Re: fiberglass relic restoration
The original stringers were only 3/4 wide.
I thought i would laminate 3/8 to fab stringers. that yields a greater lap...4 feet, which should be stronger than a 6" lap using 3/4. 2x 3/4 is just too wide for this little boat.
The deck was 1/4 in aft 2/3 of boat and 3/4 in Front third (4 inch step) so I also plan to use it for the deck in aft section. I'd rather use 1/4 for deck because of weight distribution, but i can't find 1/4 acx. closest i came was the 3/8 "marinetech" ab fir. The additional weight will make it aft heavy (not by much...10lbs tops),
I fish flats, never go into the gulf, rarely see 2' waves. usually out on a light chop or at night on black glass. i'd like to make it bulletproof but honestly i just want to milk ten years out of it.
while i'm being honest, i calculated the fabric and resin needed and have decided to use 1 1/2 oz csm for nearly all of the lam and layup. there was no biax in it. think it was made before it existed.
I plan to use 1708 only to re-tab and recover the transom, twice. 1st time lapping the port side, second time lapping the starboard, both layers over the new tabbing...bulletproof
Considering the original stringers were finger-jointed 3/4 stock (like cheap paint grade baseboard) and tabbed in with csm, i believe 3/8 stock laminated togther with 1 1/2 oz csm will exceed the strength of the originals. after the stringers are tabbed in, i plan to coat the inside of the hull (below the floorline) with resin and add a new layer of csm, going over the stringer tabbing. this will actually be double-tabbing the stringers, sealing and strengthening the hull. the deck will also get tabbed in twice, 4in then 8in over top...all with 1 1/2 csm.
Of course this is only my plan
objections will be strongly considered :redface:. My approach will keep my budget within reason...125$ in mat, 125$ in resin, 80$ plywood, plus the cabosil, the finish coat on the new floor, a lower unit oil change, couple of ss heli-coils, new float switch for bilge pump, bunk boards for trailer, etc.
aint the way i want to go but i cant put 1000$ into an 800$ boat. now you know the plan, hope to hear i'm not wasting time money and effort. i'f i must, i'll 1708 the deck, over a layer of 1 1/2 oz csm. adds another 56$. planned on $300...turned into $500. maybe i shoulda parted it out :facepalm:
