RickK's 170 rebuild

[RickK]

Congrats on the foam completion, Rick !  Looks great!  So let me get this straight...You mixed 2 quarts at a time (one quart of each part), and that was enough to fill at least a few feet of stringer?  I'm hoping to foam mine this weekend, so I really appreciate the info!

I want to say I mixed  a gallon when I poured, and I think 8 gallons total, 4 of part a, 4 of part b, 4 lb foam.

Man that's a lot of money in foam

yup, just checked my book, 8 gallons of 4 lb, 4 of A, 4 of B. was the exact amount needed for my stringers

[RickK]

Oh that reminds me - the foam I used is 2lb.

[CLM65]

Yea, the 2 lb versus 4 lb density will definitely make a difference.  I have the 80 lb/20 cubic foot kit of 4 lb foam.  That is probably about what Aaron used, since it came in two 5 gallon containers (probably about 4 gallons of liquid in each).  The way I did my stringers, I'm sure I will need more foam than Aaron did.  Well that is just great.  More money....

OK I have a foam question.  The 2lbs or 4lbs foam... how is that figured?  The weight per cubic foot of the cured foam?

Yes, it is the approximate weight of one cubic foot of the cured/expanded foam.  As I understand it, the amount of expansion is affected by temperature, with 80°F or greater being about optimum.  So if it was colder, it may not expand as much, and would be a little more dense (one cubic foot would weigh more).

Here's a little something for the non re-builders who haven't read it yet.

Three pages but on page 2, a couple three pics of foam.
Look familiar?

One more from the CW group

Opinionated for sure on the foam but many have found wet foam in their Aquas so I'd say it can absorb water at some point in its life.
Interesting indeed.

Congrats Rick! That is a big milestone, at least a mental one for sure!

CB, enjoyed reading that lengthy and quite technical dissertation on CW.  Surprised Jim H didn't end the thread with the definitive reason (his own) as to why Whaler foam absorbs water.  He is, after all, THE expert on everything Whaler...just ask him.

Just checking

Wow that looks GREAT Rick!   It's exciting when pieces start to come together and you can see what the finished product is going to look like.  When ya planning on installing the deck permanently?

[Capt. Bob]

I'm guessing you're sealing the tank hatch with say, UV4000 (good choice by the way ) but what about the aft hatch where the pump is to be located?

Also, is that the loaf of bread Eddie stole during "neighbors nite out" ?

Good luck.

This build is better than the majority of "professional" jobs
