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

For all of those modellers who have paid a deposit for the Z20 Class loco kit, thanks you for your patience and solidarity, there is a light at the end of the tunnel, and that light will be shining on 31^st March 2011 at the 7mm Forum at North Sydney Leagues Club.

For those who may be interested in a NSWGR Z20 Class Steam Locomotive Kit in 7mm. The kit is based on the Z20 A/E as built at Eveleigh.Living at Picton and having 2029 at Thirlmere can certainly make things a little easier when needing to compare drawings to the real deal.

You can secure one of the price of $999.00, up until the release date by sending a deposit of $200.00, to

The instructions will be published on Keiran Ryan Models web site prior to the kit being released.

I will be releasing drawings of components as they are finished, so that you  can see that we are getting closer to the finished kit.

Now back to work with the kit development.

Welcome to my 7mm NSWGR Z20 Class Locomotive Blog

Welcome

This blog has been set up, to keep modellers informed as to the progress of the NSWGR Z20 Class Locomotive Kit, in 7mm Scale.
The kit has been a long time in the making and is now getting closer to being realised. For those who have had deposits on the kit, thank you for you patience and solidarity, through this design and development process, and I will be attempting to make the wait very worth while.
