Don't worry guys, I didn't kill myself after the stringer issues, I've just been radio silence for a bit here with a lot of stuff going on around the holiday.
Just a quick update: I finished grinding out what I could see fit on the stringers in terms of dry spots and bubbles. I also went around to any of the larger bubbles and drilled a small hole in them and shot resin in with a syringe, this actually worked really well. And then at some point, i just called it good enough. There are other spots I'm sure I didn't catch, but oh well...
Yesterday, I added back another layer of 8" wide tabbing followed by 12" wide tabbing, so, in total, I have anywhere between 2 and 4 layers of 1708 over my entire stringers depending on how deep I ground in certain areas.. In my opinion, I probably could have gone back over with 1 layer of 1708, but I wanted to be sure this thing was solid.. So now, even if my wood cores ever rot, it probably doesn't even matter lol.
I just have a little bit left to finish up on the one stringer with the 2nd layer of tabbing, as I was blowing through rollers every 10 minutes. I bought the foam ones to give them a try and they resin ate the glue that held them on their core.
All that being said, I think my mistake on the first layup was trying to do the stringers full length in one piece, it was just too hard to manage, and I couldn't get the back to wet out because I think I severely underestimated how much resin the mat on the backside eats up. When I redid this, I used 50" wide strips, overlapping, and I laid each piece out upside down on the hull and put a liberal amount of resin on the mat side first. This seemed to be the key as everything went much better this time.
Sorry, no pics right now, but you have all seen this stuff before lol
