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.
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 : )
Really, MUCH appreciation!
I'm tempted to post pics, but will wait till I get the top coat sorted..
I did manage to get the bottom lam on last week (one 4oz)...and learned a lot..(read - 'made a few mistakes'..) ... (o^^o)
Less than mid way into lam, the resin started to go off pretty quick, even with almost all of it poured onto the board..& a/c cranking..
In addition, only have worked with thin paulownia boards up till now, so I misjudged the amount to resin I needed to get full saturation through the rail wrap & to the cut lap..
With an emergency batch, I was able to make it through...but barely..Result; a fairly messy, dry spotty cut lap..
So, I managed to carefully sand out the dry patches & clean up the rookie cut lap over the weekend, plus get some color on the deck.
I'll be doing one more lam over just the rails today(4oz), to cover the clean-up job & add some strength. Could use the extra cut lap practice!
After that cures, will lam the deck right after. Sched, top to foam; 4+4+4deck patch+vector net under standing area.
Would prefer 6oz deck patch, but I only ordered 4oz this round of supply order.. next board, 6oz for sure!
Resin & hardener are in the frig, plus have the ice-bath ready for the next round of lams!
