Remove the stretcher etches from the fret and clean up. Choose the correct types
of stretcher depending on whether or not you wish to retain Bachmann's coupling
pocket.
Fold up the stretchers as shown. For the F004 type, make fold 1 first and run some
solder along it. Then start fold 3, bending to 45 degrees or so. Finally, working with
face B against a hard flat surface and holding face A, simultaneously close up fold 3
and make fold 2. If using the NEM pocket stretchers, make the four additional folds as
shown.
Solder the stretchers in place, locating their slots over the tabs in the ends of the
subframes.
When fixing the stretchers to the subframes, it's convenient to work with the
subframes inverted and the stretchers supported on heatproof blocks of some kind,
leaving both hands free for the soldering operation.
If you wish to fit the Alex Jackson coupler mounts, ensure the holes in the mounts
are opened out to about 0.3mm before fitting them to the stretchers at the outer
ends of the bogies as shown.
Undertray and End Plates
Remove the two undertray plates from the fret. Make the folds at each end of
each plate, to about 80° rather than a full right-angle.
Fit the plates into the subframes, noting that the lugs on the sides of the plates
engage in the recesses in the lower edges of the subframe, and solder the joints
between the two.
