These adaptors enable you to quickly replace aged ringfield motors in OO gauge models with CD-type motors, without the need for any messing around with glue or fiddly shaft alignment.
You simply remove the old motor and gear, pop the new motor into the adaptor, trim down the new gear and fit it onto the shaft, and then install the new assembly into the motor bogie. Everything is lined up and ready to go!
Finishing touches are also being made to a Hornby ringfield adaptor – it’s a more complex design, but works equally as well on testing. There’s a little more testing to be done, but these should be ready in the Spring. Stay tuned…
In our last blog post, looked at the TCS-brand 21-pin breakout board, which can be used to permanentconvert an 8-pin DCC decoder for use in a 21-pin chassis.
We’ve now put together a short YouTube video on how to carry out the modification, which you can watch below. We’ve also produced a wiring diagram to accompany the tutorial, which is available by clicking here.
In that video, we used a LaisDCC 21 to 8-pin adaptor, customised by removing the 8-pin socket, to allow the decoder to be plugged into a Bachmann Class 47.
While that method is still totally valid and remains the cheapest option (as of today’s prices), we have subsequently discovered a TCS-brand 21-pin breakout board which can be used for the same purpose.
These TCS adaptors are more expensive than the method outlined in our earlier video, but easier to use and require no real preparation. They only come in packs of five, however, and at about £20 per pack, if you only need one, they’re pricey.
We’ll probably do a quick video follow up in due course as we have another TTS chip to convert, but for the time being, as we’ve yet to find any instructions online, here’s a pin-out wiring diagram for the TCS 21-pin adaptor…
