Remove the two Upper Stiffener etches
from the fret and fit them into place.
Clean up the faces of one of the 2mm brass
nuts to remove any machine oil and grease
and prepare for soldering. Take one of the
full-depth 2mm washers from the fret and
thread it on to one of the 2mm screws.
Apply some grease to the washer and the
top few threads of the screw. From the
outside, pass the screw through the central
hole in the top of the bolster frame and
thread on the nut. Screw the nut into place
between the upper stiffeners and tighten
up. Check that the nut is central between the stiffeners and flat to the face of the
bolster top. Run generous fillets of solder around the nut and the Upper Stiffeners.
Remove the screw from the nut (it should have been prevented from being
soldered in place by the grease).
Remove the two bolster side etches
from the fret.
Fold up the traction ears as
shown. Note that Fold 3 is 180°
with the etched slot on the outside of
the fold. Make fold 1 first, then start
fold 3. Finally, gripping surface A with
pliers and supporting the main part of
the fret on a hard, flat surface, make
fold 2 and complete fold 3. Don't
apply any solder to these folds just
yet.
