When installing pad eye's in Balsa cored fiberglass, you must use the following
procedure.
1. Drill a hole the diameter of the through bolt you intend to use through only the
upper layer of the deck. If you drill all the way through, tape over inside hole.
2. Bend a sturdy nail over, so the short side from the right angle is about 1/4" /
6mm long.
3. Insert long end into a drill. Remove balsa core 1/4" from edge of existing
hole. Now you are ready to rig the Brake.
4. Mix some epoxy with high density filler. Epoxy should be consistency of heavy
cream. Pour into holes.
5. Redrill hole for fastener, and mount using an appropriate bedding compound
such as 3m 101.
Mounting Tips, Boom Attachment
Often it's possible to use an existing boom eye or bail for mounting the brake,
especially with the beckett style brake, where the brake normally attaches to
the vang attachment point. Also, many modern booms have sliding bails un-
der the boom. By removing the fasteners, a spare bail can be slide into posi-
tion and refastened. Otherwise, mount a through bolted, V shaped boom bail
in the appropriate position. Some booms will need reinforcing if light weight.
A rectangular plate riveted to the boom should be added to strengthen the
boom where the bail will be mounted, for boats planning extensive offshore
passages. Contact a qualified rigger. Try to isolate the SS parts from the
boom by using the supplied plastic bushings.
If the brake will be tensioned by a line running back from the mast, a V shaped Bail must be used (and the longer the
V, the better). You will also need another attachment point on the boom to turn the line back to the front of the mast.
Rigging the Brake
Brake Line Adjustable
Once the needed attachment points are
positioned, rigging the brake is simple. At-
tach the Brake to the boom bail. Note that
the brake shackle can be front or side
mounted. Wire the shackle pin to prevent it
from turning. Run the line from the deck at-
tachment point, through the Brake, and back
down to the turning block.
The line should then be run aft to the cock-
pit. Adjust the tension on the line with a 6
to 1 block and tackle or run the line through
a line stopper to a winch. If you use a 4 to
1 block and tackle, you may also need a
winch to get the line tight. You will be ad-
justing the tension on this line to secure the
boom, or allow it to jibe.
