I'm envisaging you have two 0.7mm wires, each secured to the tiebar, and descending through an unknown length into tubes. It's not clear what the tubes are attached to, nor how that below-baseboard attachment is linked to or mounted on the Tortoise.
I didn't include any pictures because there is already a picture of the P4 Track Company's adaptor plates for Tortoise motors earlier in this thread (see Merlin46's posting on 8 August 2008). I should have pointed this out since people can hardly be expected to remember a posting nine months ago. Sorry! By the way, why is there no emoticon for 'embarrassed'?
The adaptor plates are made from some type of plastic and the bottom of the brass tube is secured in holes in the bar that is moved from side to side in a channel in the adaptor plate just below the baseboard by the operating rod of the Tortoise motor. I think the diagrams and photos in Merlin46's posting should make it clear. The two 0.7mm wires are soldered to the 'ears' of the tie-bar and descend, as you surmised, Russ, into the tubes. My question is how much side-play there ought to be between the wires and the tube and how critical the amount of side-play might be.
