(...) It might be a couple of things: - A newer, slightly more pliable breed of ABS is being used. It is more readily available, holds it's color better, is available in more colors (rather than having to add a lake [dye] to the ABS beads), and (...) (24 years ago, 13-Jan-01, to lugnet.technic)

(...) Thanks for the information everyone. I just brought this back up since I recently acquired a rather old model (sealed/MISB 8865 Auto Chassis) and noticed that some of the pieces were extremely tough to put together, particulary the (...) (24 years ago, 15-Mar-01, to lugnet.technic)

(...) what I've noticed is the black friction pins - many models I've bought already built I've found it extremely hard to remove these, requiring me to push with an axle very hard. A couple I haven't been able to remove at all - I had to drill them (...) (24 years ago, 15-Mar-01, to lugnet.technic)

(...) I thought that the whole idea of the introduction of the black pins was to provide this friction. You use a grey pin when you need elements to rotate about them and a black one when rigidity is required. I'm now wondering if I should sort my (...) (24 years ago, 15-Mar-01, to lugnet.technic)

(...) I agree, I think that is the difference between black & grey. I don't think there's significant difference in friction between "slotted" and "un-slotted" black pins, but they do (both kinds) allow some rotation, just not as much as the grey (...) (24 years ago, 15-Mar-01, to lugnet.technic)

Ah, yes ROSCO, I've been a bit of a fool here... (...) Clearly they would have to or you would have to pull them out and replace when you need to move a beam's position! And if they were tight enough to resist any rotation you would never even be (...) (24 years ago, 15-Mar-01, to lugnet.technic)

(...) They still allow rotation, albeit with some friction. I think the point of the black pegs is that they don't have any slack for movements other than rotation, unlike the grey ones. Jürgen (24 years ago, 15-Mar-01, to lugnet.technic)

(...) Yes! In the old days before the black ones appeared, making and bracing large structures with the grey pins was "interesting" as said structures would be prone to an incredible amount of rattle and cumulative flexibility. The black pins really (...) (24 years ago, 15-Mar-01, to lugnet.technic)

(...) Yeah, I noticed that too. I've actually started (gulp!) distorting those loose 8t gears by resting them on a couple of teth & squeezing - you've gotta becareful no to squeeze too much! Also a few of my 8t have cracked (not the ones I (...) (24 years ago, 16-Mar-01, to lugnet.technic)
