murrayec Posted February 27, 2023 Posted February 27, 2023 This is a Leinster Models Class A Gauge O, someone took it apart to do some repairs but never got it finished! The motor mounting bracket needs to be machined and fitted, new electrical pickup system to be installed, and the lot wired up to run. The bits as delivered. The motor mounting bracket was drilled for the motor and bolt mounted on that block of brass between the frames. Axles being setup with spacers to keep the gears on centre. After setting up the drive gears the motor was installed to find the motor gear wheel had been drilled out off centre, this causing a massive wobble! The photo shows the gear wheel held in a collet chuck on the lathe and the centred hole being bored out oversize to take a brass sleeve to fit the motor shaft. Drive gear finished with brass sleeve pushed in with a bit of Loctite. The sleeve has a hole drilled in it to allow the grub screw to pass and lock on the motor shaft flat. Runs smoothly now. Setting up the front bogie for electrical pickups- first a slot was machined in the top of the bogie, with a screw installed in the chassis to stop the bogie rotating to much when mounted and damaging the wiring! Soldering in two cross frames to hold the pickup board. Cleaned up and mounting holes drilled and tapped. .6mm NS wire was used for the pickup wires. Pickups complete. Wiring complete, with a DCC 8 pin socket installed. Chassis under test on completion. I forgot to take a photo with the body on! Eoin. 13 1 Quote
