I am now trying to work out how the crosshead goes together and have made a drawing of what I can see and I will be going back to the engine house next week to photograph and take more measurements ...

Take a big wrench, and send any others there out for snacks while you take it apart...!

Thanks Dave , and I have made a perspex mock-up as to how I think it should go together .. the piston rod will screw into the crosshead and the large nut acts like a lock nut, and the thread does not show and the nut has a recessed portion that goes over the piston rod to make things look neat and tidy !!! the latest drawing is just a sketch and a proper one will be drawn when I have more dimensions..

So more work on the crosshead and the crankshaft end is started on and the part is carved out of one piece and when made the bearings are inserted from the inside. it is then offered up to the crosshead and the central pin is inserted through it . this pin is then held in place by tightening up the two nuts either side of it. there is a hole on the top of the crosshead   ?/ for lubrication to the bearings but there must be some internal channels to get the lubricant to the central rod  rather like the drilled holes in a crank on an IC engine.   looking at the photos it looks like there's a brass?? bush between the pin and the slideing part ??  So  a few more pics to see how it all fits ...

Wow, some good work on the perspex version. Ever consider just painting it steel color?!

I agree with Chris ... That is nice work with the perspex!
I was cut out to be rich ... but ... I was sown up all wrong!
