That thing looks pretty cool, but exactly what applications would you use it
for? It looks to be good only for face gluing a lot of narrow boards. Do
you know if he mass produces butcher block tops or something? Still, his
mechanical skills and creativity are pretty inspiring.

Pray tell, where did you come up with 5 tons, and 48" x 96"
from the OPs link?
What I see is a stack of long thin boards being edge glued to
make a bench or counter top.
2" x 96" at 10,000 lb. is 33.78 psi which is over twice what
a vacuum system can produce.
Assuming that Tom's press is 6" x 96", at 90,000 lbs,
and maximum piece thickness he can apply
over 156 psi to the piece. (over 10 BAR)
Stick that in your vacuum press and smoke it!
Vacuum presses are nice for gluing veneer but don't
work well for edge gluing.

5 tons over 48 by 96 inches is equal to
10,000 pounds over 4608 square inches
is equal to about 2.2 pounds per square inch.
That's about 4.5 inches of mercury if you used a vacuum bag
instead of a mechanical press...and the pressure would
be MUCH more even.

Why kiln dry it when you can squeeze it? <G>
That is one beefy looking tool. Keep them fingers clear!

Only thing missing is some kind of cross-clamping mechanism to
maintain alignment.
Wow ! With 90,000lbs of pressure he could squeeze out the juice from any
fruit tree woods.....
