I've never used them, but I'm sure they would work if you tried them. If you are doing it for just your friends and yourself you could go the bottle jack route. The boards might delam quicker since you can't keep constant pressure. But its definetly a lot cheaper. The 50 ram that cortex is talking of can easily run you up close to 800-1000 for the nice ones, new.

Making your press all depends on why you are making them and what kind of budget you have to work with......probably most importantly is how creative you are with being able to work with what you have available to you.

pneumatics, pneuMATICS, PNEUMATICS!

clean, constant, affordable, even presure EVERYWHERE, SIMPLE. Used by some of the premeir builders in the world.

my 2 pennies.

i will post a pic of one of our pneumatic double presses soon once i put it online somewhere. (i dont know but you cant post them on the threads? ive only see skinny do it. i think he has super powers or something. like making glue dry by waving his hand over it.)

Ive slowly built a nice company over the last three years from the info here and grafsnowboards.com so i feel its my time to start to give back.

Haha!
Pnuematics are what I have always used. Consistantly good boards. Most shops require hydraulics. I am not most shops.

I've never done a lot of research on the pneumatics option. Why is there a better consistancy of pressure with air vs. hydraulic?

I didn't know you could get that much pressure built up with air either.

The difference is that with hydraulics, you need a regulation of pressure through valves and a pump. You can generate more pressure than is needed, and crack veneer. You can also have a pressure loss and lose a stack of decks.
Yes you can build enough pressure with pneumatics....in fact more than you need. pressure is never lost, and it is applied evenly with no pinched spots. With hydraulics you have to swivel or displace the pressure or you can pinch the molds in the wrong spot.

Pneumatics seem like a great direction. Anyone have an good links to suppliers that they recommend? Thanks

plus pneu is way easier to plum(connect and wire) and maintain. it an air compressor for crying out loud. everyones already got one.

As far as enough pressure? Ive built 30+ air ride suspensions that hop a 3,000 lbs car off the ground with one 12 volt battery one compressor that you can fit in a shoe box.

Nuff said.
