Quote from: Hailstone on Today at 01:15:37 PMSorry John, but that is the smokebox tube plate the large hole is indeed from the dome, but will lead to a spliiter casting to from which the main steam pipes will lead down to the cylinder block. the nine holes just below it are where the longitudinal stays go. the ring of holes around the edge are where it will be riveted to the boiler and the outer set of holes will attach it to the smokebox. the detritus covering part of the plate has obscured some of the rivet holes.

Also, what John called the firebox front plate is more commonly called the throatplate.
You can see on the upper pic how it's rolled back at the sides to join to the firebox outer wrapper plates and forward to form a "shelf" which locates the underside of the boiler.

Occasional Special No. 3. Part C


Hello Chums

In my previous postington, I mentioned the frontplate of the outer firebox seen in the picturingham had been removed. I thought it might be useful to see a boiler with the frontplate in place:-





You can see the heads of the stays securing the outer firebox's frontplate to the inner firebox. We saw the holes for these stays in the lower part of the inner firebox in the previous postington.

This picturingham also shows, as far as my coarse photography permits, the rivets for the foundation ring - lots 'N' lots of them, closely spaced. Running in a vertical direction at the front corner are the rivets holding the frontplate of the outer firebox to the wrapper plate [the 'side plate', if you like].

Right-o, lets have a butcher's hook at the part of the frontplate we cannot see in the picturingham:-





Sorry about the gravel! This is the frontplate of the outer firebox, with its bottom part cut off. This is rivetted to the boiler shell and the outer firebox's wrapper plate as mentioned ante - the smallest diameter holes, arranged in circular patterns, are for the rivets. The big hole is for the regulator rod, passing from the regulator handle on the faceplate to the regulator valve in the dome.

You can see the holes for the tubes - the top row of nine matches the top row in the inner firebox, seen in a previous picturingham. This is the boiler from a saturated engine, if it was fitted with a superheater there would also be larger diameter holes for the flues.

Hopefully the picturinghams give you an idea of how the inner firebox fits inside the outer firebox.

Next, we'll have think about stays. No tittering at the back, please. Not the stays on a lovely lady's corset - the stays stopping the inner firebox from bulging out all over the place. Come to think of it their jobs are similar.

To be continued...

Many thanks for looking and all best wishes.

Sorry John, but that is the smokebox tube plate the large hole is indeed from the dome, but will lead to a spliiter casting to from which the main steam pipes will lead down to the cylinder block. the nine holes just below it are where the longitudinal stays go. the ring of holes around the edge are where it will be riveted to the boiler and the outer set of holes will attach it to the smokebox. the detritus covering part of the plate has obscured some of the rivet holes.

Quote from: Bealman on Today at 10:01:22 AMWhen I first glanced at that second picture, it reminded me of the toilet on the second floor of the three story terraced house in Stockton-on-Tees I lived in back in 1972....

Nuff said!!!

Then I shall be forever grateful that I didn't find myself on the first floor of said dwelling hoose in SuperbStockton!

All the best, George.

Early 80s designs in the 1/160 range would be much appreciated! 

Not on your list but the CAI Red and Cosco blue high cubes from your 1/160 range would be good additions as see them a lot on modern trains

HC do not appeal to me as they did not exist in the 80s/90s. MSC sand has already been done. Something different would be ideal.

OCL blue
Nedlloyd grey
GOLD brown
Cti red
BEN grey
ACT white
Matson red
Triton brown
Original Suttons would be nice too.

You can say that about most of us! Glad the chassis fitted!

In my defence, it was on offer and you can't have too many NDVs/BGs if you're modelling a parcels terminal...
