3a. Butt joining plywood
are instances when butt joined plywood is acceptable solution such as
this tip of the Cirrus deck plate #3 about 2ft from the bow where there
is virtually no plate bending and the structural stress is insignificant.
The backing block
is made from the same material but I feathered it under the assumption
that it would be covered with fiberglass. Since the butt joint ended up
to be only 1/2" wide I removed (scraped out) the block immediately
prior to inside deck sanding and glassing. Had the seem been in a more
structurally sensitive area the block would be left in. Either way, the
block helped to hold the tip in place until all plates were solidly glassed
on the outside.
for transfer of plate template.
to keep the thin tips from breaking off prematurely:
- ALWAYS start the cutting from the tip into the plate.
- Hold the end so that it doesn't vibrate itself to disintegration.
- Never cut the plates all the way to the tips without precutting per
point # 1.
- Tape a piece of wood strip along the finished tip to protect it.
