Of course, I now expect to see the swaged pipe, lock nut and thread
QUE?
and the plate clamp half way down the down pipe.
Although one small query again (sorry Peter!) On the model you have a pipe running down from the top of the firebox down to the footplate. I'm just curious is this correct? I can't see this on the photo Mick posted. As an aside on the photo Mick posted the pipework looks to have been formed by a couple of first year apprentices - the pipework on the model has obviously been made by a time served fitter.
Adrian,
Sorry I don't understand what you are referring to. Are you suggesting there should be a pipe that follows the red line you have drawn? Please explain.
The "drain" pipe I have added is too short as explained by Mick. I now need to amend it so that it runs down to the running plate, and add the clamp. I'm wondering if there is also a clamp lower down behind "Mr Happy". I shall fix an extension pipe to the fire box and solder it to the back handrail pillar, cut the short length already in place back so that there is a butt join, and that will allow the ejector pipe to remain removable for painting.
Mick,
Now that you have shown that the pipe runs all the way down, I can now see it on many illustrations in various reference books. It's amazing what you can see when you know where to look! In Peter Tuffrey's book on A3s there is a photo of 1470 Great Northern on the turntable at Kings Cross. This clearly shows the pipe run and it is actually venting steam below the running plate.
By swaged pipe, lock nut and thread, I assume you mean the joint on the ejector pipe where it enters the cab? It looks like main pipe ends about 9 inches short of the cab and has a smaller diameter pipe welded to it, and this then joined to the one from the cab via a threaded joint and lock nut with grooves rather than being a hex nut. Something else to add.
I've got an MOK Std 4 tank calling to me!
What about the joint in the boiler cladding at the top? Looking at photos 60103 in preservation, it has a joint with closely spaced rivets (or possibly dome head screws). The Partworks, and DJH kits have these rivets as does the new RTR A3 from Lee Marsh. Looking through all my books, I cannot find any evidence of these rivets. I have found 2 photos in the Book of the A3s of different locos that show a joint line, maybe an overlapped joint, but no screws/rivets. There may be counter sunk screws but neither illustrations show them. My gut feeling is that Partworks/DJH and Lee Marsh are basing the rivets on Flying Scotsman in preservation and have go it wrong. Any ideas on that?
In the meantime I have scribed a line to represent the joint. It's not very deep and may not show when painted but the metal is reletivly thin so I dare not scribe too deeply. Thanks again for all the tips you've given so far.
Cheers,
Peter
