1973 196 rebuild question

[umecheme]

I got a crazy high quote for a below deck tank as well.  I was told that the long skinny thin tank was much more expensive because they were basically charging per inch of weld.  Long means lots of welding...

I guess the $10/gal price is only a pipe dream now.  You could always go to Moeller and price a poly tank. Also check a marine surplus place for poly tanks.

Got new quote for fuel tank at $1800 or 36 per gallon. The difference ensions are 66 inch x 21 wide x 8 inch high plus fill which was an additional 3 inches.

Pouring foam in stringers shortly.

[Duffy1470]

Not really a lot to see. Poured foam in port stringer. Here are key takeaways
1. A gallon of part A and a gallon of part B ALMOST fill an entire stringer
2. I threw all over pour/spillage scraps into stringers
3. If you were to ever make a time capsule, this is the place

Also, big pours are better, at least 24 Oz of a and 24 Oz of b for a total amount of 48 Oz.

Yes, I was advised to put squares of plywood that had been taped on one side with packing tape, over the holes in the stringers. Secure the wood over the holes with duct tape. Then mix a big batch and pour the foam mix into the rear most hole. The foam will travel forward as it expands and fill the stringer.

I used my old gas tank as a plug for a stern corner cabinet for the rigging to come up through.
How many layers of 1708 do I need or should I core it or something?  Suggestions would be a huge help. Right now it's 2 layer 1708 and a layer of mat. 

[Duffy1470]

I used scrap 1708 so kind of Frankensteinish but it worked.

[Duffy1470]

I put the wrong pic in there. It looks crooked because it is. I fixed that. Mostly anyways

[Duffy1470]

Here is the corrected one

[RickK]

The box looks good. It's not a structural thing so the 3 layers you have lam'd for it should suffice.

[Duffy1470]

I guess it will be mostly under the cap so no one will step on it etc. I wonder if I can fit a fuel filter in there? In my m8nd I am waiting on the fuel tank so I am not doing a lot of other stuff. What could I be doing?  Should I grind and lay mat on the sides then maybe put stiffening ribs in, say at 4 feet and 8 feet from the transom? I should probably start on the cap or the console too

[Duffy1470]

Laminated stern cabinet in and foamed starboard stringer. What should I be doing while I wait for fuel tank? I am kind of mentally stuck.  Guess I could raise stringers. I am thinking there is an order of operations and if it's not followed that would be bad. Someone please kick me off the fence.

You could paint the bilge where you'll be able to see it with white 2-part epoxy paint. You can then mount the bilge pump and route the plumbing/wiring. You can solidify your plan and put it in place to route wires and hoses from the console back to the aft, even if it's just on paper. You could start making the 4x4 or 4x2 plastic fence posts to raise the floor.
