Yeah we decided to forego the knees. Our thought was that it's already 100x stronger than the rotted wood we took out, and after we glass the rear cap back on and tab the floor into it we should be good. If we had gone with a full transom with a bracket I would have, but this is staying at 25" and will only have a 115 so it should be plenty strong

Sounds like a plan  :nSalute:

Had to do a little surgery on the starboard stringer before getting too much further. Good news is the foam is dry. Bad news was the tank was not secured properly and it was rubbing on the hull which caused the stringer to delaminate some.

Started out by cleaning it up with the grinder and chasing the crack as far back as needed.



Then went back and added a few layers of 1700 to bring the hull bottom back up flush with the rest.



Finally the remaining gap was filled with bonding putty and the entire stringer was glassed back down with three layers of 1708 with 4, 6 and 8 inch overlaps.



We were trying not to walk around in the hull too much to prevent it from separating more so now that it is secure we can focus on the stringer tops and then start on the floor.

Yeah, the tabbing they used was just woven roving.  The 90 degree orientation of fibers after means little strength where it is needed most.  Biax 1708 or similar will result in a much stronger tab.  Great news that the foam is dry.  That will save money and time.

Yes, saving time and money is always good! Now the center stringer can be addressed before prepping for the tank to go back down.

Nothing really photo worthy but we're still picking away. Got the stringers fixed up and raised using the same method as my boat. Added some more glass to the hull bottom since there was so much sanding and started templating up the bulkheads. Also got a new fuel tank and finalized the layout for everything. Should be moving quicker here soon.

Hey everyone  its been a  little while. I am working with Nidacore I glassed the top and bottom of panel and was wondering  what techniques do you use in filling the edges of the nidacore? Feel free to explain the concept and reason why its important. Im sure its obvious but I just need a solid answer.
Thanks
Thanks

What are you using the Nidacore for?

I used a similar composite for my decking/sole and had to figure out how to work with it.  Here is the portion of my rebuild where I was working the deck.

Hey Rick. We're using it for the sole but here's the current dilemma. For some reason the aft six foot or so of the stringers are an inch lower than the front. There's a dip right behind the old wiring trough. We used blocks of pvc to raise them up but need to level out the back. We were thinking a strip of 3/4" nidacore with two layers of glass on each side and a little putty should do the trick, but that got us thinking about the edges. Is it worth filling the edges of something that won't ever see the light of day again? In the grand scheme of things it's not a lot of effort or money so we will probably just do it, but we're curious what the consensus here is.

The core is plastic so it should be fine BUT I am not sure if it sat in water what would happen. I think I would put a small square of it in a bucket of water and see if it affects the glass any. Maybe weigh it down and leave it for a week?

Still plucking away at it. We got the stringer dilemma figured out with a coosa board shim. Not sure if all these 80s model 200s had the same stringer setup, or if this was just a Friday boat but man it was off. My 22-2 was straight all the way back. Oh well, it's straight now and ready for the floor.



We also decided on a big floor hatch for the front and one for each side so some bulkheads were in order. Went ahead a made a new tank coffin while we were at it to keep it off the hull bottom. It took a while given the limited time he has to work on it but it will be nice when it's done.

Next big checkmark done! We finally got a free weekend day off together and got the floor down. It's nice to finally have it coming together. I'm going to keep on Nate to get this thing done and hopefully have it back on the water this summer.

Tank secured, hoses double clamped and double checked, storage boxes and bilge gelcoated and ready to go.



Floor down. We used about a gallon and a half of bonding putty from FGCI to make sure it was stuck good and then went around the edges with some fiber reinforced filler to help lock it all in place. Now that it is dried Nate can add some tabbing and fair out a few small spots on the seams

Nice going!  Looks like it’ll be easy fairing. Sure hope you wrote down some good measurements where all that subfloor stuff and hatches comes thru!   ;-)
