Thanks Kim, this is beginning to feel more like jewelry, I think it would have so much easier in 3 1/2 inch gauge. I have completed the main work on the eccentric rods and am getting ready to begin the weight shaft and radius rods. the pins are just proxy keepers for the moment I need to make the proper ones with the taper pins to fix them, I am looking at #60 drill ish for the pins perhaps even smaller. :facepalm:

the weight shaft brackets are now fitted ready for the lifting arms which will be pinned to the shaft.

After three tries at making the weight shaft bends on different pieces I finally managed to get one looking decent enough. The arms were machined from some blanks parted off some 1144 bar stock. Now i know what folk are talking about regarding the stress relieved steel. The arms were assembled using a little jig, they have been set to the correct positions with some AC glue and are ready to get the taper pins added for securing them.

What is the purpose of the weight shaft?

Chris,
The weight shaft takes the motion of the Johnson bar or reverse lever and transmits it to the Allen links. The same shaft on a Shay runs parallel to the rail and is called the tumbling shaft.
