I've continued with the various outstanding jobs whilst waiting for the final design of parts to be returned from the etchers. The artwork was sent off on Wednesday, so the parts should be in my possession at some point next week.
In the same manner as Chris Pendleton with his 4mm Deltic, I've used the springs on the JLTRT sideframes as the studs for mounting the parts for the primary springs. Here the modified sideframes can be seen:
The mounts need a certain amount of cleaning up, but this can be done quite easily with the judicious use of files.
The frames have all been cut to the same depth and diameter using a home made cutter, again shamelessly cribbed from the MRJ article. It's made from a length of 3/16 inch silver steel, drilled 3.3mm. The brass stud is turned to 3.3mm OD, with a 1.5mm tail, to fit into a 1.5mm hole drilled into the centre of each spring moulding.
I also made the revised axles, again from 3/16 silver steel. They are each 45mm, turned to 75 degrees at the end, which will hopefully assist with centering them when the wheels are pressed on.
The sideframes have been cleaned up where the moulded axleboxes have been sawn out and I've also removed the moulded securing hooks and lifting lugs - these will be replaced with etched parts, which are included on the bogie frets.
Work this afternoon will concentrate on making up the rest of the traction motor units, and getting everything ready for the mark 3 bogie parts. The equalising beams need to be cut in half, and then filed down to fit in the stirrups, which will be soldered to the axleboxes.
