Re: Brimsdown-The last grand project.

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

Re: Brassmasters Rebuilt Royal Scot, 46109

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...

Re: Brassmasters Rebuilt Royal Scot, 46109

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 ...

Re: Brassmasters Rebuilt Royal Scot, 46109

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...

Re: Brassmasters Rebuilt Royal Scot, 46109

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...

Re: Brassmasters Rebuilt Royal Scot, 46109

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...

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...

Re: Brassmasters Rebuilt Royal Scot, 46109

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...

Re: Brassmasters Rebuilt Royal Scot, 46109

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...

Re: Brassmasters Rebuilt Royal Scot, 46109

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...

Re: Brassmasters Rebuilt Royal Scot, 46109

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.

Re: Brassmasters Rebuilt Royal Scot, 46109

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...

Re: Brassmasters Rebuilt Royal Scot, 46109

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...

Re: Brassmasters Rebuilt Royal Scot, 46109

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.

Re: Brassmasters Rebuilt Royal Scot, 46109

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...

Re: Brassmasters Rebuilt Royal Scot, 46109

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...

Re: Brassmasters Rebuilt Royal Scot, 46109

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...

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.

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, ...
