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.

Hi Gang.

Sorry about the in-action on the blog, but a heart attack in December slowed me down a little bit. But I am back in action, and will be getting this project back under way so that the kit can be released in October 2012.
The mind is a lot clearer now that blood is flowing to the brain at a much stronger rate, and better ways of doing things are becoming more apparent.
I hope to be able to make the building of this kit a much more pleasant experience, and an experience that will make the modeller want more kits of this type.
As stated at the Aus7 O Scale Forum on 24th March 2012 at North Sydney, I have promised that those modellers who have stayed with me in this endeavor, can be assured that the project will be released in October and if it is not, their $200.00 deposit will be taken of the price of the kit when it is released.

THIS IS MY COMMITMENT TO YOU.

Can't wait to get this project onto the market place.

So the good news starts now, with simple projects such as :
*          Marker lamps and headlights being designed so that they can easily be illuminated, with LED's or fiber optics (Your choice).
*          Components being bolted to the frames rather than soldered or glued (hence allowing for simple repairs and /or replacement if damaged)
*          Simple 8 pin plug included, with suggestions for DCC operations and sound options (DCC Ready)

*          Pre-planned location for speakers, including which type of speaker, and speaker enclosure, so that the most optimum sound and operation can be achieved.
*          Options for cowcatchers and headlight types to minimize costs in the basic kit (after market options)

*          Operating brakes, so that when the brake shoes wear out , you will need to buy more replacements form me.(OK, OK, that may be a littler over the top, but when the mind starts working, it is hard to stop).

Any how, enough of the talk, back to doing some solid work on the parts, thanks for your patience and looking forward to any comments or ideas, and more regular updates of this Blogg
