Next job is to get the motor in place and see if it runs!

Some progress on Mr. B's (husband to loyal blog reader Mrs. B) re-mototing of his beloved Triang Hornby Britannia. The new motor is not quite a slide in simple replacement as there is a need to rewire things.

First off a wire needed to be soldered to the underside of the motor and then to a tag which replaces the all live chassis pickup of the old motor.

Next up the old motor and syncro-smoke unit were removed from the chassis.

I had never seen the inside of one of these smoke units that were a fad in the 1970s. There is a small heating element that is supposed to heat up the oil soaked fibre and the cog drivers a puffer to emit smoke from the locos chimney.  Looking at that fibre and seeing that the unit got surprisingly hot on the outside during my previous testing I thought that to avoid a possible fire it would be better to disconnect the unit. I would leave the unit and wiring in place though just in case Mr. b really wanted this feature working.

Turning the loco over I removed the base plate so that I could solder the wire on for the other part of the motor.

  1. Well, Mrs B didn’t know about the smoke either, however has now been educated by Mr B and report that this is more of a very feeble wisp, than a full blown smoking chimney. Blink and it only be sniffed.

    1. It had its moment as they say in history books! However there is a new generation of smoke generators which is probably best described in this video which if Mr. B sees he will quite probably want! You have been warned! https://www.youtube.com/watch?v=juXDd0x0Bdc
