the bottom of the frame (see A below). While holding, also mark along the front edge of the
frame with pencil or fine chalk line (see B below).
7. Disassemble the spacer bar and the unmounted frame. Use the bar as a straight edge and,
with one edge against the mounted frames tapered roller center and the other crossing the
dot you drew, draw a line crossing the dot (see “B” above). Set the bar aside.
8. Wrap the Mylar spacing guide around the pipe so that the left edge is against the trans-
ducer edge mark (see “C” above). Arrange so that one end overlaps the other by at least
three inches. Trim to fit if necessary, but in order to keep it square, be sure not to trim
at the overlapping end .
9. Realign left edge of the guide with the transducer edge mark. Line up both vertical edges
of the guide and ensuring that it is snug around the pipe, mark along the overlapping edge.
10. Remove Mylar spacing guide and lay it out on a flat surface. Either, measure the exact
distance halfway between the overlap edge and the mark at the overlap, or fold the guide
from the overlap edge to overlap mark and draw a line at the fold or halfway point (see
next page).
