Hi Tom-san,TomW wrote:Kaito-san,
Round the sharp rails at tail before glassing. Fill with resin using tape barriers after / during sanding stages. Otherwise glass will not go around. R2 min.
Lamination schedule :
From deck thru to bottom :
6 oz deck patch
Laminate bottom first, tape off deck for lapp. put down 4 oz first, let cure. This make channel lamination and over boxes easier. Tenting of lam over channels is problem, therefore only 1 layer first. Use fingers to get it down. Don't stretch lam over bottom.
Then do 6 +4 on bottom. Sand to key surface between 4 and 7+4.
Then do deck in one lamination go. Lapp it over rail and grind off to tape.
Lamination and sanding those channels is challenging.
トムさん、いつもアドバイスありがとうございます！ m(. .)m (45degree bow : )TomW wrote:Doing 4+4 in one go is possible, but being first time with those channels, it's better to do one layer at a time. It adds weight. But not many grams. Seal your blank first if using epoxy. Again this adds weight but you risk dry lam if your blank sucks a lot of resin.
After first lam cures you have to sand it with 80-100 g lightly, blow off, wipe down with denatured alcohol ( dna), blow off, wipe with dna, blow off. Do not touch with hands after this last step.
Then do 2ND lam.
Deck I'd do 6 deck patch, +4+4. All in one lamination step. ( no channels)
Even with sealing blank and doing 2 step lam on bottom board will be way lighter than a Firewire board.
why not using a vac? The channels are not a problem. Sanding is not a problem either, using a peel ply will give rough surface.
If sanding is really needed, wet one is a go.
