Measuring boom tube distance above flat bench.
Tub sleeves sanded flush with tub side.
Clamp the doublers in place
without
glue
and measure the ends of the tubes.
Both sides of the tubes should be the same
distance from the bench.
If not, loosen the clamps and adjust the
doublers until they are.
If the doublers or holes now have to be
sanded to fit, you must sand them and
repeat the measuring process.
This is a critical step in the assembly, and if
done incorrectly, your hull will never handle
properly.
When you are happy with the height of the
tubes above the bench, check to see that
the tubes are square front to back with the
boom square provided in the kit.
When you have checked and double
checked that the boom tubes are straight
and square to the world, remove the
clamps, but leave everything in place.
Mix up some 30 minute epoxy, and coat the
doublers where they will be in contact with
the tub sides and bottom.
Align the rails and clamp in place.
Quickly check your measurements and
square several times, and make any tiny
adjustments before the epoxy starts to cure.
Use any excess epoxy to build a small fillet
around the sleeves and doublers. Clamp in
place.
Set aside for at least 3 hours.
Repeat for the front boom tubes. Be sure
everything is perfect before you walk
away…
Once everything has cured, sand the brass
tub sleeves flush with the tub sides.
