My homebrew wakeboard
 
I know it's my first post but I'm a longish time lurker...

I've noticed a few people have posted their board builds recently so though I'd add mine to the mix :)

It's still not quite finished but getting there,

Spec's:
1420 x 445 at midpoint, 300 tips
Approx 3kg (6.6lb) but the next one WILL be lighter, aiming for 2.5kg (5.5lb) or less
10mm concave at midpoint, flat tips
late 3 stage hybrid rocker
wrapped rails at the moment but next board will have PU or ABS rails
Full Carbon Fibre & foam construction using UD, Bi-axial & twill weaves
Foam is 6mm (1/4in) Corecell M80 from Gurit, propper marine foam with decent mechancial properties

This is the foam all measured & cut out with indert positions

Layed up and in the vacuum bag, the next board will have a heated cure in the oven. (The resin I use likes a higher temperature cure cycle)

Demouled and first trim but shows the amount of rocker

Edge to edge concave, should edge well but expect it to be quite unforgiving.

Rocker profile, the camera has skewed the angles a bit as it looks a little squashed

The basic board, first trim done but needs a bit of work to get a decent finish
<a href="https://www.flickr.com/photos/landychris/13100998163/" title="2014-03-12 08.48.06 by landychris, on Flickr"><img src="https://farm4.staticflickr.com/3811/13100998163_f74b5f4293_z.jpg" width="360" height="640" alt="2014-03-12 08.48.06"></a>

The concave is quite high so I'm going to have to lay up some extra over the heal/toe of the bindings to ensure it's flat.

Thats it so far :) once I've done some more work on it and taken it out for a ride, I'll post up the results

wow nice work! Looks like it'd be a fun ride. Can't wait to see the finished product

chrislandy 03-22-2014 2:03 PM

Thanks :) forgot to add it's got 4 carbon stringers in it too (the cut lines in the first picture)

fly135 03-22-2014 4:46 PM

Awesome! Looking forward to seeing videos of it on the water.

LeeG23 03-22-2014 5:13 PM

That looks like a fun project!

mikeab8 03-22-2014 8:42 PM

looks awesome can't wait to see the finished project!

nuckledragger 03-23-2014 7:42 PM

Looks good! Let us know how it rides.

that's is cool but for real how much time, money, and effort will go into this by the time its perfected? I can get year old new boards for 200 byucks now on sale and slightly used board for 150.00

do you think it will be worth all the time and effort and what are your real costs?

I think you are missing the point. I don't think cost is in issue in this project. I think it is pretty cool project. If I had the tools and knowledge I would love to make one.

It is pretty awesome to see somebody do this! This could make a good pass time hobby! I would like to try something like this if I had the time and materials. What did you use for a mold? I am assuming that you used wood for the mold and just have a smooth surface on the bottom of the finished product.

Time isn't an issue, I've done this to fill time between projects. Cost isn't the issue either as I had a lot of the materials already. If I was to add all the materials up that I've used it's under £150 (circa $250). Even though the cost isn't a factor in the project, a new high end wakeboard in the UK is at least £400 ($680) and you don't save that much by importing from the US once delivery, import tax and VAT have been added

I made the mould from plywood to get the shape then the layup surface is perspex / acrilic to get a nice smooth underside.

Work has gone a bit nuts now so won't get time to work on it for a week or 2 :(

Quick update on progress, the foot pad area has been bonded on

<a href="https://www.flickr.com/photos/landychris/13534884054" title="2014-03-29 21.36.36 by landychris, on Flickr"><img src="https://farm6.staticflickr.com/5495/13534884054_5d902dfc88.jpg" width="500" height="281" alt="2014-03-29 21.36.36"></a>

It's now been sanded and shaped ready for the reinforcement to be added over the footpad.

Pretty cool stuff

chrislandy 04-07-2014 4:02 AM

Just need to add the fins now so progress to date:

https://farm3.staticflickr.com/2819/...b2507a4041.jpg

Board is now laquered but it really shows up the flaws now so I might sand that down and paint it to hide it all with a few choice bits of carbon showing...

https://farm8.staticflickr.com/7016/...0157b08979.jpg

https://farm4.staticflickr.com/3696/...5b1e4765b7.jpg

It actually looks better in the flesh, the photos seem to have emphasized the flaws unfortunately :( As it's my first board made like this, I'm pretty happy with how it's come out as the astetic wasn't top priority, more proof of concept for the next board :) The addition of an opaque topsheet would hide any distortion in the weave too.

Finished weight 3.6kg, so a bit on the dumpy side but I also know where I can take out the weight for next time...

Well.. it worked! Not me riding btw though it's Ross Phillips, one of the British mens team
