Well Todd... it's time for me to feast on some humbe pie.

After coming to the defence of poly tops recently, both here and on a couple of other boards, my discovery is quite embarrasing. Last night I did a routine check of my block only to discover a small stress crack forming between one of the barbs and the screws in the poly top of my TC-4. Now, it doesn't leak, but it is definitely new... and I haven't touched the block since it was installed. I'm guessing that the cracks are stress cracks, and I think that my tubing may be to blame... it's pretty elastic stuff (I've ruled out thermal stress since I run SETI@Home all the time, so there's really very little thermal cycling). In any case, I am quite bummed... though I am very glad to have caught it early. Maybe I'll see how the new Swifty block does on my high flow system.
