did a wet lay up. Make it tight and flat. I'm not sure if i see the benefits of a bagged SUP?
I do bagging too, but I only bag if I need to apply some difficult material, like wood, impact glass, d-cell etc. Then I'm doing it because I don't want any air voids under the material and the foam.
Go get em.
Sea Ray boats went on a spree of resin infusion to lay up hulls, scrapped it right away, it seems resin does not always go where you expect it should.
In the case of Fins Unlim., the import orfice was in the center of the machined aluminum frame and the exit was at the far end center. Resin refused to go into the corners and the vacuum actually pulled the cloth to the far end also. The RFT fins, made one at a time, being so small came out beautifully, not a sign of a single bubble. This is a 12 footer, hand lay up with RR, super clean lam, plenty of time to dry it out
