windfreak74 just posted this tidbit of info in the "Why bother with ABS rails?" thread and I thought I'd copy it here for anyone searching on urethane rails: from windfreak74 - "Guys, Never used this product but if liquid force is using liquid rails(urethane rubber for rails)maybe is worth a try. He...

daspi, here's an example of doing poured resin rails (question from your hotcoat thread, but the response is more relevant to this thread topic) poured-resin-rails.jpg Here's the full build of that board which gives you a better idea of what's going on: http://www.blacksail.fr/index.php?rub=FABRIQUE...

I was going through my bookmarks looking for something specific and thought I'd post up some of the interesting stuff I've come across. Cool site, it's in French- http://www.blacksail.fr/ Some good videos on making a dcell board: http://blog.jamestowndistributors.com/?s=kite The videos are nice beca...

Very cool! I did the same thing for my first board. A nice big board is much easier to learn on. Try it without fins and see how it feels. It may be OK. I put really small 1" keels on mine just to keep it from sliding out a bit. If you want to put fins in just mark the positions for the holes, then ...

"So, how do I do it with a thin kiteboard?" That's the problem. The glass won't wrap around the really small edge radius without causing lots of problems and headaches. Surfboards have nice rounded radius rails (mostly). All kite/wake/snow boards have really thin edges and none of them wrap the glas...

Just stumbled across this bit of urethane rail info on the LF boards: "The new addition of Liquid Rails (poured urethane rather than ABS) has increased the durability and adds to the overall smooth ride that you get with the 2010 Liquid Force Influence. " Source: http://www.realkiteboarding.com/inde...

My guess is ABS was used to streamline the production process. They want to be able to make boards in the least amount of steps possible and by putting ABS rails they can do the top/bottom layers in one hit on the press (they use huge hydraulic presses not vacuum bags for production boards). So it's...

You pretty much need to do the hot coat to fill the weave. You end up sanding most of it back off anyway. With poly you use sanding resin (resin + a little wax) and with epoxy you just use straight epoxy. It will be clear. If you don't care about light you just don't have to be as aggressive in sand...

To answer some of the questions - Yeah, the glass helps the flex quite a bit. The 1/4 plywood is more like 3/16 so 2 layers is really closer to 3/8 thick rather than 1/2. A single layer is easy, keeps the weight down, gives it decent flex and keeps it all waterproof. A hotcoat is a filler coat of re...

So I finally finished glassing my 2nd plywood board. This one is made of 2 layers of 1/4" Birch plywood glued up on a rocker table - glue-up-side.jpg I was planning on vacuum-bagging it but the fridge pump I had died, so I decided to hand glass it with UV Polyester resin. I glassed the top first wit...
