Airfix Mineral Wagons - part 1
Bill Bedford 16T Mineral Airfix EM
The first job has been to replace the floors with a piece of .040" plasticard 29.5 x 63mm, partly because the original floors are undersize and partly to save me the effort of cutting away the moulded ribs. Axle positions and centre lines were scribed on the floor before the body sides were glued in place;
Then I could use these lines to position the w-irons, helped by a Brassmasters jig;
The non-door end bufferbeams have been glued in place, after drilling for MJT buffers, and I've started adding weight;
On its wheels, note that the hinges have been cut away;
The Bill Bedford units were built up and the bends strengthened with a light fillet of solder, although I'm not sure if soldering is necessary. Kean-Maygib waisted bearings are being used. I've had to bend the w-irons in further to take out a lot of slop - the axles had up to 1mm of sideplay. Down to bearing choice perhaps? I'm using the supplied .012" wire - anyone know what are the recommended weights for .010" and .012" wire sizes?
The next job is cutting/filing the w-irons off the solebars.
