Thanks for the good news... I'd hate to have to start over at this point!
I might do a quick run around the top to take off an ounce or so because I can,
but won't make a big deal about it.
I need to make a seat for the clamping spring anyway. I've gotten some 50lb 'die springs' from McMasters, my plan is to make a pair of 3 tab plates for each CPU that will stick up above the block about 1.5", with a piece of 1/2" stainless bar connecting them. Over the center of the CPU die I'll put a 1/4" threaded hole. A bolt or peice of threaded rod goes through the hole almost to the top of the block, but not quite. A nut and washer big enough to go over the end of the spring goes on the rod, followed by the spring. The spring pushes the WB onto the CPU when the nut is tightened down, and pressure can be determined by the amount of spring compression. (McMasters reccomended 15-20% compression, which works out to about 25 pounds)
Sound reasonable?
