The chassis has been started... for heavy duty work I decided that a six wheel chassis was required.
Side frames from 1.5mm styrene.
Still needs axle boxes.
Romford brass pin point bearings.
Wheels ... turned wheels with insulating axle muff. (Walthers #933-870)
( nd no its not dead, just laying on its back to get the sun.)
Top view showing where the gear will fit.
By using the brass bearings and the wheels that I have chosen it only needs a thin wire soldered to the bearings to provide power to the DCC chip.
This photo shows the chassis with the power wires coming through the floor and also the two motors with gearheads that I intend to use.
The only (major) problem is that the motors are 3 volts only and DCC is about 12 volts.
Not yet sure what the crane itself will look like but have a few ideas.
Guess that it will just grow, like most of my creations.
I have already built a working crane in SM32 (1/19th on32mm track) but that had an enclosed cab and was a lot bigger all-round.
Must admit that I like the idea of the operator sitting on the actual 'crane' and having a steam/petrol engine to do the hard work.
