Hi Gang

Just a quick update on the 7mm Z20 Class, I have been working on the Pony Trucks , and have included a
couple of images for you to view

 I have also looked at a new method of design for the buffer pots. One of the problems with the Z20 Class is that the buffer heads interfere with the air tanks on the rear and the frame work in the front, so by designing the buffer pots to be self contained, the buffer head shafts are changed from round to square and with a cut out in the shaft, with a 0.8 mm pin located under the buffer, and placed to locate in the cut out, with a spring at the blind end of the buffer, thus allowing spring action to occur. Please let me know what you think, or if you can so problems occurring, have a look at the images below.
