the long road ahead - 67 Nautique resto/mod

What would you replace the exhaust boards with? I really don't feel like paying for a big chunk of fir for two little squares. Is this foolish or is it ok to use some pine or whatever I have laying around.
I do have a fir 1x6, is this going to give me enough material with a 3 inch hole through the middle of it? It doesn't seem like there would be too much stress here.

I believe the rudder port piece is 3/8" plywood.

Tim, wanna send me a couple small squares of coosa? ha ha.

Keegan,
Most home centers will have small 2'x2' sheets of exterior ply. I suggest it because ply will give you the support needed in both directions due to it's alternating grain in each layer.

Yes

Mike, by '88 all of that was 3/4...in my boat anyway.

I gotta throw this in for anyone in the neighborhood; Sweetwater has some sweet fir ply that is the nicest ply I've worked with short of cabinet grade. It has very few voids, it's sanded nicely, and it drinks the CPES!

Joe,    I measured the voids and they are roughly 6.75 x 8.75, I am figuring 3/4. I do have ply I can use, no big deal.

We got the stringers dry fit yesterday. After having the boat jacked up, and replacing the old stringers, there was a significant gap under the front half of the stringers. We compared new and old and they were about as exact as they could be. After going back and forth a couple times, we decided to drop the boat, and lift it slightly from the keel at about where the skeg is. This gave us a much better fit. There are still voids, but what I would expect now. We confirmed all of our measurements, and I like how they fit.
I got 3 coats of CPES on them. After the first coat I noticed we had failed to create drain channels, and to radius the tops of the primaries. Ooops.   Will do that tonight and get more CPES on those spots.
I have not drilled the hole for my cable block post yet, either, but as I had to move the one on the Mustang due to the newer style cable.

looking good! I am watching your progress. Just got my motor out today.

Looks great Mike. We'll be doing the same thing come spring on the Barracuda and will be using this as a guide. I'm really interested in how you are going to apply the different types of cloth and exactly what they are.

Mike/Pete, can you guys explain amine blush a little more? I've heard the term before and knew to wipe everything down if it cured but still a little lost as to what it actually is...

Mike's right on for the description. I don't know exactly what it is but it's like a by product of the cure. Some brands of epoxy don't do it so there must be a chemistry difference. It is water soluble so a solvet wipe won't cut it.

ammonium carbamate

It's made when CO2, the nitrogen compounds released by the resin, and atmospheric moisture react on the surface of your epoxy job.

We got the starboard main bedded last night. Filleted this morning. All three installed stringers are level, square and right where I want them. Have the port main filleted, and the port secondary's first two strips of glass down. I hope to get a good amount of glass on the mains tomorrow during the day, and install the last secondary tomorrow evening. Then just layer after layer after layer of glass. I need to coat the exhaust and rudder boards once more, and bed those in. Hopefully I can get to that tomorrow also. I am trying like mad to get the layup done before I head to St John. We'll see...
I swear I will get pics up as soon as my bro gets me all the ones he has taken.

I think I am going to run into this problem. PO replaced steering cable 3 years ago and he said it turns to one side sharper than on the other because of the new cable. He told me this after I had the thing apart already so I am not sure how significant the difference is. Ahhhh something new to research here on CCF.

Keegan,
To clarify what Mike has mentioned, the tube is adjustable in the block.

I am going to run out of epoxy.

I got several layers of tape on the mains and the newest secondary. I installed the risers for the gas tank also. Next I plan to install the exhaust and get some glass on those and the rudder plate. After that I will get the last couple layers of tape on the mains and start on the biax.
My stupid computer at home will not allow me to post pics for some reason, despite telling to allow scripted windows.

Mike's Pics.....Looking good man!
