    Clemsonsurf after Sandy post some updates with your glassing? I made a few longboard design sketches thanks to this thread. It'll be a nice winter project.

    Resin Research is the stuff most hws builders use. i've glassed with polyester with success.

    Just a heads up for future wood board builds we carry wood kits from a california builder. The guys at Grain sell great kits too and a nice bunch of guys.

    Clemsonsurf, how do you like riding your wood build?

    Man I wish I could tell you differently but the board is kinda a dog... Pretty heavy and it has too much rocker in the nose for the shape. It all started with the frame. I used 3/4" poplar and not enough lightening holes. The sapelle was beautiful but I think I'll use it as an accent next time, it's pretty heavy too. The nose block has more in common with a battering ram, it's about 4" thick red cedar. Looks cool though.

    The glassing went pretty well. I used solarez and it was pretty straight forward and quick. Unfortunately I did most of my glassing at night so i had to make it kick with the mekp. So much for the UV catalyst. I want to try epoxy next time... Less fumes. I got the weave from fiberglass supply Florida and they were great. I'll use them again.

    I had to get creative with the vent plugs. Finally went with brass plumbing fittings to fit the theme of the board. HEAVY.

    With all that said, the board floats and it'll catch waves all day. And to be honest we haven't had a good day to really give it a good work out (I finished it up maybe a month ago).

    Like I said earlier, I'm going cheap and light for the next one or two before I spend money on good wood again.

    Lastly, it's on sale for $299,999.99.

    Out of curiousity, had you ridden any wooden boards before?. Ive never ridden anything but poly and EPS boards, and except for twice at Grain Surfboards demos in some fun sized waves The extra weight was definately noticable, jumping off a poly board right onto same sized Grain board.

    About the nose rocker - when you trim it out does its feel like its pushing some water under your front foot?

    Well, when i was designing the board I wanted to make a "medium-simmons" and I put in too much rocker in the nose from the beginning. Then while building the board I had to add in a little more rocker in the nose to make up for some mistakes. The extra rocker was noticeable for me when I was higher up on the wave and needed to drop down again to make the next section. I think if there was less nose rocker I could have made those sections easier, I mean I was nearly noseriding this thing and it didn't drop in.

    As far as trimming I don't feel it pushing water but I know what you're talking about, I have a fun shape that pushes water at lower speeds. The board is very wide so it planes really easily. I also incorporated a single concave so that may reduce pushing water. HWS1.jpg HWS2.jpg HWS3.jpg

    Oh yeah, this is the only HWS I've ridden. We don't get too many board demos other than SUPs in Charleston.

    Yea... by the looks of it, you're describing exactly what one might expect regarding that nose rocker. You can actually get away with some added nose rocker if you keep it up near the tip... some "flip" is ok, and it works well on those short, flat, wide shapes.

    Still a beauty, though... nice work.

    Interesting. It does seem to have a good bit of continuous nose rocker in the front 18-24 inches.
    As wide as the tail is, and looking like its pretty flat rockered back there, i would think shifting your weight to your back foot thats planted right over those fins and that big flat rear end would produce a nice burst of speed once your line is set.

    Nice job by the way.

    Just read through this whole thread again and it's inspiring me to get going on my build. I've been sitting on some paulonia and red cedar all winter and I think it's time to get started. Nice work ClemsonSurf!

    That's great! It really is a fun process and you have a lot of "I'm really doing it!" moments. Let me know if you want some pointers. I spent a lot of time thinking about ways to do something, doing it, then realizing a much more obvious and often easier option. There is a ton of info out there and videos on youtube.

    I had to keep reminding myself that I'm not making a high performance board that will magically make me win contests and I've also come to the conclusion that I'm probably not gonna be the best surfer but I may have the best looking board (unique at least).

    Making a light HWS is a real challenge. I've been using 1/8" plywood but it needs to be reinforced inside and outside. At the time of my first board, the unavailability of e-glass made me glass the board with chopped strand mat, which is a PITA to work with and you need yo sand a lot to end with a decent surface. It was heavy but indestructible. After that, I glassed 2 board with the proper fiberglass and they didn't came as light as I supposed. Think the weight is in the inner structure and on rails (solid plywood - Jensen style). Venting is always a problem, but now you can buy goretex vents which simplify things a lot. For the last 2 boards I filled them with canned insulation foam, and no vent at all. Next time I'll do the same, with no inner reinforcing, a lighter structure (with cross members every 6", maybe 4" to support the deck)and hollow rails, to see if this helps. If I can get 1 lb per foot of lenght, I'll be satisfied.

    Check out HWS #2!

    This one is significantly lighter than my last one and a much cheaper build. It has a single concave throughout and I'm going with a quad. Not much to change now but the fins are not set yet. Any opinions on where they are now? I may go a little further back and closer to the rails but not much.

    It's about 6'3"x22"x3".

    Looks pretty good. What should the final weight be?

    Is there a touch of hip in the outline? And what is the tail width? On really wide tails, I like to go in from the rail a bit more than "normal" tails. I also like no more than 1 1/4" between the leading edge of the rears, and the trailing edge of the fronts, with the rears set about 1/8" more in from the rail than the fronts. This is for single foiled fins.

    What are the fin layout numbers you're thinking about?

    Is this all plywood construction?

    Look'n good!
