My explaination to this is that there will not be enough force on the oring to deforme because it will find its exact position (and even if the block is tightened the mostly possible, most of the force of the top will be exerted on the base itself). at least, the block which i did with hara, we followed the rules which i posted and there remained a space between the top and the base of the block, but no leak

The force on the o-ring comes from it's deformation....and yes, there is definitely enough force to deform it, it is obvious since there is a "mark" on the plexi more than 1mm wide proving that the o-ring is firmly compressed.
