Thank you very much, Cathar.
I posted this question on the OC forums but received no response. I Googled and found some Intel data sheets, but not that one.
As part of my search here I came across threads with information from BillA, who gave the 100 lbf value, and Morphling1, who gave a value of 70 lbf.
As I certainly consider both of these gentlemen to be knowledgable sources, I did not know what to do about the discrepancy. Granted, the 100 lbf is a maximum, so 70 may be a good practical value.

My remaining issue is how to achieve this pressure. Some recommend that to get this amount of force, I should dispense with springs altogether. If I use NeoMoses' method (since I'm mounting his block using his 6-32 threaded rods and his 4 lb springs), I would need to compress the springs 6.25 inches -- pretty tricky on a 3.5 inch rod.

Any suggestions? Try to find 12 lb/in. springs? Or lose the springs and hand-tighten everything down as hard as I can?

I'm at a stopping point in assembling my system until I can comfortably resolve this. I've PM'ed Neo about this and will wait for his recommendation since it's his hardware. I very much appreciate your response and would be open to any suggestions that you and the other members of this forum might have to offer.

Thanks.

Edit: BillA responded over at OC while I was writing this message, again giving the 100 lbf figure, so I feel pretty good about that. Still just need to figure out how to apply it.
