the s/v stormsvala has been undergoing a complete restoration of frames (fastening sickness, heel rot), some of her floors(frame/floor iron sickness), and her fore keel and bow stem(maybe a collision and a bit of iron rot as well. i plan to replace the entire bow stem and the floors with white oak that i've purchased in abundance from duke at new england naval timbers. also i am going to replace all of her old iron fastenings throughout (including all plank fastenings) my questions are these:
1. i have the stock to make the stem out of one very large piece of oak (stem is 24' x 8") i have been advised that it may be better to laminate the stem in place using 1" laminates glued directly to the knee and gripe all the way into the fore keel. what is the better of the two applications, one solid oak stem or a laminated stem into the forekeel? i can remove the stem in one piece i believe so a pattern would most likely be available. i am working alone so take that into consideration.
2. the fastenings are old boat nails and woodscrews, some of differing material but mostly iron (the boat was built in 1938 and inproperly refastened over the years so there are alot of extra fastenings in her. she has some wood deterioration around some of the fastening holes but i will be able to go up a size on the fastenings. i have been advised that one way would be to use 1/4" lags with small washers to bring all of her frames to the backbone and also for the plank fastenings as well ( her frames are large 2 1/4 " x 3") so the frames can definately carry these small lags.
3. the type of fasteners is in question. she has had iron in her since birth which needs to be removed. i have priced out what a complete refastening of her planks would cost with each different fastener type and galvy seems to be the best for ny budget. i realize that in a perfect world i would go with bronze or sillybronze but the cost is extremely high. would galv. lags dipped in red lead be a good alternative for my aching wallet or would i be throwing my money away and have to refasten again in the near future or would the lags serve my purpose and enable me to use my savings on other parts of the boat?
some specifics: 50 loa, 40 lwl, 50,000 lbs, oak frame, fir planks, iron fastened, built in 1938 by nordjbaerg in copenhagen for alexander forbes.,
i am also looking for keel bolts as well (3' +/-) through an iron ballast keel.
thanks for the advice
