Just as a side issue, why forgo an over-the-die inlet unless being able to put pressure directly above it is important to your mounting system?
(Like the Innovatek Rev 3, for instance - see how clamping pressure is applied through a single point directly above the die?)
All very academic at this point, anyway, as Belenar seems to have caught you dead to rights. Aren't you just a bit embarrassed? Hint: Apologize and if you want anything other than negative comments here send a block off to someone willing and able (both equipment and time) to test it. You're not getting responses from pHaestus as he's been very busy (so he has the equipment but not the time).
Fantaz has offered to actually
buy a block - dunno if Fantaz has the equipment, but it sounds as though the time and willingness are there.
Also - I'm guessing you've gotten these blocks from mainland China (?) In the early 80's I had some dealings with a man from the PRC who had factory "connections". At the time they were making knock-off copies of athletic shoes (and BTW also trying to figure out what else they could produce with the excess capacity they had). They were very good copies, including how they performed when on your feet (he gave me a couple of pairs to try). Check out what percentage of athletic shoes come from the PRC now.
I've seen the same thing happen with industrial fasteners.
Maybe watercooling has gotten enough mainstream that PRC factories are at least thinking of producing wbs with excess capacity?
All supposition, of course. Don't quote any of this as fact (except the shoes and fasteners history
)
