You’re using 1 -komp polyurethene glue ? the type that hardens/dries from h20 ?
Yes I’m using PU glue thats expands and dry using H2O.
Here’s the board finished (I’ve posted those pics before, sorry for those who seen this stuff already):
Thanks Pierre, great pics.
I was thinking along these same lines. The only thing that has been troubling is that I can’t figure out how to clean out the excess glue from between each strip on the inside as the structure closes up. Am I correct in assuming that you are leaving the internal frame in place, in effect making it your building jig?
Pat
I didn’t clean the excess glue on the inside part (expanded PU glue is light) and I did left the internal frame in place.
Pierre, the stick under your armpit is OK, but you forgot your basque beret and the usual bottle of wine. Let’s keep clichés alive, please…
Hi again everyone.
Well, I’ve just spent the last four hours reading everything I could find on hollow wooden boards. There is a lot of great experience, pics, everything out here already. I’m getting pretty stoked, and will be buying some tools this weekend and testing out my cuts, joints, on scrap before I begin the project. At this point, due to the fact that I didn’t end up getting a shortboard I thought was coming my way, I’ve decided to emulate some others here and go for a fish. I’ve got a friend with a sweet 6’0 fish that I’m going to use as a template.
One thing that has been talked about a bit but I wanted to bring up again is building a board without glass. A while ago Paul Jensen said that "Ply inside needs no glass… Wood strips require either: A thin ply over the frame, with the strips “contact cement” glued to the ply… or Wood strips laminated together with glass or carbon fiber…I’m thinking CF on the underside of the deck, and fiberglass on the inside of the bottom… "
But on the other hand Roy Stewart has been doing this for quite a while and doesn’t use glass at all. I really like Roy’s point about not bringing glass dust into the home. I personally don’t have a workshop, and will be doing the work on nice days in my postage stamp yard after a morning surf. The project has to stay in my bedroom between work sessions. So here’s what I’m thinking…
I’m going to try to use 1/4" by 3" cedar, possible sitka spruce (a little heavier, but non-resinous so that should be better for epoxy.) I’m planning a ship lap edge, but have also considered bead and cove, for the decks. I’d like to coat the inside of the decks with epoxy/muslin cotton, and the outside with only epoxy. Here the spruce might be better, because without glass I’m going to really need the epoxy to soak into the grain well. My main concerns are strength, since I often surf overhead waves and get thrashed, and the health/patience of my roomates since I share a house and will be lugging the project inside every day.
Thanks for the input everyone. I can’t wait to get started on this one, everyone else’s boards look sick.
By the way, any wooden board people here or reading in central california? It would be good to meet up and check out each other’s work.
Pat
so if the hollow wood board was invented in 1926
whats up with these guys in aus 1919?
Maybe the date stamp inside the camera was set wrong…
My Canon came from the factory like that…
Just kidding…
