Bachmann 'Peak': Cosmetic Bogie
Frames and More Rolling Tests
This section deals with fitting the moulded plastic bogie frames to the etched brass
Bolsters. Buffer height checks and on-track towed or pushed testing can then be
done. Illustrations are of both Peak and Class 40 models: some details differ but principles
are the same.
The sideframes are fitted to the Bolsters because the real locos do not have secondary
suspension. It is therefore correct for the sideframes to swivel about the pivots without
any 'pitch' or 'yaw' with respect to the body. This means that you do not have to
artificially increase the gap between sideframe and body, and that you can fully detail the
items in the space between the two.
Take
the
Bolster
and
the
moulded
sideframe/undertray moulding for one of the
bogies. Offer the moulding up to the Bolster,
engaging the two central pairs of outriggers in
the slots in the etch. Mark the plastic
outriggers for cutting, flush with the inside
faces of the Bolster's legs.
Cut through the two central pairs of plastic
outriggers at the marks. Cut through the
outer outriggers closer to the inside faces of
the sideframes. Leave the inner cross member
in place for now.
Cut through the two vertical square pillars
joining the inner cross member to the
undertray, thus separating the undertray from
the rest of the moulding. Discard the
undertray.
Clean up any flash, lumps or bumps from
the inside of the sideframes.
Remove the tension lock coupling from the
NEM socket: squeeze its tails together and
pull it from the socket. Reduce the projection
of the NEM socket to no more than 2mm from the inside face of the buffer beam, or
remove it altogether.
