I know I'm a little dense at times, and some would say as thick as two short planks, but I can read, and if you start at the beginning of the thread, Pipster, you will see that it ALL has been built from scratch as far as I can see.
What is the point in a person taking the time to write and photograph a build thread if people are not going to read it from the beginning before asking questions!.

He asked a resonable question about the ram as I did not show how it was made because I forgot to take pictures, which if I had done I would have posted them. It hasn't all been built from scratch e.g. the gearboxes and tracks.
Looking fantastic!
Did you make the main ram yourself? If not what is it and where did you get it from?

The ram is made from styrene tubes, an M3 nut and threaded rod and a very small high torque motor gearbox combination.
When power is applied to the motor the rod rotates and the nut runs up it taking the inner ram with it, Reverse the power supply and the nut comes back down the rod contracting the ram into the outer casing.
Hope this sketch makes it clear.
