I'm back at it.
I eventually managed to find 2 pieces of Divinycell foam, 1 inch thick, so I'm planning to use the time this winter to build a couple more pocket boards! I should receive them in the next couple weeks.
I already built 2 pockets, using cheap polystiren foam, wood stringers and glass/carbon hand lay-up. Nice, strong, but not particularly light...
This time I want to try vaccum bagging (never used vacuum technics before...) to get the weigth down and hopefully nicer finish.
Would you mind sharing any good step by step tutorial - viceo or other... - for vacuum baging an HF pocket board?
- No significant "shaping" = cut the outline, round the rail and sand the nose a bit... then use the lay-up to give the rocker. Similar to what I did in the past but not sure if the divinicell will bend enough without breaking...
- No stringer since the divinycell foam is a lot stronger than what I used in the past... but UD carbon top and bottom
- Simple "through deck 4 screws" foil plate attachment.
- Lay-up in 2 steps:
1- deck first (while giving the rocker at the same time using my home made rocker table...)
2- then the hull
I'm especially worried about finding the right technic to wrap the rails nicely and create overlap with the different layers of carbon when doing the top and bottom.
