No, but I'm really intrigued. Where can I get my hands on one?

As I had mentioned in an earlier post, 5-40 is the same diameter as the existing hole and if you buy them long enough in an Allen head there will be an unthreaded portion for the arm to ride on. Cut off the excess. I used 4-40 nyloc nuts tapped to 5-40, just because they where smaller, but work perfectly for the job.

Clay I found that while looking at some underwater photog stuff.

I would think even std ball joints would work well as you really only need to move in one plane.

Tolerences will be tighter and eliminate the linkage jamming up?

A bit expensive but similar to these

Even an end rod bearing that can go 360 degrees front and back and limited left to right movement.

I've got something just like that that I'm working on (I think taken from your previous post):






I'd need to incorporate a could of changes to make it all work, most notably a way to lock the piece in place. I've got a couple different competing ideas about that. I'm interested in everyone's thoughts.

For those of you that want to perform your own home brew mod on this issue I posted a picture essay documenting my soulition using Automotive Feeler guages. It took about 1 hour and a $5 investment. Untill WE comes up with a new re-designed arm assembly, I am happy with this home brew mod.

Thank you for posting your mod, it's a very nice and elegant solution!

Clay I was thinking the end rod bearing would go into where the linkage is so no real mods have to be done to the unit. To basically replace the black part and the other joint.

Hope it is ok I used one of your pic's

I'm looking at this now, but not sure if there would be adequate range of motion with the middle rod running through it in that dimension. It looks like it would need to be rotated 90 degrees to get the proper range of motion.
