Guys, thanks for all the kind comments on my project, this is my latest progress.
I installed the spoked wheel covers, and the connecting rods using the rivets and the small caps from the TGauge.com valve gear sheet. Just by cutting the rivet it held the cap in place. However, I added the smallest drop of CA just to be sure it will hold up over time. Working with these small parts is insane work. I am calling it Extreme Steam Craziness.You need extra rivets and other parts as you are bound to lose some during assembly!
I also learned lots more from my tests with the 3.2mm motor. The rear magnets are very close to it, and seem to have an effect on the locomotives performance. I placed the magnetic rings from the rear wheels on my soldering iron for a few seconds, and that demagnetized them. Placed them back on the wheels, and the locomotive is running very well at this time. In fact I found that all the model really needs it two wheels with the magnetic rings to be efficient. I am using them on the center wheels on my first prototype, the other wheels have rings that are demagnetized. This is with the 3.2mm motor. The 4mm motor has more power and may work better with them. I plan on building a second model with a 4mm motor to test this out when I get time.
Hope this information helps.
Joe.
