I took a look on fiberglass supply’s website and all they had was 3.7 and 5.6 oz cloth in E or S varieties (I’m assuming this is what people mean when they say 4 or 6oz.) I’ve heard references to people using 10 oz. cloth, but where can you get it? I’m going for durability, but that might make me broke!! Looks like E is 1/2 price or so of S2. I’m trying to save money as this is my first board and it might suck, so I’m thinking maybe 3/6oz deck and 2/6oz bottom.
As I’ve never glassed before, The thought of all of these layers in a row kind of scares me. I’ve found some info on this website, but can anyone break down the process of the multiple layers from blank to hotcoat for me?
Sorry, I know this is kind of a redundant type of question, but I just haven’t quite been satisfied with the info I’ve found! Just joined and I’m stoked with how helpful and patient everyone is with us newbies!
Not sure what density EPS you’re using. If it is 1.5 lb/cu. ft. then the 6oz may be a bit much. As Greg Loehr will tell you, it is better to do multiple layers of light cloth rather than one layer of heavy cloth such as 10oz.
We made an EPS board from one of Greg’s blanks (EDRO/parabolic stringer) and we used 2x4e’s on the bottom and 3x4e’s on the deck. The thing is insane; super light and strong. Can’t remember the foam density… …1 lb I think.
Also, you could combo the glass and this will give a little bit more panel stiffness (dent resistence at the local level; heel dents, pressure dings). A combo of 6e with 4e over it is great since the 4e takes up less hotcoat resin.
Doing multiple layers with Resin Research is no problem since it wets out so nicely; just be sure to have sealed your blank! Basically, you have a sequence like this:
Seal blank
Lam bottom
Prep lap
Lam deck
Hotcoat deck + lap that goes onto the bottom.
Prep lap
Hotcoat bottom
Install hardware
Sand
We’ve built a board like this in about 4 hours as we have an oven, but this can be done over a number of days for any enthusiast. Don’t hesitate, just follow the guidlines. HTH.
I do both. On that particular board it was spackle. Pick a specific brand as some are heavier or may change color; Red Devil “MicroLight” spackle. If epoxy is used we put Q-cel as the filler and we use a lot considering the amount of epoxy; finished consistency should be like cake frosting or thicker!!! HTH.
why? if using epoxy there is no need to seal first. Sealing might reduce epoxy seepage into the eps thus cutting down on wieght but then your getting sealer seepage instead.
Unless eps bonds better to sealer (spakle) and epoxy bonds better to sealer than epoxy straight to eps (which I would be supprised if it did) then by sealing your increasing the odds of delam.
