And now for double the trouble. Hinges and bolts as promised:
After bending some brass wire with round nosed pliers into U shapes about 1mm wide and with tails 4mm long, I then marked the centres of each hinge on the inward opening side of the door.
Now the important bit; Cut two slots a half millimetre either side of the marks at 45 degrees, then carefully slice out the edge between to create a little flat chamfer. This will not only be an aid for drilling, but will serve to bring the pivot point in as close to the door edge as possible.
Drill two holes right through the door, again at 45 degrees, then fit and glue the loops, using the exposed tails on the outside for fine adjustment and ensuring a strong bond. When set, these tails were filed flush.
I then formed split pins, this time using thinner wire. With the door held closed in it's frame, drilled through the loops, right through the frame and at 45 degrees (90 degrees to door hinge). Once again, the tails permit the last and most critical fine adjustment. I also applied glue to these ends, allowing it to capillary inwards to avoid gumming up the works!
When everything had been set up, checked and thoroughly tested, glue applied and set, one or two of the ruddy thing refused to work properly. Always happens doesn't it? The finer wire was more easily tweezered, twiddled and twisted into submission!
I made the bolts simplified without fine detail as they have to be strong, yet easy to work using crooked digit and fingernail!
There's rather too much daylight showing under the draughty old doors, but they were only temporarily masking taped in for the photography!
And for my next excuse; I didn't bother about those two naughty little gaps on the left hand door. They will be covered by a nice SR "Please show tickets" enamel sign!
I have since been given the opportunity to try the method scaled down on a 7mm building, and found to my surprise that it was no more fiddly or time consuming, and worked just as well too!
No excuse for boring old, glued solid, pretend doors now! I can't resist it. Even the tiniest doors just have to be slammed!
