Module I
o Place mold halves together on rail, and gently rub back and
forth against the rail so they seat properly and make good
contact at the top. Make certain all sand dust is removed
from the rail.
o Put each mold half in its frame and place on rail so that
mold is centered over gap. Be sure that faces of both rails
can be seen from the top of the mold looking down
(Figure 20). Secure to rail by tightening mold clamp screws.
Mold should not extend below rail. Grind if necessary to
remove excess by using the mold base plate or a fiIe.
