What I normally do is make a plaster cast of the board then measure the water needed to fill it.
^^^^
That got me thinking.......
And yes I'm sober Sparky , olskool.
why not cast a mm perfect EPS blank. .? It would even have a nice smooth skin .
Starboard I'll take my royalties in a custom Cobra factory tour , build your own board , voucher thanks.
Imax1, i think thats how the SPEED series Raceboards were done. A heated mould had styrene beads fed into it. The blank was thus 'shaped'. Then top n bottom moulds were layed up n put together around the blank n heated to cure.

Bugger in 20 years too late.
But why not do it nowadays ?
Because it produces significantly heavier boards - vs sandwich construction.
And nowadays lots of boardshave their cores machined (not hand-shaped), then placed into a mould.
If you look at the various posts on Seabreeze, the core is almost an insignificant amount of effort... relative to:
a) sourcing the correct tools ...like say a vacuum pump
b) sourcing materials... peel-ply
c) inserting the various plugs and boxes
d) finishing
e) painting.
F) cleaning up your workshop at each step, so your partner doesn't leave you.
It is done nowadays
Severne kinda is with a blank that is slightly oversize, then into two very heavy moulds- compression moulding. Best of both worlds.
Can't be done without significant investment in tooling, even little things like placement of inserts can be way dfferent to the easy router and bung them in.
And a CNC cut blank still needs hand finishing due to the little steps all over it.
After 30yrs of sandwich tech in WS boards I think we have got it right. No need to screw with it.
(Well, apart from the continuing reduction in materials to try and give us what they think we want....eggshells...... when IMHO the durability peaked about 10-12yrs ago)
I actually meant using sandwich technique . Just the blank being cast instead of machined. For the big company's making many of the same board.
