Mike's 77 22-2 Rebuild

[Tampa Bay Mike]

I follow you. I am planning to make some sort of cabinet back there but I'm not going to use the knees as bulkheads mainly because of how much coosa it would use. ($$) I am able to cut these out of the side of the same piece I used for the transom and still have the entire bottom left for whatever else. I sat back there for a while trying to figure out a good way to tie them into that angle and my dad took one look at it and said "just cut off the side of the stringer". Seemed like a much better and easier way to go.

Got the top of the transom smoothed off some and tacked the knees in with thickened epoxy. Also glued in some PVC drain pipes. Next I'll build up the back stringer shell with about 5 or 6 layers of 1708 and then tab everything in with at least 3 layers all around.

Looks great.

[Tampa Bay Mike]

Got the braces off and tabbed them in with 3 layers of 1708 and stuck a few layers down on the stringers.



Next I'll add the foam and then a few more layers over the top to seal them up.

Ran into my first "oh " moment of the build tonight. When I glassed in the drain pipe through the stringer, I didn't think to glass in the entire length of the pipe, I just did the ends where it came through. Well of course this meant that any water going in could leak out inside of the stringer into the foam. It also meant that any 2 part foam poured into the top of the stringer could leak into the pipe and drain out all over the bilge area!

After a lot of cursing and plugging the drain hole with my finger to keep it clear, (yes that stuff gets hot!) I was able to scrape most of it up before it fully cured. So now I get to rethink my limber holes. In hindsite, I'm actually glad it happened now so I didn't end up with a bunch of soaked foam down the road. I hope you all get a good chuckle out of this and hopefully someone will read this and not make the same mistake!

Not sure I understand.  So you just glassed in two little pieces of PVC where the holes exited the stringers? Or a single pipe that passes all the way through the stringer?

[Tampa Bay Mike]

I ripped a 16" piece of pipe in half and layed it on the hull, then notched and set the stringer on top of it. Then I only glassed it down where it touched the stringer when I glassed it all back together.  I should have glued the whole length of the pipe to seal it up..

[mshugg]

I see.  So the water can seep into the foam between the hull and pvc.  Hopefully, the fix isn’t too much work.

[RickK]

I'm confused too. Are you talking about the pipes that are angled forward into the center at the aft of the boat? They look like complete pipes or maybe the picture angle hides something.

[Tampa Bay Mike]

Yeah, those are the ones. They look like whole pipes in the pic but they are ripped in half to fit flush on the hull bottom. Well, at least that was the idea... 

Here's a pic of the aftermath. Luckily I was able to pry most of it up after it kicked.



I think the plan now is to feed a slightly smaller pipe through the existing drain. If that doesn't work, I'll have to grind it all flush and glass it over and then drill a new drain hole. Hopefully I can make something with without too much trouble.

[mshugg]

That should work.  Another option that would leave you with larger limber holes, would be to use a hole saw, and carefully drill through both sides the stringer.  Then sharpen the end of a piece of PVC and use it to push out the foam between.  That way, you can epoxy and glass in a full diameter tube.  The tube would be fraction of an inch above the bottom wouldn’t matter.

[RickK]

X2 on what Michael suggests. Then use some thickened resin to glue it in all around the pipe - keep the pipe short, just wide enough to get across the stringer. You can see what I did in this pic.

[Tampa Bay Mike]

Problem solved, and it actually wasn't too bad. I decided to just grind down the first pipe flush with the stringer and drill another hole beside it for a new one. A little thickened epoxy and a few layers of 1708 and we are back in business. Tomorrow after everything is cured up I'll double check it all and pour the rest of the foam.

[RickK]

Glad it was an easy fix.

[Tampa Bay Mike]

Me too. If that's the biggest snag I run across during this rebuild I will be a happy camper.
