Thats great. If you already know how to tie every knot and splice you will
still get a kick out of this site.

Weldwood contact cement for laminating
scarf's & ply's of mast. Any Comments?
Contact cements are pretty tricky to use correctly. If what is spoke of here
is what I call contact cements. You must apply them with the parts separate
and let it dry to a certain point then join the two parts. When the cement is
in this stage you can not let the two parts touch at any point or they are
cemented together, if not forever for a long time. The normal use of contact
cements are for things like putting a sheet of laminate sink top onto a
substrate of wood. There you put the cement on both surfaces, allow it to dry to the
touch. then put down wax paper or release paper on the counter, lay the
topping in place and pull out the release paper. Then pound on the covering to
make sure all parts have been in contact. Since it is used in kitchen sinks I
presume it is water resistant, but would be a tricky proposition to laminate a
mast with 20 feet of wax paper to pull out without disturbing the alignment
of the parts. Epoxy with slow hardener does give you some work time before
you have to clamp and leave. Contact cements would eliminate that wait time
(two or three days, when using slow hardener) it takes for epoxy to really cure
before putting stress on the joint.
