Seems about right; 1000psi assuming a 4x8 foot sheet, roughly.
Bamboo is a -somewhat- soft pseudo-wood and can deform enough under that pressure to compress into the sheets they're describing.
(for reference, I've operated a 10kton press at a previous job, which was roughly 30 feet high + underground hydraulic lines. I don't know how many presses of this scale are even left in the US)
- crackercrews 5y agoDoes the size of a press increase linearly with the amount of pressure it can generate?
- anon_cow1111 5y agoI think; There could be other factors, but this is the main one I'd guess that, on average, the bulk weight of the press loosely determines its maximum pressure... Just because it needs a certain amount of steel to confine and direct that pressure without damaging itself. Over time, the engineering gets tighter and with less excess. You know that phrase, "anyone can make a bridge that stands up, but you need and engineer to make a bridge that just barely stands up" It probably becomes an economic issue, especially given the bigger your press is, the less people are going to need it for something.

- Cerium 5y agoPerfect, I was going to link this as well as a response to the other comment "especially given the bigger your press is, the less people are going to need it for something." Ensuring that large presses exist is important to national security but not important to most business.
- anon_cow1111 5y agoNice link indeed... I might have come across it before, though must have been a long time ago. But it does highlight the economic issues here, a govt. program was needed to create machinery that might never have existed in a pure free-market environment. I now wonder if the big "One-Press"(its nickname) I worked with was a product of that program...
