{whilst this post is about GWR carriages I think that the ideas are useful for anyone building Slater's MR or SR coaches. If anybody is building Ian Kirk stock, please let me know if the ideas might work there}
My S7 layout - Scrufts Junction - needs some carriages for the miners and the day trippers so I have been working on some of Slater's GWR Dean four wheel stock. Glazing is to be slip glass as supplied by CPL and I have been fitting plastic strip to the interior of the sides so that the glazing can slide into place after painting. So that the retaining strips are at consistent spacing relative to the windows and to the cantrail I have made a few jigs to help in locating the strip... as here:-
The Slater's range of GWR four wheel stock covers all third, first / second composite, brake third and passenger brake van and those models require four jigs to cover all of the different window patterns. If you like the Slater's GWR Clerestory coaches then the jigs for the 4-wheel kits fit the sides of the bogie kits. Here is what the business side looks like:-
Jig for a toilet window to the left and for a quarterlight / droplight / quarterlight to the right. The jigs are made from 40thou plastikard sheet with a fence to align the jig against the top of the side. The black plastic piece fits into a window space... corners are cut at 45 degrees to minimise the work required in getting the piece to fit into the window space - the piece is required to fit only the side and the top /bottom of the window space and thereby align the left / right edges of the jig relative to the windows. The black piece has a hole in the centre so as to be able to drop some solvent into place without sticking the black styrene to the coach moulding. Here is a compartment jig in place:-
To my surprise the quarterlight dimensions are constant for first / third class compartments and the separation of the quarterlights within a compartment is constant... the photo above shows the jig in a 3rd class compartment and the photo below shows the same jig in a 1st class compartment:-
And this is the rear of a side... draw around the jig to show where to stick the glazing bars:-
With the lines showing where to fix the 10 x 40 thou (spacer) and 10 x 80 thou (retainer), this is the result:-
Things are not quite as easy as implied here... the sides are moulded and hence there is some (variable) flash around the inner edges of the quarterlights and droplights, that flash prevents the jigs from fitting smoothly. I have made a window gauge so that I can sand the openings, to remove the flash, to a consistent size:-
One black tab gives the height, and the other black tab gives the width, of the light - this gauge is for quarterlights and toilet lights, another gauge does the droplights for the compartment, the luggage area and the guard's door.
Anyone know of a source of 7mm window cleaners?
