Class G2 Gauge O Chassis Work

[murrayec]

A Class G2 chassis required coupler rods, brakes, wheel weights and electrical pick-ups.

On arrival, with brass etched rods and brake shoes- though I'm using my own Tufnol shoes as these insulate the wheels and one can have them right up against the tyres!

After a plan of action was worked out the parts were cut- brake hangers/rods and wheel weights from .35mm brass sheet, pcb board was machined for the pick-ups and the Tufnol shoes.

Milling flats on the frame spacers to provide a seat for the pick-up boards, the frames were also drilled for the mounting pins which hold the brake shoe hangers.

Brake parts almost assembled.

Soldering the laminate coupler rods and cross brake rods.

Wheel weights epoxied on and a flat was milled on the motor axle to seat the gear wheel grub screw.

A 10x6mm dia brass rod downstand was made and bolted to the front frame spacer to provide a seating/fixing for the front axle pick-up board. The pins for the brake hangers were also soldered in. A 4mm long tube is soldered on the pins to hold the hangers in position.

Wheels back on, the brake gear was soldered up and the coupler rods fitted. The brakes are removable to access the wheels.

.45 NS wire pick-ups were bent up and soldered to the pcb plates and all was wired up to the motor.

And finally test running the completed chassis.

A few tweaks are still needed  on broaching out the coupler rod bearings, but it's ready to go off to it's crew for painting and fitting the body.
