This week I have another product update to share with you. Unlike last week’s update, for the Minitrix eccentric rod crankpin, which was driven by improving the part, this time it’s simply about reducing the cost to you.
For many years I’ve offered N scale and N Gauge fixed link couplings or drawbars to use between rolling stock or, as I like to use them, between multiple diesels that stay coupled together. This is really useful if you install a DCC decoder in one locomotive which drives both motors, you can read more about that here. These drawbars are designed to fit into the Rapido style coupling pockets as you can see below.
To start with these couplings were offered in Shapeways FD (Frosted Detail) material but as that was removed from the available materials they automatically became available in FUD (Frosted Ultra Detail) and sadly the cost went up a bit. When Shapeways restructured their material pricing again back in June of 2017 these became rather expensive. However, just as with the Minitrix crank pins from last week I’ve combined the fixed links or drawbars into one piece making them much cheaper to order, as you can see below.
And I’ve also made the primary material BNVP (Black Natural Versatile Plastic) formally known as Black Strong & Flexible. This is one of the cheaper materials; it’s already a good color for a coupling and can be used right out of the box. Below you can see a set I’ve already ordered.
These are available in a variety of lengths and all come in packs of 6:
And if you’re not sure which lengths you need I do have two sample packs available:
Basic Sample Set – Containing 4mm, 5mm, 6mm, 6.5mm, 7mm, 8mm & 9mm.
Full Sample Set – Containing 4mm, 5mm, 6mm, 6.5mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm & 13mm.
The length refers to the distance from the inside of the coupling pocket, for instance the 12mm is measured like this:
Next week I’ll have some real steam to share with you as I spent a day at ‘The Great Dorset Steam Fair 2018’.
