CA5 LOCO CHASSIS

0-6-0/0-4-0 Chassis £8.50
LOco Chassis

 

loco chassis diagram

The chassis consists of two plastic sideframes and three metal spacers, motor mounting plate, two movable pieces for body fixing. The motor (not supplied) can be fitted in one of 3 positions (1 vertical, 2 angled). Motors CA2, CA15 & CA17 below are suitable. The non-powered axle positions provide a choice of wheelbases, suitable for a variety of common steam & diesel prototypes. It is suggested that a "cosmetic" plasticard overlay of the shape and length suitable for the chosen prototype, is added to the sides of the chassis behind the wheels. Includes six x 1/8" brass bearings; requires motor / wheels / gears to complete.
The plastic sideframes are 139mm long x 20mm deep. The chassis is 25·5mm wide over the frames.
2mm axle bearings can supplied instead of 1/8" ones, if requested when ordering.

GEAR BOXES

        Motor and gearbox

These are 3D printed in ABS (colour may vary), and include CA1 or CA3 gears (details under GEARS below), two 1/8" brass bearings, 2 motor fixing screws and CA2 Large or CA17 Medium motor (details under MOTORS below). The gearbox dimensions are: 22·5mm wide, 25mm high and 15mm front to back. Ribs in the box locate the gear under the worm. There are "blind" holes in the back & base for mounting screws (not supplied).
The "axle" shown in the picture is not included. Higher rate postage applies to all gearboxes with motors.

CD1 Large Motor, 30:1 Gears          £15.25

CD2 Large Motor, 40:1 Gears          £15.25

CD3 Medium Motor, 30:1 Gears     £14.70

CD4 Medium Motor, 40:1 Gears     £14.70

CD5 & CD7 include CA23 gears for 2mm axles; CD6 & CD8 include CA21 gears for 2mm axles (details under GEARS below)

CD5 Large Motor, 30:1 Gears          £15.65

CD6 Large Motor, 40:1 Gears          £15.65

CD7 Medium Motor, 30:1 Gears     £15.10

CD8 Medium Motor, 40:1 Gears     £15.10

GEARBOXES FOR IP ENGINEERING CHASSIS

      3 gearboxes

A replacement for the one supplied with the IP Engineering Chassis. 17·5 x 15 x 37·5mm high. It fits between the bosses on IP wheels. Includes 2 brass bearings for 1/8" axles & motor (CA24) fixing screws. CD10/11 fixing lugs can be attached to the chassis cross-member. For suitable motor and gears, see CA24, CA25 & CA26 below.

CD9 Side fixing lugs        £7.25

CD10 Single central end fixing lug    £7.25

CD11 Twin end fixing lugs                £7.25

The lugs are "outside" the gearbox width on CD11.

GEARS

When choosing gears, the track speed of the loco will depend on the motor speed
– which will be affected by the voltage supplied and the weight of the loco/train;
and the size of the wheels – smaller wheels = lower speed (but more "power"), larger wheels = higher speed.

CA1 40:1 Gears (Metal) £6.90

  Steel worm for 2mm motor shaft, brass gear for 1/8" axle.

CA3 30:1 Gears (Metal) £6.90

  Steel worm for 2mm motor shaft, brass gear for 1/8" axle.

CA4 20:1 Gears (Metal) £6.90

  Steel worm for 2mm motor shaft, brass gear for 2mm axle.

CA8 20:1 Gears (Metal) £6.90

  Steel worm for 2mm motor shaft, brass gear for 1/8" axle.

CA21 40:1 Gears (Metal) £7.30

  Steel worm for 2mm motor shaft, brass gear for 2mm axle.

CA23 30:1 Gears (Metal) £7.30

  Steel worm for 2mm motor shaft, brass gear for 2mm axle.

CA25 30:1 Gears (Metal) £7.90

  Steel worm for 2·3mm motor shaft, brass gear for 1/8" axle.

CA26 40:1 Gears (Metal) £7.90

  Steel worm for 2·3mm motor shaft, brass gear for 1/8" axle.

CA9   2 Plastic Gear sets 16:1, 2mm bore £1.00
CA14 2 Plastic Gear sets 30:1, 2mm bore £1.00p
CA16 2 Plastic Gear sets 42:1, 2mm bore £1.00

The plastic gears can be carefully drilled out for 1/8" axles. We do not recommended attempting to enlarge the bore of the brass gears.

MOTORS/BEARINGS

The motors listed below (except CA24) can all be run on 1½ volts to 4½ volts,
although above 3 volts they will probably run too fast for the usual speed of narrow gauge locomotives.
L = length over body, excluding the boss round the shaft.
D = diameter over body.
W = width across flat part (CA18). ** Higher postage rate applies to all motors, except CA18 **

CA2 "Large" Motor, 2mm shaft £2.00

12mm x 2mm shaft, L 30·5mm, D 24·1mm

CA15 Smaller Round Motor, 2mm shaft £1.50
