Rocker traditional glass

When i am glassing my skimboard using traditional methods what is the best way to get rocker into it? it only needs about 1"-2.5", not that extreme?

thanks

Is the S board made of wood?

if so then you may need to somehow clamp it to form it in the shape you need and let it set untill it takes hold

you may need to wet it, clamp then wait for it to dry,

glass it after you get the rocker in it.

no sorry its a foam skimboard

thanks

Easiest way I’ve ever seen to do this for a one-off is to cut your

rocker into one edge of a piece of wood and then tack the foam

(down it’s deckside centerline) to that edge. Then laminate the

bottom, let it cure, and pop the board off the “rack”. You should

be able to glass the other side normally but check your curve and

be ready to adjust (by weighting on a FLAT surface with the nose

jacked up) as the glass job cures.

Is it best to glass the bottom or the top first?

Thanks

Bottom first. The rocker will hold better when the load on the glass

is compression. You should be able to glass the deck on a normal rack.

But as I said, watch the curve as the deck lam cures, and be ready

to help it out. If you did a bunch of them, you’d probably figure out how

to allow for the springback by adding a touch more curve in that bottom

lam. If you put a lot of glass on the bottom, it’ll probably hold your curve

pretty well, though.

Make sure your tackdown is EXACTLY down the centerline of your deckside

or you’ll get a twist. Let that bottom lam cure on the rocker curve for a

day before you pop it off.

Hi Magicmack -

There was a guy who used to post here who had some out of the box ideas. Peter Rijk had a couple of methods on adding or subtracting rocker during the glassing process. One method looks like he suspends the ends of the blank, uses fiberglass strips to pull down the rocker in the center and then glasses over the strips. You wouldn’t be able to do an overlap at this stage but you could add some rocker.

The other method he posted uses a plastic film over the lamination with strips of tape to bring down the ends. I suppose you could use strips of tape in the middle too, to add some rocker. Not sure if this method would leave imprints of the tape strips. Also… he may have meant this as a kind of poorman’s bagging method(?)

I’ve thought another way with a conventionally stringered board might be to screw tiny hooks (as used to hang coffee cups or picture frames) into the stringer and hang weights while glassing the other side. This could be used to add or subtract rocker by placing the hooks in the middle (to subtract rocker) or at the ends (to add rocker.)

As has been pointed out, there is some springback associated with these methods so put a little extra tweak in there.
