Great video, thanks for the effort. But being a natural-born commentator, I gotta suggest a few things. Also, some notes about what NOT to do are useful, since there’s more than one way to skin a cat…
One round of 3/4 inch wide Scotch 233 tape is about all I used for most cut laps. Only on the most curvy noses or tails do I use some 1/2 inch tape. Tape’s expensive and expendable.
Two, although the Scotch 233 has excellent “stick” and is really impermeable to resin, since I’ve been using UV cure, the resin sets so quickly that I don’t need the impermeability the 233 offers. I have gotten away with plain old cheapo masking tape on most colored lams. If the blank is sanded (100 grit enough), blank cleaned with compressed air and the tape firmly pressed down, the “plain old” tape works just as well. I use the cheap tape because (one) it works and (2) Scotch 233 is $4-something a roll versus “plain old” for less than half. Hint to anyone in Honolulu: Kilgo’s price for 233 is excellent. The price at that place on Colburn Street sucks.
After laying one round of tape at the line, lift the inner edge of the tape, slip the paper under it, and set the tape down firmly with your finger. Much less tape used. Where individual pieces of paper join, a one-inch strip of cheapo tape perpendicular to the rail is good insurance. Usually use a couple short strips at the nose and/or tail also rather than cut the paper to fit the curves.
My paper doesn’t to all the way to the other rail. Doesn’t need to, but it is nice to have the whole non-laminated surface covered in case you need to adjust the position of the blank on the rack, midway through the job. Much more likely to happen with short light shapes, of course, than when laminating tanks.
I use blueprint paper, folded once. Though it’s relatively porous compared to butcher’s paper, I’ve got tons of it (engineer, right?). Folded once, the two layers at the tape are enough, especially when using fast-setting UV cure lam resin.
Another backyarder gave me a good tip: instead of using paper to mask, he used waxed paper. Mom always has this around, thanks Mom.
DON’T USE NEWSPRINT. The ink comes off on the blank, and it’s absorptive and porous as hell.
