I love this thread! I just got a 1967 Luger Leeward 16 from my neighbor, and I need to do some extensive repairs
. First one is stringer replacement:
The question is
- 1/2" Marine Plywood - 4' x 8' sheet - $75
- CPES: TotalBoat Penetrating Epoxy (1/2 gal) - $80 (coat the stringers with this)
- Epoxy Resin: TotalBoat 5:1 Epoxy Kit w/ Slow Hardener (1 gal) - $110
- Fiberglass Cloth: 6oz or 1708 Biaxial?
: which fiberglass
cloth should I get? 6oz or 1708 biaxial 45/45?
I've never done any fiberglass
work but I've read a lot so far. Seems Chopped Strand Mat (CSM) does not work well with epoxy. In choosing the fiberglass cloth, I also don't want to add unnecessary weight to the boat. This is a smallish 16' sailboat -- would ~3 layers 6oz fiberglass cloth be strong enough for the stringers
Some other questions
2 pieces of 1/2" marine plywood
bonded together for each stringer?
For fillets, do I need both silica thickener AND milled fibers to add to the epoxy resin in order to create a "peanut butter"?
Do I need to grind out the remaining old polyester resin at the base of the cockpit before laying new stringers using epoxy resin?
Stringer Pattern: I want to replace the stringers in a new pattern, the one Dave used where the stringers are at a ~45 degree angle instead of what was in this boat (attached photo) where stringers run parallel and perpendicular to the hull
creating boxes where water would gather. Is this ok to change the stringer pattern?
of the boat after removing old rotted stringers.
Here's some other photos of the Luger Leeward 16
