Its been a while guys but I've been slowly poking at my project...again, I'm redoing the stringers and all in my '85 Bayliner Capri cuddy cabin.
I'm trying to estimate how much fabric to order to recover the stringers. I'm going by the info I have at hand, the West System book.
MY ESTIMATE IS 1094 SQUARE YARDS FOR BOTH STRINGERS! Am I calculating this right?
Original encapsulation over stringers was about 3/16'' thick. 18 oz fabric is 0.0207'' thick (US Composites). I figure 8 layers. With a stringer estimated to be 3.75'' high and 3/4'' wide, and the West System book saying for the top/final layer to be about 2'' away from each side of the stringer, the first layer will be 12.25'' wide and 152.5'' long (148.5'' stringer with 2'' added on each end). Each layer should be 1/2'' shorter on each side...do the math for 8 layers beginning with the first layer, figuring out the square inch size for each layer. Add the 8 layers together and I need 19,698 square inches, which is 1,641.5 square feet, which is 547 square yards, and for both stringers, 1,094 square yards.
High school wasn't that far back but is this remotely right? At $7.60 a yard that's over $8k worth of FABRIC, not counted any chopped mat I need or stuff for the mounts, or the cross members, JUST STRINGERS.
Am I doing something waaaaay wrong or is this kind of work really this expensive? If it is I can probably find a Bayliner a couple years old for that much.
Thanks guys.
