Stringer Replacement Harris - materials, process, options........

[HiZ]

Ok,

My friend has a Harris Float boat, deck style with a 5.7 and Alpha set up
We have removed the power and both stringers are gone. (like a sponge)
I have found the spot of water intrusion, drilled drain holes (non-sealed)
So, we are going to tear out and replace them. Bulkhead is ok, Transom ok.

What products should we use and what process.

I know quite a bit about glass and lamination.
But can we laminate on the inside only
Or do we need to secure from the outside also?

Just some of your expert thoughts on this........

Thank you

This should be a good thread.

Got some pics?

 

[HiZ]

Working on it..................
I will have some shortly

That should not be very difficult. I just rebuilt the entire transom and beefed up the stringers. There are plenty of guys on here that can give expert advise. You can use marine ply for the stringers, 1708 biax glass, you have a few different choices for resin, I used viynal ester.

EPOXY , EPOXY , EPOXY http://www.uscomposites.com/specialty.html I know this stuff can sometimes cost a bundle and like i stated in a different thread these guys have great prices and sometimes are hard to beat but then again these guys offer great pricing also www.michiganfiberglass.co but you must call for pricing

Polyester resins have a strong odor that stay around. I would not use it on any type of attached garage.

Ok so engine is coming out and the boat is going to be a start of ripping out the old stuff!
Laminations of the new stringers to start with marine ply.
Are there other options?
How do you work the angle of the hull to the new stringers
How do you fasten stringers to the hull
Layers of mat then cover with cloth?
thoughts ideas


Main question:
What do I clean the bilge with?

 

[HiZ]

Prepping the bilge glass?

Grease and oil, what do I use?

 

[phragle]

Looking at the motormount sunk into the stringer, you sure thats not a wellcraft??

As for cleaning it, your getting ready to rip it apart, coat the thing with a couple cans of engine degreaser then hit it with a pressure washer. Before you even start back there, cover the deck from the engine compartment foreward with plastic and tape it down good or your going to get ground fiberglass in the cracks of the seats etc.

:iagree:

 

[Offshore Ginger]

After you degrease could you post more pics of that area and the cockpit and have you determined just how much of your stringer system you might have to replace at this point and with that in mind is there the possibility of you having to cut the liner out to repair everything that is rotted because sometimes these type of jobs can very well be like opening a can of worms ,if you know what i mean .

 

[HiZ]

I will do that!

 

[HiZ]

So, looks like there is some Gunk growing from the rotten wet stringer on the stbd side! WOW>
I also seem to have found the issue, Nonsealed stringer drains that are flush cut, 5/8" hole drilled in the front of the stringer, No sealant on the engine mounts, and A Damn Diet Pepsi in the Bilge

 

[HiZ]

So, this sucker is nice! it's a 95 and completely ROTTEN!
Also, that is power steering fluid
thus presenting 2 questions:
1)how do you remove w/o draining
2)how do you bleed and fill
3)There are only 2 questions

 

[HiZ]

So what do you think

 

[HiZ]

Can anyone tell that it is maintained well by the clean fresh hull!?!

 

[MOBILEMERCMAN]

I like GREZ OFF its my favorite degreaser. Acetone will work well to. Plug the power steering lines and tie wrap up out of the way.

 

[HiZ]

Yes sir, 5 cans just picked up at O'riley Auto for $1.99 can! WHEW
So, this is going to get messy!
HANG ON>...

 

[MOBILEMERCMAN]

After you clean it. Measure and draw what you have before you start removing material. Take a good look at the transom too. Hopefully it is not rotten too.

Getting messy is an understatement.

Ok, got that.
So, what's the deal with fabricating the new stringers?
How, per say is the best way.
Plywood lamination. put in with the seams perpendicular to the hull?
Stacked solid wood?
Hardwood laminations.
What's the best way, technique
