I was speaking to Steph the other day, rather conscious that I had left this drift a bit, and he said 'just smash it together so I know it works'.
Now, I had to look up 'smash it together', and I found it meant 'meticulously craft to the best of your ability'
Joking aside, there are 2 conflicting imperatives here. All Steph wants to know is that the geometry works, everything fits, and there are no fusterclucks along the way. Decusping and careful soldering are simply not relevant. However, for the stand, we want something to impress, so customers go 'Wow, I'll take a dozen!' Those imperatives are at the opposite ends of the spectrum.
So, I'm taking a lot of time off between now and Doncaster, so I can finish off the chassis, including inside valve gear (part of the test etch) to my satisfaction, but also to enable me to say to Steph at Doncaster.....'We're good to go!' Hopefully, he will provide some 3DP parts for the 4 or so castings that are not in our current range. Other than that, I can use mostly the T9 castings to dress the model.
There is a huge family resemblance in the chassis construction from the Adams' Radial and T3, through to the L11 and T9, So much so that I can do it without instructions, which is just as well as they haven't been written yet. I do have a GA in the book of the Drummond Greyhounds however.
Bogie first of all, necessary now as the chassis cannot be set up without it - the bogie pivot is the 3rd point of the compensation system.
