I was thinking about cutting out a hole in the deck of the board and putting a plug of honeycomb in the hole. Then attach the honeycomb to the foam with epoxy. Has any one tried it before?
Most peeps I know who cut a square out of the middle front of the board just add to pieces of plexiglass, and see the bottom!
Usually NOT the greatest idea to cut away the stringer completely, eh?
You could cut a hole on ether side of the stringer the put the honeycomb in the board.
Hmmm. You don’t say why you’d do this. Will the honeycomb be that much lighter, after glassing, than the foam it replaces? Probably not, or not enough to make a difference?
Overall, an inventive approach, potentially an interesting project, but thus far, no demonstrable value. Keep thinking.
Where would such honeycomb be available? Where is it being used? How is it being used? Why? In preference to what alternative? more…?!
Being french, I apologize for my lack of technical words.
Mechanical abilities of foam and honeycomb are quite different.
I’d rather worry about tensions betwin materials than think about how light you can go.
Light boards are not necessarily interesting. They need far to glassy wave to surf nicely.
I made bellyboard back around 1980? I used a router to remove part of the deck. I used honeycomb to replace the foam and the board was laminated with Kevlar. It was very light (about 3 lbs) and very strong due to the Kevlar. Read Surfer Mag. Design Forum 1982-83?
