fiberglass repair: bow eye

[terb]

got a little backwards on my pic's upload hey i'm old. have a 22-2 aquasport c/c the pic's are of the anchor well i cut open to get access to repair. any experience here? is epoxy resin/glass work really one layer at a time ,cure and do it again. everything i've read so far says epoxy resin for structural repairs . somebody has done a poor job of repairing this before.bow eye was moving when hauling out boat,so i thought i'd fix it. opening a can of worms, there is almost nothing supporting the area where bow eye was. i can glass this but any input on how to get enough bond to old glass.also have old resin repair,cut out what i could but can get more of it ,the green stuff,will i be able to count on a bond to that. i can clean and get to maybe 6 inches each side of cut out.hopefully have pic's if i can get them up.thanx

Re: fiberglass repair: bow eye

i gotta get to work so im hoping another pro can jump in and elaborate more on this.........the bow eye MUST BE ONE OF THE STRONGEST AREAS IN YOUR BOAT.... no green body filler here.!

im realy mad at the manufacturers for this........who makes aqua sport?

you will need to really repair that area with backing plates and fiber glass.

search my thread for a pic of the bow eye from the inside.....it will be in the first 50 pages.

when i get home form work ill tell you haw to fix this.....

but again.......the construction of this area is just plane wrong.

Hello terb..and welcome to Iboats..

Your going to learn how to grind and fair .

First off the inside glass needs some serious grinding. From your your post you dont have any more room to expose the repair..so that makes thing a little more difficult. Your going to need to grind and feather as much as possible removing that dead glass in there. Removing All that Green stuff....hmm.. I probably would NOT ( just looking at the pics judgement thing ).

Feather the inside as much/best you can. Mask off around that cutout you made. 3 layers of Masking tape on the Outide of the repair closing that hole. On some cardboard wetout and bubble roll 4-5 layers of 1708 and 1 layer of 1.5 oz mat. Resin coat the inside repair area. Grab your Fiberglass bandaid ( Glass should be as large as you can make it for the reachable inside repair ) slip it in that hole..and use your hands to pressure/lay it down. Use a brush to help smoosh that glass down as good as humanly possible.

Let that cure.

Now goto the outside and start grinding/feathering 5-6" around the hole ( enough depth for 3 layers of 1708 and 2 layers of 1.5 oz mat.

Apply 1 layer of 1.5 oz mat..then your 1708..then end with mat..

Grind/fair..fill and fair..prep and spray gelcoat and finish. ( we will get into the gelcoat proceedures later if it comes to that ).

Get grinding and take some pics .. report back .

Re: fiberglass repair: bow eye

Yd, we must have gone to different schools together
The same school of hard knocks!

I could only second what you suggest!

Terb, follow the Dr suggestions, ask some questions if you don't understand.

Re: fiberglass repair: bow eye

YD,thanks for your time.can you elaborate on dead glass,is there a point i can reach bondable glass. if i widen my access hole a little more, grind down to it.is it even going to be there on this old boat? am i correct in using epoxy resin. also your instr. on laying 4/5 layers of 1708 ,1 of mat,can this be done in one application.any wait time in between layers? have a stainless plate formed and drilled for the outside so i'm on the same page with that.have a 1/2 alum stock plate,4by6 for the inside backing for eye. just wary of getting a good bond from the first layup.can i start with strips of cloth to bring the valley up,cut down my angle.thanks again,tom

Hello terb..

Basically you want as much of that white delaminated glass out of there..

I would use poly or vinylester resin..not epoxy..

You would wet out ALL 4-5 layers of your glass on the cardboard at one time..then peel that whole thing and put it on your repair as outlined above.

You want to resin coat the repair first..then put your 1.5 oz ( cut to fit ) in there..wet that out..then apply your prewetted 1708 on top of that.

Yes if you can build up that little valley with strips of 1708 ( 5 layers at most in one session ). Start and finish with 1.5 oz mat for those "build" strips. Feather after that and then apply your final mat+4-5 1708 lams stated above.

If you need nore info dont hesitate to ask .

you guys and your wet out boards....... CHEATERS ! lol

do as yd suggests or you will have resin running all down your inner and outer hull

i would also add a big (form shaped) chunk of hard wood in the nose and glass that in as well.

the bow eye hook has to be one of the strongest hooks in the hull. it is there in case of trailering accident.

if you get into a head on......and the glass fails...you will have a sail boat....(as in sailing thru the air)

thanks for helping out when i was at work yd

cheers

Re: fiberglass repair: bow eye

have a 1/2 alum stock plate,4by6 for the inside backing for eye

You think this will do instead of wood oops ?


OOPS " thanks for helping out when i was at work yd " .. hey man...no problem..

Re: fiberglass repair: bow eye

The practice around here is to remove all core/wood from cleats, bow eyes, structural areas..that will be thru bolted, and use solid glass and/or with an alum. backing plate. Our thinking is failure normally comes from the sandwich material before the laminates, due to over torqueing of bolts and the necessity to bed these parts frequently to avoid water intrusion.

Having following what did with your boat and others, oops.
And understanding YD's knowledge.
They know what it's about......BUT...
I humbly disagree. :facepalm:


I like solid, long lasting material, that can believe in.

Good Luck!

Re: fiberglass repair: bow eye

Backing plates like alum should be used when longer bolts are used..

Ive even seen over backed cleats ripped out causing more damage then needed.

There is a fine line when you cross over protection vs just let it go.

But I would most allways alum or glass back/block my throughbolts.

no sweat sasto......reguardless of the material.....the point was just to back up the glass.
ols school is wood....but a nice chunk of alum plate or what ever is great......just as long as there is some kind of backing plate !

Re: fiberglass repair: bow eye
