How about graphite? I don't think that will degrade
plastic.

Why not? Graphite's carbon rings are most definitely not going to harm
ABS plastic. Is it a purism thing?

Oil may work well on turntables, but don't use them for pneumatics. I oiled them
with some kind of oil (I can't remember), and now they stick and stutter when you
pull them. They seem to operate fine now, but not if they get much worse. I would
not use any oil, just pop them open and clean them. You may damage the part
irreversibly, and turntables are hard to replace cheaply. Graphite should be safe,
but you never know...

Why would one "never know"? This is chemistry, not astrology. Graphene
sheets (the molecular unit of graphite) are quite stable and inert.
Most hydrocarbon oils should also be fine for turntables and other parts
with all-ABS construction (although permanent surface discoloration is a
distinct possibility). I've never disassembled any pneumatic elements,
but do they have any sort of rubber bushings in them? Many oils could
definitely injure such components, rendering them brittle and tacky.

You got me pegged, it's a purism thing, I pride myself on never cutting or
altering pieces, glueing or lubricating. Just work those pieces and they'll
loosen up! Get'em... GRRRRR....Eric

That's okay, I'm a purist too. I once spent several frustrating hours
completely redesigning the drivetrain on one of my robots so I wouldn't
have to trim down four 8L cross axles to 7L. However, when you consider
lubricating a turntable versus breaking it in, you actually may be
modifying the turntable less by lubricating it than you would by
breaking it in. After all, if the turntable turns more easily after
break-in, there has technically been some degree of modification to the
part, probably a slight planing on the contact surfaces that might not
otherwise occur if the turntable were lubricated.

Good point, well taken, I'm glad at least 5L axle was produced!

Graphite could work, and should be safe. I've been using it for model train
couplers, which are made from Delrin. It comes in a little tube, and you
sort of "puff" it on. Kadee is the manufacturer, and it should be available
in the model train section of hobby stores. It stains anything it comes in
contact with.
When I worked with Fischer Technik, I used petroleum jelly a lot. Fischer
Technik is made from Nylon.
