Back here again after a long absence.
I had spent so much time on the layout during 2018 and it had become a teeth-gritting operation to get it in a reasonable state for the exhibition. So I was quite glad to get it back from the exhibition, set it up in its home location in my bedroom, and forget about it.
Well I couldn't really forget it since I saw it night and morning.
I had been concentrating on 3D printing and the 1:32 scale loco but that had come to a halt awaiting delivery of an ABC gearbox. However, I did a bit of business with a fellow S scale modeller to obtain a tank car for the switching layout to serve one of the industries and that re-fired enthusiasm to re-start on the completion of all the buildings and to fit their doors, windows, etc.
So I started on the building at the extreme right of the layout - the one based on the Glazier works from the Shorpy pictures. I started on the windows and developed another method of doing it based on what I had described last year.
US Style Track in S - Jameston & Leven River RR
I was getting close to actually modelling a sash window frame that I decided to actually do it.
I started off with the window frames which were cut from card in the laser cutter.
The two parts were glued together as before, around the edges of the frames, then the glazing bars were stuck together with a scoosh of Halford's grey primer.
The ones on the left are for the slightly larger lower windows - the ones on the right for the upper windows.
I then started constructing the main frame for the sash
I started with the side member from 3mm x 10thou strip and the front bead from 30thou x 10thou strip glued to it.
The outer channel for the upper frame was then contructed from 10thou x 40thou strip with the centre bead from 10thou x 20thou strip.
The inner channel was next added also using 10thou x 40thou and 10thou x 20thou.
I constructed a base for the assembly using 80thou styrene - the "U" shaped piece on the left. This was cut on the CNC machine to give me nice square edges. I do not like cutting thick styrene sheet and truin up the edges so I let the KX1 take the strain.
The part on the right is the sill from 5mm x 20thou strip.
The sill is fitted...
...then the two side parts of the sash frame are fitted.
The two window frames are cut from their surround...
...and are fitted in the appropriate channels of the sash frame. At this stage they hadn't been glued in place hence the top one being slightly out of line.
From the rear, the glazing is slid into the channels behind the window frames. I am using 0.5mm PETG and the thickness of the window frame with the coat of primer is just under 20thou, so the sash channel width of 40thou gives a mild push fit for the glazing behind the frame.
The window from the front with the glazing in place. The sash frame has also been completed with a 3mm wide strip across the top to represent the filling under the arch in the brickwork.
And the window in place in the building as a push fit at the moment. The window will have its glazing removed when it's being painted, then put back together and fitted in the building with a small touch of glue.
I quite like this method since I can quite easily set the window in any variation of opening. Another small plus is that you can see the inner sash channel behind the upper window frame, which is quite a noticeable feature on the real thing. Only another nine windows to make for this part of the building.
