Thats actually pretty cool I think. So cobra don't just make sailboards do they, they do stand ups and surfboards for the surf tech range don't they?

so a good fifteen years ago (keen but no real idea) we bought a second hand sailboard from the trader that was a cobra board.

god knows where it is now, hopefully landfill somewhere as it was a pig of a board. worst of all was its nasty metal mast track with sharp edges bolted on top of the board, not built into it. perfect for lacerating your foot.

i've not seen a cobra before or since. surely not the same 'cobra'...

Cobra builds most production boards you buy today

F#ck! And i thought they made snakes there!

If that's classed as a 'big' factory - I'm not very impressed. Walk into most joinery shops these days with 10 or more employees & you'll see more advanced cnc machines. I would've thought that it would be more automated, and as mentioned above, less wasteful.

seems an awful waste of material.
surely the blanks could be made closer to a shape and then just refined.

EPS comes in big cubes. And at an educated guess, these are prototype boards.. This is not the Cobra factory, which probably wouldn't use this method..

I have a block of EPS foam in my backyard 2200x1220x660mm and I cut board profiles out with a hotwire, and the rest goes in the bin (mostly via a vacuum cleaner).. That equals 1600L of foam, and I could potentially get up to ten 80L* boards out of that...

I bought that block from a foam supplier in Campbletown for $380, these guys probs pay 1/5 of that..

*more wastage if I cut two different profiles that don't match, and I don't need ten 80 boards.. So I wont get ten blanks..

2200x1220x660mm

that's a short board barnacle, or do you use your knowledge of pythagorean maths to extract extra length?

your right but I guess this would then need more moulds. from what I hear are v expensive so its probably cheaper just to start with bigger blocks

Barn have you made any more boards this year??
