Tender springs
Tender spring and hangers assembled on the chassis. I need to decide on the use of rivets or turned down screws, as used on top right position of right hanger. Also the real spring, hidden, needs to be added still.

Spring hangers for the Tender
These come as a collection of tiny parts from Model Engineering Laser. See below, each hanger is made from 5 parts. And 12 hangers in total. Cut them apart, file them clean, and do a test assembly. This is followed by silver soldering each, using 0.9 mm silver solder, and …
Start of the New Year 2020
I took the Britannia to the track during the New Year party of Rading Spoor, see also radingspoor.nl . I wanted to test the position of the brake beams and the bogie wheels in the curves of the track. No problem there. And a nice picture of her:
Britannia’s Boiler arrived
This week I picked up the boiler for my Britannia, custom built by Ryan at Steamtechnologies, in Cranbrook, Kent, UK. See also http://www.steamtechnology.co.uk/. They did a fantastic job ! When arriving home, I did a first test to get an impression of the boiler and the locomotive: Still a lot …
Britannia running on air on both cylinders !
After testing the two cylinders separately to run on compressed air, I started to test both connected. This took some more efforts in preventing leakages in the connections and the valve bobbins. Today both cylinders were running, both forward and backwards, on compressed air. They still need too much air, …
Test ride on Rading Spoor track
We had a club meeting today at our Model Engineering Society “Rading Spoor” in the Netherlands, see www.radingspoor.nl (in Dutch). I took the Britannia with me to see how the motion work moves on a real track. Here she is after the test in the sun on our track:
Right cylinder runs on air as well !
A month after the left cylinder was running on air, the right cylinder was ready for a test run as well. I decoupled the left connecting rod, and tested the right cylinder stand-alone. After some attempts it started to run, but only with a high air pressure, and loosing a …
First run on air !
After building the cylinders, most of the motionwork, and a lot of assembly and disassembly, and assembly again, I had a first successfull test run on compressed air. With only the left cylinder connected, it started to run reasonable good. See this clip:
Water Pump Design
The Water Feed Pump is a re-design, based upon the original design of LSBC, including the pump-castings, and a better guidance for the plunger, based upon designs from Dutch and German models. More details to be added.
Exhaust Pipes
The exhaust pipes from both cylinders to the smokebox consist of two 8mm pipes flowing together into one 10mm pipe into the smokebox. The work consisted of bending the pipes, with my miniature pipe bender, removing the top half of both pipes, turning and milling the two small flanges, and …
