@smokey2 or exxcommon
I appologise for my ignorance in addvance.
Since I decided to allow my self to be distracted and have a crack at this could you point me to the design criteria for the linear bearings.
Kind Regards

The convo and concept are here:
http://www.overunity.com/index.php?topic=4540.msg103520#msg103520

and here are some of the drawings of how it MIGHT look, but this is not the same as smoky2's. He modified the design to suit a square rod instead of a circular one.

@exx

actually, i didnt change the bearings at all.
i can interchange a square or round rod, exactly how you picture them above. the only change i made was that i used brass rod instead of AllThread, i found that the bearings seat better.
and i used wooden cornerblocks to hold the things together.

I cut some junk metal for  torque-proofing my outer rod.
these will go in the bearing track of the outer rod, to help protect the wood, and hopefully reduce binding.

Thanks Exxcommon and Smokey 2. I have a good idea re the bearings now....simple but elegant.
I will let you know how I progress. I will be in the capital city Brisbane next week so can pick up a few supplies. (I quit smoking a few weeks ago and am going to use the money saved for my hobby, at $15 per packet in Australia that's a lot i can spend now)
After I made some progress on this I have another idea of using gravity and magnets, but it is linear. I have seen many (Non working) attempts around the world over the years and what you produced smokey is up there with the best of them. I do hope you manage to get it running again as there is so much to learn from what you already have achieved.
Kind Regards

the credit for this invention goes to Archer Quinn
i just recreated his original design. making minor adaptations to fit whatever junk parts i decided to use.
