My first restoration (1958 Glasspar) and my first post, so go easy on me. Read many other posts, but there's nothing like getting direct input on the project in question...like having a bunch of smart uncles to call on.
To my surprise the stringers are in pretty good shape. All were only partially covered by fiberglass. The center stringer is only four feet long and will be replaced. The other stringers need a little help near the stern, but at over 50 years old, that is to be expected. Actually, I expected them to be much worse. They are still sturdy and dry, but the tops where they were not glassed over are munged (but the lower 3/4+ are solid), so I am planning to do the following.
1. grind off the existing glass to ensure sister pieces will join nicely
2. measure and cut the sister pieces, using 1-by oak: 4 - two footers and 4 four footers, one on each side of the existing stringers
3. coat the sister pieces with resin, especially the ends, and let dry
4. cut off the munged tops and spray with bleach/water mix to fight back any dry rot
5. glue (3M 5200) and screw sister 1-bys to the existing stringers
6. glue and screw the three cross pieces (frames), also using oak, since each is only 29 inches long and 2 inches wide
7. glass (csm and poly resin) over the unglassed portions
Is this a reasonable plan? What steps am I missing? Should I use PL to bed the sister pieces?
