I WANT ONE!

When I do the next one I'm adding a second tube plate, say 20 mm from the front, or closer if you choose as it'll be a sliding wall inside the boiler.
I already have some thin wall tube, which is 1.20 mm OD / 1.00 mm ID and fits in the holes after a little twizzle with a broach. The real tubes are 2-1/16" which works out pretty close to 1.20 mm, the super heater tubes are 5-3/8" and the tube plate etch is 3.0 mm with cusp removed which is close enough for me. Macc models do a thin wall 3.00 mm tube with a wall thickness of 0.255 mm, Eileens too.
So. solder in from behind liberally and leave a small bit sticking out, then if the over thick wall bothers me I'll just tweak with a broach to thin the front rim, mind a 0.1 mm rim looks pretty decent anyway for the main tubes; but the super heater tubes might need opening out with a drill a bit first.
I already checked both sized holes in preparation and the etch was designed just in case I decided to visit JB in his padded cell
Or, you can just leave the door shut![]()

Surely an A5 is a Robinson engine - or at least a class for which engines were ordered under Gresley.

And Kings X for a short while too.The A5's were running out of Liverpool St for a short time whilst the turntable was out of action and covering for the Brit's..

An A8, oh b****r, rather like the look of them, actually a decent V1/3 would be v (more) useful and desirable.![]()
You're a very naughty boyWhat !.... no B17![]()
, we don't let all of the cats out of the bag at once

Seriously though, there's plenty of holes to fill first and the B17 is served by DJH which puts it in the secondary engines to consider.
