There is no reason why the buffer layers should not be made part
of the foot plate and soldered to the ends of the footplate using
the rear and front foot plates and the valences as a guide, which
may make fitting body and chassis together a little easier. If this
is done the tabs on the ends of the frames should be carefully
filed flat since they will no longer have a purpose.
The rear buffer has two layers. Drill holes 0.45 mm in Rear Buffer
Beam (5), Rear Buffer Beam Overlay (6) and Rear Buffer Housing
Plates (38,39). Drill large holes in Rear Buffer Beam Overlay (6)
and Rear Buffer Housing Plates (38,39) to 2.0 mm which will
locate the un-sprung rear buffers.
The Rear Buffer Beam (5) has four slots for the frames, the outer
pair of each pair is for P4 and the inner pair is for EM. The outer
pairs are for the secondary (external) frame.
Remove
Rear Buffer Beam (5)
from the fret and solder over the
end of the frames ensuring it is the right way up, the two slots
are nearer the bottom.
Remove
Rear Buffer Beam Overlay (4)
from the fret and solder
half etched Rear Buffer Beam Overlay (6) in place again ensuring
it is the right way up. The holes and slot are nearer the top.
Remove
Rear Buffer Housing Plates (36,37)
from the fret and
solder into place. Ream out the central holes and fit the Cast or
turned Rear Buffers.
Remove
Rear Buffer Beam Draw Bar Plate (41)
from the fret and
solder it in place to match the draw plate slot.
Fit
Drwg. 216 Rear Buffers
in place and solder.
Secondary Frame
Push out the rivets if required in Rear Frames (236,237) and
remove them from the fret.
Bend so that the half etch is on the inside and insert into the
sides of the frame and one of the outer pair of slots in the rear
buffer depending on whether you are modelling in P4 (outer) or
EM (inner).
Buffers Beams - front
Note
The Buffer Mounts (32,33) are optional. When first built they
were not fitted but were added later. The rear part of the Gibson
buffers (small circle with a hole in the centre) may be mounted
behind the buffer beam, in which case a small notch needs to be
filed to accommodate it. The four small holes in the corner may
be used to locate the buffer mounts and again optionally, the
Gibson buffers may be drilled out in each corner to 0.45 mm so
that the fixing bolts may be simulated.
The front buffer has two layers. To simulate the bolts that hold
the buffers to the buffer beam drill the locating holes in Front
Buffer Beam (3), Front Buffer Beam Overlay (4) and Buffer
Mounts (34,35) to 0.45 mm.
Remove

Buffer Support Right (25) and Buffer
Mounts (32,33)
from the etch.
