The buffer beams were cut to the shape of the overlays using a mini drill and cutting disc. The overlays were then bolted to the buffer beams using the coupling fixing bolts. The outer ends of the overlays were glued to the buffer beams with silicone adhesive to prevent them from curving outwards. A fixing hole was drilled in each buffer beam to take the vacuum brake pipes.

The exhaust pipes were cut down and a Summerlands chuff pipe was fitted over the ends of these. 3/16" brass angle was cut to length and epoxied under the cab floor and front running plate to give the impression that the running plate extends for the length of the loco. This should look more convincing when the side tanks are back in place.
The regulator handle was removed from its spindle and after a bit of straightening, it was put back the other way round, with the lever at the back of the mounting bush. This was done to enable the dirver (a Brandbright 'Roger' minus pony tail) to fit in the very cramped cab.

The rivets holding the smokebox together were drilled out and replaced with 8BA bolts and nuts. The top front corners on the side tanks and the gaps between the smokebox sides and frontplate were filled with Milliput. Prepainted Roundhouse cylinder covers were clipped over the cylinders.

I had purchased some cast cab steps to replace the existing 'stirrups' but decided not to use them as they may prove to be a bit fragile. Instead I epoxied short lengths of 3/16" brass angle to the bottom of the 'stirrups' to represent steps.

The exposed brasswork including the top of the chuff pipe. boiler bands, chimney cap and gas valve in the cab were given a coat of self etch black primer.

I originally purchased the Roundhouse Millie with the intention of re-building the loco as a model of the original Tralee and Dingle No4 (the Hunslet with a cab at both ends). However although I am fairly competent at putting a brass kit together, my metal fabrication skills are not great. I have therefore put the building of T&D No.4 to one side at the moment and I have decided to make some cosmetic changes to Millie so that she looks more like something that might have run on an Irish roadside tramway.
This mainly involves fitting the Roundhouse cab and repainting the loco in black together with a few other additions.

Prior to the proposed modifications I had already fitted chopper couplings, a pressure gauge, boiler filling system and gauge glass and a natty 'brake handle' for the gas control valve.

The loco entered the works in late June but progress has been slow so far as there has been some good train running weather of late. I first removed the spectacle plate, cab rear and side tanks. The side tanks have been set aside for cleaning and painting. I cleaned the oil from the driving wheels and I have given these 2 coats of matt black paint. After that I fitted the Roundhouse crossheads and slide bars to the cylinders/connecting rods.

I purchased a pair of Roundhouse 'Billy' buffer overlays with rivet detail. I bought these rather than the Millie overlays as I intend to cut the buffer beams to the same profile as 'Billy' with a cutaway at either end of the beam. As the fixing holes do not line up with those of Mille, I am in the process of drilling new holes for the fixing screws and also for the 10BA bolts that hold the Accucraft chopper couplings in position. The ends of the overlays will also need to be cut as Billy is a lot wider than Millie.
