Progress has been slow this weekend, but a mystery has been unravelled.
You may recall that when I started the footplate, I couldn’t find two out of four part 60’s? Well today I found them…
I started yesterday’s session by rolling the boiler and it mentions using part 52 to ensure that it’s round.
This is the drawing of part 52
I found it amongst the remaining bits of etch and tried it in the boiler all was well.
Then I started to assemble the inner support frame for the boiler using the diagram below and photos of my previous build.
In my previous build I hadn’t used part 52… so I started questioning why not.
Although I obviously hadn’t worked it out before due to lack of experience it quickly became apparent that there was something wrong with part 52.
The photo above shows both sides of part 52 as etched. Although it’s one piece when you check against the drawing snip above it should in fact be three parts, 52 and 2 x part 60 (the missing parts). It looks like when he drew the artwork Garth Patrick got these bits on the wrong layers and the bit’s that should have been etched though have been half etched on one side and the outer ring which should have been full thickness has been half etched on the back making the part completely useless. I contemplated cutting the ring out with the piercing saw but I obviously managed without it on my build so could on this. As it happens in my spare etch box I found a semi circle the correct diameter which I will attach with a couple of bits of scrap to support the firebox end of the boiler tube.
Photos to follow once I have done it.
