The High Level tender chassis installed in the Bachmann frames.
The screws are 1mm x 3mm self-tappers soldered to 12BA brass washers. They fit nicely into existing holes in the frames moulding.

The frames just interference fit into the body, no attachment needed.
Could be from the High Level website.... but isn't.

For Mike G. My CSB notes for the loco chassis. This part of the build was relatively easy, but the vacuum pump assembly had to be sacrificed to make way for the spring wires. I found other ways to make the build more difficult..
Chris designed the loco chassis to be driven from the rear axle as did Bachmann, and unusually designed the compensated rear axle to carry the motor/gearbox assembly. I found out later why.. No CSBs for the loco, I couldn't have that!
The design intended that the front axle should be rigid, whether the whole lot was, or compensation was chosen. Had I not taken the same route as Flymo with his 48xx, and decided that the optional valve gear assemblies could not be left off with so much space under the boiler, I would never have understood Chris's reason for the rigid front axle... a sprung one fouls the valve gear. Not by much, but enough to inhibit the running - possibly.
Fortunately, I have in the distant past used the old Exactoscale gearboxes with 2mm axles, and saved the 2mm x 1/8" sleeves. A pair of those were fitted to a 2mm axle and shortened so that they stay within the wheel and the bearing, so the axle now clears the valve gear.
I am also not happy to drive an axle that wasn't driven in the prototype, so another deviation from Chris's instructions (and gearbox) was called for.
Some of these deviations haven't been fully road tested yet, so if they work, later...
Ted.
