Tony,
It all looks quite mind boggling to me.
Hope it all works with not too many faults to resolve.
Dave.

Oh dear! Today has been one of disaster followed by partial recovery. I anticipated that the outside valve gear support frame/bracket would be very difficult to form into its rather complex shape. The first bends went OK but then, when I tried to form the required 1/8" radius 90 degree bends di...

Footplate overlays now fitted. Valance overlays next, then battle commences with the outside motion bracket. Looks like a pig to form to the correct shape. Overlays in place. You might notice that, in handling the assembly, I've managed to snap off two of the sand box filler plates. Hopefully, they ...

Not too much to show, but the cab has been fixed to the footplate and the splasher tops fitted (not in that order!). A couple of small splashers have been created to fit inside the cab front. These are necessary to cover the wheels after parts of the footplate and cab front have been cut away to cle...

Whilst pondering the need to move the centre splashers outwards to avoid the risk of shorting, I indicated that I would try the chassis out on the tightest curves on my layout. I've finally got round to doing this before fitting the splasher tops, thus enabling a visual check from above that the cen...

Thanks, Robin.
How's progress with Barrow Road?
Dave.

The main structure of the cab is now complete, ready to fit to the footplate once the splasher tops are fitted. The outer wrapper, various rain strips, roof ventilator and side beading have been added to the inner frame and the temporary stiffening plate removed from inside. Scot_086.JPG Scot_087.JP...

Looking a bit more like a re-built Royal Scot.

Dave.

Thanks for the helpful suggestions and comments. Regarding the required side play in the axles and splasher clearances, I have been following the discussions about frame spacing and had read Dave Bradwell's thoughts, but thanks Julian. Will, thanks for the reference to your gauge widening spread she...

The cab inner frame has been folded up and loosely placed on the footplate. Should be a fairly straight forward folding exercise but....The instructions warn to be careful not to distort local to the cab spectacle windows when folding the sides. This seems virtually impossible due to the lack of mat...

A start has been made on the footplate unit.It's necessary to have the basic unit made up in order to form the outside valvegear bracket folded to the correct width - it has to just fit inside the footplate valance. The photos show the chassis fitted to the chassis. The kit is a bit lacking in regar...

The basic cylinder structure and slide bars have been made up and temporarily fitted to the re-assembled chassis. Getting the cylinder frame to fit to the chassis has been a bit of a struggle. With the cylinder unit folded and soldered up, it definitely didn't want to fit into the slots in the frame...

Thanks, David.
Just looking at the last few images, I think I'm going to have to flood the "hoses" with a bit more solder. They look rather scruffy and uneven as they are. I hadn't really noticed on the model, but the enlarged images show them up.
Dave.

The remaining rear end pipes and hoses have now been made and fitted. Just the ash pan damper door levers to fit to complete the back end of the chassis. After battling the vacuum pipe into place and fixing, I realised that I'd forgotten to add the triangular flanges where the pipe joins the connect...

Mike. This Brassmasters kit is designed to have a removable keeper plate, which carries the dummy leaf springs and ash pan sides. The Black 5 and Jubilee kits I've built previously did not have a keeper plate arrangement and so, in the case of my locos, the driving wheels are fixed in the chassis. T...

Some of the pipes and hoses around the back end of the loco have started to appear. A couple more - vacuum brake and steam brake to tender, still to do.




Dave.

The pipe is now complete, with the final section added this morning. Although located in the end of the cast tail of the injector, it is not fixed there and is held in position by two mounting brackets. The final detail was the addition of the drain valve at the lowest point (or highest, when viewed...

The pipe has been extended rearwards, complete with wiggles and mounting brackets.

One last piece to do to join it to the injector.
Dave.

Slow but steady progress since the previous entry. The brake gear has been made up and a start made on he exhaust steam injector assembly. Although this latter is rightly considered to be cosmetic detail, and might be expected to be added later in the build, because the exhaust steam delivery pipe i...

Thanks, David, that's a super photo and most helpful.
Dave.

Yes, David is spot on; it's the LH side of the loco that's of interest. My concern was that the original routing of the exhaust steam supply pipe would interfere with the hopper ash pan doors. However, I've looked at the Pipe & Rod drawings for the Caprotti fitted Black 5's, which also had hoppe...

Jeremy,
Thanks for the photos. They don't really address my particular issue but all information is most welcome.
Dave.

Help and advice needed. The Wild Swan profile book includes the Pipe & Rod drawing for the rebuilt locos having the original style ash pan. That drawing carries a note that separate drawing shows modifications required for locos fitted with hopper ash pans. As a minimum, I can see that the large...

Here is the trailing wheel-set with the rather different profile balance weights on the two sides, as mentioned previously.
LH side.

RH side.

The crank pin screws have been reduced to length since the photos were taken. The nuts are 16BA opened out to 14BA.
Dave.

I think I'm entering a minefield! Driving wheel balance weights on Scots appears to be absolutely fraught, with lots of opportunities to get it wrong. The history of the various changes to the appearance of the balance weights is explained, in some detail, in the Wild Swan profile book but even so, ...
