Hey Everyone
Not sure if this got posted already as I have been away for a while, but I saw it tonight and thought it was pretty cool.
Using the pressure of the ocean to press a snowboard!

Crazy idea! Does anyone else think the guy looks like Chuck Norris?

Hi Guys,

The underwater press idea was mine, I'm the diver featured in the video with Dave from Signal snowboards.
The fundamentals of underwater pressing is pretty straight forward, the diving bit and taking it to depth increases the pressure however it is completely possible to build a water press and submerge to a depth of just a few inches for instance beneath the surface which will give pressure just over full vacuum. In the shoot we used a venturi attached to a one way vac bag valve to get the air out before submersion but it is possible with no machinery if a water proof bag was constructed with a gas tight zip ( dry suit zip ) and a dry suit air release valve ( essentially a valve that lets the air out to form vacuum when submersed in the waters pressure). It's perhaps not the obvious way of doing things but it works.. If anyone has any questions about the build please ask. It was a super fun experiment. Lance.

So you're saying we can start building boards in our bathtubs?

It's great to see someone from skibuilders contribute to this awesome web series!

I think that makes the ocean the world's biggest autoclave! That's pretty awesome, great video!

(as an aside - sometimes I feel like my layups are as hectic and messy as them doing it on a boat )

Way to push the envelope!

sick, glad to see some of us repped!!!!
I like how you guys used another snowboard for the form

I might do my next layup video in a wetsuit!

Must have been some ultra low temp cure epoxy. What is the water temp like in Milford sound? Must be near 10C?

I was thinking that was part of why it fell apart. Not quite cooked yet.
