Glassing question...

[zackoopman]

I find a good way to learn glassing is to have two mixes. One super slow mix so you can get everything wet out without stressing and then before tucking the laps pour another hotter mix over the top and squegee out to the rails and down the lap

Sounds like a big waste of resin, to me. If you do your mix for the ambient temp in the workspace, the batch should kick in a time frame that works. Since rails are done last, by the time you get to them things should be closer to the gel state and the glass should stay put. If you did a slow batch and the resin takes a bit longer, so be it. Why be impatient? Better to get things right and save resin. The stuff ain’t cheap, and you’re just making more unnecessary work.

Would six oz work bcuz I might have sum left?

Sure. But it will take more work to get what you need. Cut a square patch of cloth that will be about 2 or 3 inches bigger than the fin base. Then, you have to pull the individual strands of glass out, one by one. Stack them together and you have DIY rope.

I usually just get some heavier cloth in a small amount from a boat yard shop or auto supply store, like those small packages of cloth they sell which are usually 8 or 10 oz.

Zack - I’ll try that ! Thanks for the tips. I also need to prob tape + mask w painters paper as this resin gets everywhere ! How soon can I cut the laps at the tape lines? Is 2" inbooard ok? I dunno the rules? And if I have lumps how soon can I sand it. What grit is best? This info would help as I was scrambling w out answers last time around… I really should get more information, practice etc…watch vids to. Maybe even get a job glassing??? Thanks and HAPPY SHAPING !

No set time on that. You have to wait until the resin gels just hard enough. It’s one of those things that comes with practice.

Cut too soon, and the glass will pull and make a mess. Wait too long, and the resin will be hard and more resistant to cutting. You can do a test cut on the extra glass that will be cut away.

It should be good and stiff, but not rock hard. In other words, don’t wait until the next day to cut it. Also, make sure you use a good sharp razor blade. Brand new, like.

Cut laps—Cut the lap  when you feel it’s safe to flip the board.  Flip the board with wax paper on your hands.  You will know when its ready.  There is no set time.

you must be a pro THANK YOU ! I need to jot this great Info down from you + other’s so I don’t have to ‘hope’ it’ll come out right. That said, I think it’s going to take time… but I think prob with proper knowledge, good prep, and attentive quik but sure work -I’m feeling confident I can do it better this time. Thanks again Sir !

yup ! I think I’ll try ten times harder and prep waaay more! This shapin and glassing ain’t easy. But it does get easier each time.but it’s not easy.I’ll do my best on it.thanks -Jim

Wax paper HUH? I can do that. I’ll remember to pick sum up.ty

The “Animal” my pp/planer is on the ready. I just figured out how to fiddle w settings, so I can shape safely while learning zee ropes!? Then off to resin swirls !!!

Sammy - I read it here on sways, and poster claims if resin dries faster it wont seep in the foam adding weight.

 

Nonsense! If the “resin doesn’t seep into the foam”, then where the hell does it go to reduce weight? When you do a lamination the idea is to use as little resin as possible to wet out the glass and have it wrap and stick to the rail curves. A really slow kick can be troublesome if you don’t tend it til it gels, as the glass might release off the rails and make a mess. But, a fast kick makes no difference in weight and gives less working time. Plus, polyester resin mixed “hot” is weaker. So, given that you want the holy grail of boards (light yet strong, and pretty) you should aim for optimum cure time in your mixes.

Anyway, like I already said, the person who wrote it doesn’t know much about glassing.

That “Is” the highest plus I’ve given so far this yr ! Thanks MUCH. SammyA - I jotted everything you said, and that of others that where within perimeters of a tough/light glass job. It’s VERY possible I owned a board that only had a few minor pressure dings after two yrs of brutal use by myself. Getting the glass job would definitely make my year:l

Gentlemen, gentlemen, GENTLEMEN ! I just found a stack of 1x2s do they use these for glassing? If so, I can scavenge six of them !

I just jotted this down - thanks! I just scavenged sum wood my house mate threw out n the back . I just asked about it, and he said I could take it. Fyi its about seven nice one by two’s ! I thought I saw a glasser using setup like these, but with a T like top??I just grabbed all of it man!!

Sure. But it will take more work to get what you need. Cut a square patch of cloth that will be about 2 or 3 inches bigger than the fin base. Then, you have to pull the individual strands of glass out, one by one. Stack them together and you have DIY rope.

In 75° temps you can run 7cc of catalyst for a quart of resin and have about 30+ mins to work with. As sammy said, the hotter or colder it is will change the working life of the resin. -

If you can get your hands on some UV cure that is always a good option for first time lam jobs.

If you want color, I would stick with a single color or a two-color swirl - if you choose to go with a swirl, remember to kick your resin before you mix them together.

Use good tape for your cutlaps.

Stay clean and organized - walk through the process in your head a few times before you have a go.

Lam both layers at the same time - 1 quart will lam one side of a board under 7ft - With skill you can do it with less but thats a good starting number.

Any sloppy work will be magnified as you progress through the process

 

I just jotted this down -thank you ! The weather here in Monterey bay’s was warm today so this info will help. Thanks.

Sam - those links might need updatin - they’re dead. But thanks anyways. I think I found a vid that told me what I was concerned with.

Time to shape !
