I'll have to look at mine as I wasn't aware of the difference. As for the long time setting stuff, its quite tempurature sensitive, so I often will get it together, and put it in the oven, set for about 125F or 130F. All done and ready to go to work if left in the heat for an hour, then cooled back to normal temps. That doesn't stop it from running as its as thin as water with a very strong wetting agent in it at 125F. > The other often has an annoyingly too long working time, running > off or settling into low areas while you're wishing it would hurry and > gel.

I blew it clean, hole and all with a contact cleaner, waited a few for that to dry, and used a torque wrench to re-assemble it at least 2x tighter than I had pulled it with the long leg of a 6mm wrench by hand previously. So I never had it tight in the first place. I also turned the flat washers around as they were only flat on one side, putting the slightly rounded faces against the screw cap where the curve quite markedly reduced the cap to washer friction and putting the flat face against the carved recess in the sled, putting more of the 20 ft/lbs torque that Andy noted into the screw threads. I think I've got it tight this time. And I did not detect that I was 'stretching" the bolts. Thanks Gregg.
