i to have had a similar problem involving a scaled-down version of some of
the big mech joints, and your problem has reminded me of a version i
scrapped a few months ago. try getting some of the flex tubing that can be
found in the anikins podracer set, and putting that into the firction axel,
it will be hard to get in and it is a perminent fix, but it migh just
provide you with the needed hold that you require to keep that sucker in its
girder block.

alternately you could try to make your entir design big enough to fit the
transmission block on, but that would mean you would have to start from scratch

sorry bud, this is all i can do to help ya

   I'm working on a secret [read:unworthy] project and have been trying to
think of achieving a certain type of motion without success.  I'll try to
describe it:  The motion/mechanism I'm looking for needs to be able to
achieve some sort of discrete-step motion linearly.  The closest thing I've
seen in Lego is the shift mechansim in the transmissions of the big lego
technic cars.  The part that actually engages the gears in the transmission
(and hence a clutch as well as a shift) is fitted over an axel joiner.  This
allows the clutch/shift to move back and forth in discrete steps.  I'm
looking to replicate this sort of motion on a small scale and I'm totally
stumped.    The long pin with friction provides a little bit of what I'm
talking about but only one way...pull it the wrong way and the pin might
come out!  Anyway...suggestion will be terrifically welcome.  Thanks :)

Interesting solution! I had tried the long pins and found that the end I wanted to stay stayed for the most part...but it wasn't reliable. Increasing the friction of one end is a novel idea indeed. I may just use it in the end. The option of making (...) (22 years ago, 9-Aug-02, to lugnet.build.mecha)
  Re: slide-click joints
 
(...) I think this is a great suggestion for what Luke is trying to accomplish. Just place the tubing in the center of two long friction axels. If flex tubing gives you too much flex, you could alternatively use the 4L lightsaber blades in it's (...) (22 years ago, 9-Aug-02, to lugnet.build.mecha)
