Nice with a thread about Shinnster copies, I made a copy of our friends Shinnster about two years ago.
It was mainly for fun and I didn't bother much about top notch materials or so. But I have to say this board performs beautifully and has saved many light wind sessions
Used two layers of lauan plywood (3,6 mm each), glued them with PU glue in a jig to get the nose rocker (still holding up after two years).
I put a thin layer of PU polish on, to stop the wood from soaking too much expoxy resin (no idea if this really made a difference..). Then I glassed the top and bottom once and felt the flex to be too soft. So I put one extra layer of fiber on the top, turned out fine. By now the board was about 3,4 kg (original 3 kg).
For some strange reason I glassed before I painted
so I ended up glassing a little extra in the end, so it is noticeably heavier than the original
I would say it is like faklord describes, very smooth but a tad bit heavy. The original is in the household as well, so ride them both and can compare side by side.
It was a fun build and the name was to crack up my friend
If I build a new board I would also try and get a hold of paulownia ply and make a lighter board next time.
BTW, since it's so flat I sometimes have a hard time localizing it in mushy small waves if dropped. I added a piece of sleeping mat (that can be attached/deattached with velcro) in the rear end. Makes it a lot easier to spot! Not very stylish though..
