Great set of links -  unfortunately the Flickr "irish railway archive" ones are all restricted access.

...and they are many of the best ones. You need to join the IRRS!

That’s a great close up. For brass workers like me, it’s also a reassuring proof that platework on the real thing could also be shonky. Check out that front splasher on 655, and as for the gap in the boiler cladding….

Here's 663, the cladding doesn't look too bad on this side but it still looks like it's been dented by some fat fingers and clumsy handling:

But these IRRS photos of the other side show that a whole cladding sheet has come loose and seems to be flapping about:

The loco is still in steam and in use. A few months later it was withdrawn and sat on the scrap line in Athlone with that cladding even more bent out of shape:

What a wreck! 

 

Note that 663 above carried a round-top boiler but had the larger diameter, waisted smokebox normally seen on the Belpaire boilered locos. It's quite a different shape to the almost flat-sided smokeboxes on 654 and 655:

Back to Quartertown Mill, I've been playing with the CAD and laser-cutter to rough out a platform and mill building shape.

I was delighted to find that a local stationers stocks good quality 1.5mm card for a few quid per A1 sheet, which is ideal material for this sort of exercise.

This is truly a job for the lazy man's scalpel!

I'll do similar rough mockups of the other buildings to get a feel for how they look, and if the layout seems balanced. At present I've just estimated dimensions from maps and photos, so there is certainly scope for some tweaks. 

Once I'm happy I can use the rough CAD as a basis for the more detailed and robust structures.
