focus of the restoration to date is on the frames. The main frames are
supported by a very simple sub-assembly (formed of two channels) which
carries the springs & axleboxes. When 4415 was re-gauged from 2’ to
3’ to run on the Castleberg & Victoria Bridge Tramway these
channels where simply moved out. In the photos of the upturned chassis
by Ron Walker on 14/8/15 the witness marks of where the channel sit for
the 2’ gauge option can be seen, with further holes outside for the
re-gauging. Why there is a third sit of over-lapping holes we have yet
to fathom out! Hopefully this all makes sense when you see the Kerr
Stuart picture of the sub-assembly below.
The photos below are of the main frame (which is carried by the sub-assembly)
some point in the past the frames on the drivers’ side have been
subject to a rather horrible repair. The bolted in patch ( also
in photo below) is connected to the rear buffer beam by the 3 very long
is a view of the same repair from ‘inside’ the frames (drivers side,
looking backwards). The clevis (centre) is the anchor for the axlebox
tensioners (which Kerr Stuart describe as ‘radius rods’). The clevis is
contained in a slot to allow the frames to be re-gauged. The channel
which carries the springs and axlebox assemblies sits on the square
hole above the clevis.
|Above is the same view after removal of the repair, and with the frames cut back to receive a repair piece (to be welded in)
frame repair, prepped & ready to go. Original clevis re-used, but
the rest is new. It does say ‘this way up at the bottom’. Rick does
know what he is doing; the frames are upside down at the moment!
of the radius rods were missing. Will High took the KS drawings and
re-drew them in CAD format. Lazer Centre UK them manufactured them from
Will's drawings, complete with 1 ½” Whitworth LH thread. The shiny
components are new, the others original. The longer set fit between the
centre and rear axles (as can be seen in the KS photograph).
