Giles,You NEVER cease to amaze me with your workmanship and microsurgery.
That's worth :moose::moose::moose::moose::moose: just for getting the valve gear together, let alone any thing else on the loco. :bow::bow::bow::bow::bow:

Thank you Gents.... it seems to take me an age!

And back to the Bagnall.....

I didn't want to use the cast valve wheels, which were just lumps, actually, and so a month ago I made up some etched one's I had onto NS wires, and put them so one side with the smokebox door in a bag.

I've now lost the bag.

I've managed to buy some more (different) valve wheel etched, and silver soldered them onto 0.5mm wire, and glued them onto the loco before I lose them, and also fitted the corresponding pipework.
I now have to make a new smokebox door, which is a pain. It's then over, apart from a bit more weathering a driver and some coal

Incredible work Mr Favell!

A pantograph is a great tool, isn't it?

And as to taking a long time, isn't that part of creating a masterpiece?

  What size end mill (cutter for the non machinists) did you use on the little parts? I used to soft solder the sheet that the parts were to be cut from, to a second sheet.That way the small buggers didn't fly off never to be seen again. When cutting was finished heat applied to the rear of the sacrificial sheet gave you the parts.

Thank you Herb!
I deeply love my little pantograph. I should love a real one - but I don't have the space- but meanwhile, this little bodge has revolutionised what i can do!

I've been using a 1.2mm diameter D bit, as being more resilient than the 0.8s, but still giving me good detail. These go through 0.028" nickel silver in a single pass.

So far I've simply used double sided tape to hold the sheet down. It means there's a slight burr at the end of the cut on small pieces (but not on larger ones), but it also
means I'm not cutting down into the steel below.

I certainly wouldn't have made the valve gear by hand.....

I.'ve used the double sided tape also, but for the sacrificial piece I have always used scrap  brass, just as long as it's flat. As I recall we would sand the face to remove any burr. Just so it looked like it had enough area. A 1.2 D bit is a challenge to grind, also, but as long as you keep it short, only as long as needed, they cut fine. Would grind angular ones also, in instances where a angular edge, or a chamfer, was needed.

The old daze. Now the Gorton seems to only see a nameplate, now and then.

Smokebox door sorted (Milliput) and glued on. It will now be destructive if I have to change the battery!

Weathering sort of done. Just couplings to make.
