Having made them I figured it made sense to fit them before fitting other more vulnerable bits.
Not sure why since I have been concentrating on the left side of the loco so far but I started on the right hand side.
All went according to plan
Not so, on the left hand side. I can only assume that the wall thickness of the firebox castings is thinner on this side.
I couldn’t live with them as is so I had a choice attempt to file them down or remake them a bit shorter and put the longer ones in the spares box. Since I was still pretty much set up to make more, I elected for the latter.
Even with doing a test example to check that I had made the correct adjustments to my measurements it still took less than half an hour to make enough for the right hand side.
