Had to bend the brass sheet leaving an 1/8” between the sides and the loco framing.
This will allow insulation on top on the cylinders and make it easier to clean out the ash.
This job worked out a little bit more complicated than expected.
I also had to fit an extra piece underneath the tray as the front seal.
The brass short piece, which is between the two exhaust, I can either leave it as it is right now or cut it away. The advantage of cutting it away would allow the smokebox to be removed at a later date without disturbing the blast pipe.
It looks neat at the moment and once the loco is finished I do not think I will be removing the smokebox anyway.
Finished for the day. Made good progress.
Photo from the cab end. The tray has a gap 5/32” between the sides and the framing for 1/8” smokebox wrapper.
Time for dinner!
One other supplier had similar rings, but out of stock and their foundry is closed due to the lockdown.
The rings are from a 7 1/4 “ gauge Mogul but looking at the drawing I should be able to machine them to my sizes (I hope).
All good fun!
