Been a year since I've done anything on this build.
Chassis turned out to be twisted, so I totally rebuilt it. The Professor Motor bracket's pre-machined flanks accepting round or square brass main rails didn't match hence different rail planes. A bit of filing fixed that and the 3/32" square main rails were replaced with 1/8". The guide tongue was kept but everything else is new. This was a chance to try out a Piranha motor so that was installed keeping the 3:1 gear ration with 9t pinion and 27t crown gears.
I've now gone for more of a street look so the body's been lowered. Smaller front tires have been mounted to accentuate that look.
Will run this in our American Iron class at GVSCC.
