Rebuild Repower

Trying to get it right the first time I spent a few days measuring and re-measuring. I think I got everything where I want/need it so I cut the stringers.
They Came out good just need to fine tune them. The joint I decided I suck a scarf joints so I used what I call a saw tooth joint (not the right name). I decided to make the interlocking teeth 8in then glue them with peanut butter. The process wasn’t the bad just I was over measuring everything so I didn’t waste and plywood.

Hoping to have time this weekend to mock fit the stringers, bulkheads, and outside wedge pieces. Once I get things close I have to wait until the 16th to glass them in. I only have 1 or 2 gallons of resin left I know that’s enough for at least one side, but I really want to wait until I get another 5 gallons.

I’m planning on getting each stringer 100% glassed in one sitting to get a chemical bond throughout the whole stringer to boat connection.

Nice work!

Twist - I was wondering, in shaping your stringers are you matching the bare fiberglass height of the original? Reason I ask is there was 1" of peanut butter bridging the gap between my stringer tops and the sole. I've read many folks on iBoats and THT use PL Premium to secure the sole but I don't think I'm going to make up 1" of gap with a polyurethane adhesive. My thought is to increase my stringers by about 3/4" so there isn't as much gap to cover.

with your joints in the stringers...

There's no reason not to also sister a length of plywood across the joint and glass them together.

I’m doing a mix of what you talked about. I went through took all the measurements and then transferred that to the sides of the hull. Used a y foot level to confirm the heights. This created a floor height level. I then ran strings at the sights of the bulk heads and stringers to get the heights. Thankfully the heights were all very close 1/4 inch off. Used a common middle height, that put me close.

Skunk, I was thinking the same thing.

Did you get any glassing done on your stringers this weekend?

[Slightly_Twisted]

Wow it’s taken so long to get things moving. LOTs of little adjustments to get the stringers to sit just right and give me the height I wanted. Took a few days to grind the surrounding glass to get a good bond once I start glassing.

Work has got me putting in way to much time and passing off projects that they “can’t find the money for, but can find the materials”. I work with a high school athletic teams and I built a few chillers for drinking water years ago. Well they wanted another and one three times the size. That’s taken a lot of boat time away!!

Got the stringers “glued” with thickened resin and fiberglass dust today. Forgot to get pics of the alignment cribbing, but here is after they sat for 8 hours.

Looking good. I hope to be at that stage after Labor Day Weekend. I will confess being a single guy with no real commitments outside of the daily grind helps with my rate of progress, though my wallet needs a little recovery time just like my body does LOL. I like your shelf/table over the gunnel. Might have to replicate that when I'm glassing in my stringers.

Well took me a week but I was able to slowly chip away at the fillets. I got them all rounded and sanded on the inside. I’m waiting for a 1/2 hand held belt sander to get the out side done. I was going to get the cheap harbor freight one but went with the amazon one for the free shipping. I get it tomorrow. Sunday I had the morning to myself so I spent 4 hours tabbing in the inside of the stringers. I wanted the best bond to the transom so I but a layer covering the middle 1/3 of the transom. Then tabbed in the stringers and knees with three layers of 1708 tape. 8inch, 10 inch, 16 inch. All wet on wet. had a few hiccups but over all other then my back be sore it came out nice. Only Took one pic, had to take a break and stretch out a little.

They are far from done I need to put a waterproofing layer from the tabbing up and then a cap. I’ll use 1708 from the tabbing to the top and then I have some 6oz cloth for the top waterproofing layer.
