for this try on Live Steam i used a boiler and oscillating engine bought at Lutz Hielscher.
Unfortunately no tech drawings of the components are available - so the shay was built from scratch and without any plans or drawings.
The wheels come from an old Kleinbahn chassis, two new chassis where milled out of solid brass. For low friction the axles are running in ball bearings. As the engine comes with a high transmission gearing, the gears on the wheels are fitted with the same count of teeth.
For the transmission from the engine to the boogies, two cardan shafts had to be manufactured - ready made brass profiles helped here a lot...
The frame also where made out of various brass profiles i found in my scratch box and soldered together.
Here the components are just fitted together loosely
First "steam up" - test drive
Great - generally it works - just have to tighten the screws, the transition almost fell apart after some turnarounds on the track.
So back to the workshop - adjusting the mechanics, and pimping the loko for a better look. So here are the results:
the transmission
