You can cut holes in the spine, just as long as you don't make them really big or too close together. I would leave the thin ends alone and keep the holes concentrated in the thick middle section of the spine. The spine is quite over-built at 1/2" thick, some people use the thinner plywood and still drill holes in it. As far as weight saving, I don't know weather it's worth it, but it wont hurt to shed a little weight! Chad
Today we went on and ripped 1" boards into three 1/4" boards for the top and bottom decking, but really only got two salvageable boards from each rip. then we plained them, thats my dad whos been helping alot in this project, his shorts are vintage not from a shop but bought new in the 70's classic blue corduroy.
So once it was clamped glued, sanded and ready for the spine and ribs to be put on, we put the spine and ribs on.....as you can see in the picture they deck is wayyyyyyyy small. should have figured this out before, I think I even thought about it when we were plaineing and gluing, but in the materials list when it says boards for decking equaling 24 inches in width, I imagine thats for a different surfboard. So after some more planing and gluing we are back
a crack had appeared in the middle board, it runs about 40' straight up the middle. We gorilla glued it and sanded it down so it looks ok on the bottom, the top looks ugly still but my new concern is that it will not be strong enough. I need some help and opinions. we have a few options.
1) cut the board, square the side boards and re glue removing the crack completely. 2) leave it alone and assume it will hold, given the strength through fiberglassing and foam filling, the decking board is oversized and the major injury of the crack will be removed by about 12', leaving just the minor hairline crack
the other question is if we leave it and assume it will be ok, should we put the cracked end at the nose or the tail?

The crack should not be a problem at all, remember, most boards are made of foam which have very little structural integrity until they are glassed. Wood boards are almost as strong as a lightly glassed board even before they are glassed.
I also had a crack in my 11' sup. the bottom crack was maybe 10" long. I also had some gaps on my rails due to bad clamping on my part. When I got to the glassing I took the epoxy and mix a bunch of that sawdust into it and filled the gaps. It worked pretty good.
