Gearboxes and drive components

These components are all in my hopefully now-familiar approach of using strong and accurately-etched gearboxes in 0.7mm (0.028") nickel-silver which use ballraces instead of the brass bushings commonly found. Many of the motor-mounted variants of these gearboxes feature an (optional) motor shaft bearing to give additional support to the gearset; they typically include fixings for Canon 1833, Mashima 18xx, 16xx and 14xx motors.

More information including Application Notes, Planning Sheets and Instructions are available on the Downloads page.

  • Branchlines/Ultrascale-based gearboxes

    13:1, available in motor-mounted ('Power'), non-motor-mounted ('Remote') variants which I originally developed for diesel locomotive bogies. In either version the gears require a 2mm worm shaft and fit 3/16" diameter axles:

    Blines Power
    Full gearbox (unassembled) including fret, gears, bearings, instructions. £23.00ea.
    Assembled gearbox £40.00ea*
    For larger orders there is a price break at 18 units, please ask for more information if this interests you.

    Blines Remote
    Full gearbox (unassembled) including fret, gears, bearings, 2mm diamter worm shaft, instructions. £25.00ea.
    Assembled gearbox £40.00ea**
    For larger orders there is a price break at 21 units, please ask for more information if this interests you.

  • Romford-based gearboxes

    New Most useful for older or smaller prototypes, these gearboxes are available in 30:1, 40:1 and 54:1 ratios. The fret comes with two motor mounting plates which cover 10mm (Mashima 14xx and 16xx series), 12mm (Mashima 18xx series) and 15mm (Canon 1833) motor fixing centres. All gear sets take a 2mm motor shaft and a 3/16" axle. Please order by gear ratio.

    Rford 30:1, 40:1 or 50:1
    Full gearbox (unassembled) including fret, gears, bearings, instructions. £18.25ea.
    Assembled gearbox £40.00ea*
