Notice that the pieces are coded with letters that will match up when you have them in the correct
alignment. The first two pieces to be joined are the
backstop
and the
base
.
Attach the alignment gage to the base using a 4-40 screw and nut as shown in the figure below.
Tighten the screw after you have placed the backstop against the gage and aligned it with the
registration marks. The alignment gage should be centered between both leaf holder registration
marks. The gage will stay in this position until the backstop and both leaf holders are soldered. You
only slightly tack a point on one intersecting pad and then check to see that it is square to the base,
aligned with the registration points, and flush with the sides.
If it is not, do not try the bend it to fix it,
you will lift the pad off the surface.
You need to re-heat the tack and straighten it while the heat is
applied. Once it is square, tack the opposite side pad. After a small tack is done on all the pads you can
go back and touch up all the solder pads, and it will stay square and flush with the edges.
