Diode Voltage Droppers for Ringfield Motor Upgrades & Conversions

If you’re using a 6V dc motor in your Lima or Hornby ringfield motor conversion, and you’re using DC control or DCC without CV5 functionality, you’ll need to consider a diode voltage dropper to protect the motor from over-voltage and current.

Diode Voltage Dropper Components

I’ve always made my own, but I know that not everyone has the skills, confidence or time to do that too, so I’ve come up with a couple of wee kits to help out.

Preassembled diode voltage dropper kit

There’s a pre-assembled diode voltage dropper kit which includes all of the core components soldered together for immediate use, plus a ‘components only’ kit with everything you need to quickly knock one up yourself.

If you’re interested, you’ll find the pre-made ones here and the components-only kits here.

You’ll find wiring instructions in the following booklet…

The world’s first adjustable Lima motor adaptor is here!

Next up from the Strathpeffer Junction 3D printer: an adjustable ‘generic’ ringfield motor adaptor for Lima locos.

Adjustable Lima motor adaptor

Following a few different queries from subscribers and viewers, and after a fair bit of testing and tweaking, we’re pleased to reveal my brand new adjustable Lima motor adaptor.

Adjustable Lima motor adaptor works with most 12mm CD motors

It’ll work with most small CD or DVD drive motors, from around 9mm to 12mm thick and 24mm diameter (or thereby), and is a simple ‘plug and play’ solution, just like the others in the range.

We’ve put together a brief overview and installation tutorial, which you can watch below.

Lima Replacement Motor Adaptor: Finding the Perfect Fit!

Another short video relating to our Lima motor conversion kits.

Today we’re having a look at two alternative techniques for improving the fit between our ringfield motor adaptors and the CD drive motors that go in them.

Normally, the motor will fit into the adaptor with a good interference fit and will sit snugly, but sometimes manufacturing tolerances mean there may be a little play.

The two featured options resolve that issue for good, and take only seconds to do:

    • 01:01 – Method 1 (Permanent)
    • 03:01 – Method 2 (Reversible – Preferred Option)
