Building a 3D printed locomotive kit.
3D printing has come a long way during recent years and almost anything is available, or can be made on request.
I model in SM32, 16mm/ft. scale. All of my locomotives are battery powered and radio controlled using the Deltang based system.
This describes the preparation and construction of the PDF Models, Quarry Hunslet 0-4-0. The basic build information is available on Youtube, as with all of their kits. This one is the cabbed version of the Hunslet 'Port Class'.
The running plate is screwed to the frames, which are themselves screwed to spacers set to gauge. A little sanding is recommended to remove the printing lines and I do spend time doing so on all of the separate units. Filler primer also helps to check on high spots before final painting.
The wheels are metal and the 12-24v motor ( 3-6v is also available) comes complete with 30-1 reduction gearbox.
The firebox is well detailed and shows here how I have installed on/off/charge switch and basic wiring.
You can also see the chequer plate I decided to add on the running plate and cab floor.
It is desirable to paint components before assembly and here are the cab, saddle tank and boiler units painted and lined.
In the back sheet I fitted the charge point where it would be less noticeabl
The battery pack holds eight AA rechargeables, giving out 9.6v, ample for powerful slow running.

The surface finish I use is Halford's acrylic rattle-can clear lacquer, followed by their satin lacquer to soften it a little. Matt is also available if you prefer. My garden railway represents a preservation line so all of my locomotives are in clean and presentable condition to satisfy passengers.
This is just one of the three PDF Models kits I have built, including another 'Alice Class' Hunslet and a Double Fairlie, both of which for I made for friends....
I think Brian is happy with his!
It is with deep regret I announce that PDF Models have recently felt the loss of one of their founders, Peter Farley, who died suddenly, far too young. My understanding is that trading has resumed but possibly restricted in range and delivery. However, I highly recommend their kits which give superb appearance and performance, and are most reasonably priced.
