METHODS OF CONTROLLING LOCATION AND

SIZE

If the tunnel area in the plug is correct, the boat bot-

tom mold should repeat and reproduce the tunnel

area which will aid the cut out process.

A reference area for the cut out can be produced on

the plug and bottom mold as a raised area or a cutting

guide.

Location pins (a) that would project into the internal

hull area could simplify the cut out process.

These location pin holes could allow the use of a 1-1/2

inch diameter hole saw to cut the four corner radii and

use of a reciprocating saw or router template to con-

nect the four holes.

CHECKING MOUNTING FLANGE THICKNESS

AND FLATNESS

Use a flat plate that will contact the flange at the refer-

ence points (b) and a .030 in. feeler gauge to check

flatness.

Additional sanding and / or resin / filler may be re-

quired to maintain the flatness specification.

A simple slotted go / no go gauge (c) will check the

flange thickness.
