Hi who is making their own boards round Sydney, and how do they go?

and that they feel itchy.

I've made two proper rideable boards to date (and two others that really should be forgotten). The new ones are built up on a polyethylene rocker table and have a foam core with glass & carbon skins. If you were considering building a board I would strongly recommend making it on a rocker table as it saves a huge amount of shaping and jig making. I vacuum bagged these boards but I haven't really perfected the technique just yet - I still have excess resin in the lay-up. You can build yourself a vacuum pump with an old fridge compressor and a few other bits & pieces. I also made my own foam sandwhich fins and foam covered aluminium grab handle. A pair of home-build pads with old windsurfing straps round out the true backyard package.
Both my boards (139 x 39 & 137 x 41) have come out a little bit light and a little bit flexy but are perfectly acceptable to ride. I don't have any other boards to compare them to but I don't have any problems riding with them up to about 20kts. My preference is to switch to my flx 22 at about 16kts though - smaller is funner.

They're both oriented to lighter winds and intermediate riders. It takes a few goes to get it right and I'm finding that each new board comes out better than the last. The next one will be shorter, narrower and with a little more concave than the last ones. Each board probably costs about $100 in terms of raw materials but that doesn't include the cost of nice new style pads, straps and fins.
There is a global shortage of carbon cloth on at the moment and I've foolishly used up most of my old supply on the first two boards so I'll be making the next one out of mostly glass with just a few patches of uni carbon on the top deck. If you want to know more I'd check out the boardbuliding group on yahoo. There is a massive amount of information on there including all of the tips and advice I got before building my first boards.
Cheers,
Munter
