screws, very lightly. If you understand the goal of these screws,
you won’t over tighten them. They are to hold the frame
halves and trucks together long enough for you to slip the shell
over the assembly. The shell is what eventually holds the loco
together. The plastic nuts won’t support a lot of tension before
they strip. Be gentle.
Alternatively, I’ll assemble the frame halves without the trucks
in place. The screws are started, but not tightened. Then the
frame halves can be split slightly and the trucks slid into place.
Finger pressure will hold the frame half together while you
tighten the screws very lightly. Remember to put a drop of oil
(21) on the frame halves before assembly.
7.0 Apply Kapton tape to top of frame
The Tsunami decoder selected for this installation is an un-insu-
lated board. So, to prevent fatal shorts either to components
on the board or our connections to the decoder, the entire
channel where the decoder will rest will be covered with a
layer of Kapton tape (22).
