Backhead and under the hood for the Dick Kerr 10

I've been busy on the Dick Kerr, mainly working on the "backhead" and technical items.  The detail in the above image looks crude, until you consider how small this little loco is, the cab could be mistaken for an HO scale RS3, and the interior here shown is just a fraction of that.  I've made a couple compromises, but, they should not be noticable through the cab door.

I've also designed a set of spur gears for the revised Mechanism.  The real work was done using the fantastic program Gearotic Motion.  I was originally planning to machine these with the Roland mill, but I am going to use these to put the Form 2 to the test today.  Any significant distortion will cause problems with these small gear of 9mm and 14mm diameter.  If they don't work I can always make them on the Roland.  If they do work, I may need to cast them in a softer plastic.  We'll see.

Bruce Wilson proposed a set up from Hollywood Foundry that looks very good--I may go ahead and make one of my mechanisms, and order a Hollywood Foundry item for the second, just to make the body adaptable to something that is not as custom as my solution.
