plywood boards how good are they?

Postby paul s » Wed Jul 20, 2005 7:19 pm

Just how good are ply boards versus production? I have all the stuff to make them easily but will it slow up improving my kiteboarding skills versus riding a production board (i have an SS manta TT). I kite on the Columbia River and I seem to read posts of people much better than me losing boards every days (sometimes several a day!!). I can find tons of cheap footstraps etc so it would be great to be on $25 boards which i can afford to lose but I'm worried i'll slow my skills development versus being on a 'proper' board. If ply boards are the bizz why do guys keeping dropping $500 for boards they keep losing??

two absolutes.
plywood will be cheaper and heavier than production boards.

regarding
shape, stiffness, strength, functionality;

thats up to you, anything is possible.


regarding your riding progress;
boards are so easy to make, you can weed out the duds
alot faster than you'd be willing if paying $500 a pop.
...and you can copy any design you choose.

when you prototype one you like, there is nothing to keep you from
spending a few more bucks to make one as light as any production board.
cedar, pawlonia, balsa/glass sandwich, foam/glass; lots of choices.

have fun,
-bill

Plyboards - I've made about 5, lost or broken all but one of them. All have been good, but different to ride.

My latest is 125 * 38 or so, cheap 12 mm ply (not marine ply, just a piece that was lying around the wood shop. Cost me one euro.) with a layer of glass and polyester resin on top.

I've landed very hard on it and it just won't break! Weight is a little on the heavy side, but not a problem.

Uses old windsurf footstraps.

Not much rocker which means it goes fast, and goes upwind at a good angle - it's faster and better at going upwind than the production boards others are riding, but the nose can get buried in chop.

I have very small fins, and I've ridden it finless, works fine but i notice I tend to hold the kite at a lower angle than most - i think this is because all the edging is done with the board. Bigger fins might fix this.

Best part about plyboards is you can experiment with different shapes, sizes, rocker etc.

My latest board I made very wide, and kept cutting it down until I had a shape that I was happy with.

I've made boards with no rocker, others with flip-tips, concave etc.

I don't think it's slowed my progress - I'm learning at about the same rate as the other guys here.

I think these are pretty damn good, although it looks like the latest production board designs are starting to catch up:

Only broke one ever, in an overpowered kiteloop gone horribly wrong. That board was 150x46 so in a bad landing there is lots more leverage than on a smaller board.

i did one board for my light wind sessions, plywood for lightwind really work! I will never buy a board for lightwind, plywood is awesome for this. I have two boards, one production for higher winds, one plywood - for lightwinds. Production board to have fun in high winds, plywood board to improve riding in lightwind etc.

Have made 5 plywoods so far. Cheap and go upwind better than the production boards at my beach. Very cruisy in chop due to the flex and very easy on the knees and ankles.

125X39 130X39 140X39 150X39 and 155x39.

The favourite is 140x39 which suits just about all conditions.

They are made from three layers of ply glued with polyester resin.

Tips have about 1.5 inch of rocker.

Hollow in the middle section to save weight. See Pics

Cool board Fitzy. Did you just glass over the silk? What's the weight on the board total?

Just brushed on a layer of Polyester, layed on the silk and then another layer of Poly.

Board weighs 2,2 kg with pads, fins, straps and fins.

Here is a pic of the rocker.

How do you do the rocker, concave? You mentioned 2ml plywood, do you mean 2mm? Where I can get the stainless steel inserts for the pads and handle?
