Re: Leaky strake on 2004 Chaparral

I have to grind it and add another layer. I am using epoxy and it is a bit troublesome even with a thickener on a verticle/overhead repair. The glass has been "tucked" up all around behind the hole using a sucker stick and a smoothed hacksaw blade.It extends inside up to the Cap on the strake. I didn't want to cut into that.

Looking good. Won't be long now!

aye .. the epoxy that I use normaly has a Sag quality to it .. it would take a crap load of filler to make it to "PB" .. but it does not seem to stay like Jiffy ..

You just need the backing to glass up on the outside. I would prefer if you ground out more on the outside. Your choice.

YD.

PS. This is why I like VE resin on the overhead lams .

Re: Leaky strake on 2004 Chaparral

What you might consider doing, since epoxy takes so long to set up, is to use a piece of plastic sheeting and put a glob of the thickened epoxy on it and then place it and mold it over the strake and tape it in place. the plastic will keep it from falling out and maintain the shape of the strake. I've done this several times on keels and it works great.

Re: Leaky strake on 2004 Chaparral

Yeah, I didn't think that it was so pretty! Ha,Ha. Epoxy is a lot harder to work with than I remembered. verticle and overhead is a real challenge. I thickened it up (not to PB) and used "fast" hardener but that added problems also. All the angles are giving me fits to. I stopped at the top where the strake intersects with the hull. I would like to grab more area but didn't want to add to the problem.
The horizontal glassing of the strake will be supported with a bracket after the glass is laid up.

Re: Leaky strake on 2004 Chaparral

Again .. Epoxy is a tricky resin to work with if its overhead ..

Re: Leaky strake on 2004 Chaparral

I am concerned about grinding more area of the hull laminate just below the stringer. This is an interesting problem involving angles and not your standard "Hole in the Hull" repair on a flat surface. I am familar with the 12 Rule but not surre how it applies here. Suggestions have been to take it 4" all around . That means laying up overhead/verticle and doing an inside curve. Not bad if the boat is upside down ! West Systems suggested makeinga mold of the strake, laminating a new one and the sticking it on with Six 10 adhesive. That skirts the 12 rule unless you lay up the repair to that dimension.
Anyhow ? Thoughts ?

TRICK EPOXY
Used slow kicker and more thickener the second day and was able to "Finger" it in and smooth it..

Re: Leaky strake on 2004 Chaparral

You could also use some paper. .. have your lams ready to go .. lay them up on some masking paper.. roll it out.. then put up the few lams at a time with the paper on the backside. Hand it up there .. then carefully remove the paper. Then roll out overhead.

YD.

Put the laminate on some 4 mil plastic sheeting and then you can put it place and work the air out, leave the plastic on until it get's hard.

Re: Leaky strake on 2004 Chaparral

I already suggested this^^^ but I guess he doees not want to try it. I always works great for me.

Re: Leaky strake on 2004 Chaparral

Thanks for the suggestions. I was not ignoring them. I will be using them when I go to the external repair. I was trying to build up the hole without voids. I underestimated and didn't mix enough glass/resin to fill the hole so paper or plastic would not have come in contact with the material. Second day mix change worked fine.Original thinking was that FAST kicker would be a help but turned out to be just the opposite in this case.
I used to have to glass the hull to deck joint and bulkheads from the inside on High performance offshore boats. The rope locker was a killer with the stuff dripping down on you. One person wet it out and handed it to you !

Re: Leaky strake on 2004 Chaparral

Got the external lams in place without any trouble using the slow kicker and some silica . Using plastic has the added advantage of not dragging up "Hair" Ha,Ha

Rain and wind delaying work and with TS Dorian coming next week, I will have to squeek in what i can. Thanks everyone for the suggestions.

Re: Leaky strake on 2004 Chaparral

Still battleing an extra rainy season but did get the layers in place. Having to go overhead and around a 90 degree corner caused some problems. Using plastic and working out the air holes on an outside corner did not work well. Came back with another layer to repair. Looks good now and I did the first shapeing and fairing on the repair.

Re: Leaky strake on 2004 Chaparral

Still battling rain at any time of day,Not our usual dependable afternoon stuff, but all faired in and ready for Gel coat. . Anyone know why "G" suggests usuing "Air inhibited gelcoat" ? No wax ?

 

[Woodonglass]

Re: Leaky strake on 2004 Chaparral

Soooo... you used Epoxy for the repairs and now you want to gelcoat over it. That could be problematic in that Gelcoat typically does not adhere well to epoxy. It's my understanding that you need to make special care in your prep work in order for it to work and even then there's no guarantee it will stick all that well. But hey, I'm no expert on the subject, just passing on what I've read on the subject.

Re: Leaky strake on 2004 Chaparral

WoW, I just looked at the date of the last post. Time flies. I have been battling untypical rain patterns and it has been a pain. I finished the repair and set the boat in the water for 6 hours and no water leakage. i went to crank over the motor but I had an electrical problem from sitting so long. Started to ttroubleshoot it when....you guessed it, we got 1.2" of rain. I had checked the weather before going out and it was clear. I went right back in and checked it again and we had a T-storm bloom up right in our local area ! Nothing for 50 miles around. ?? Got to resolve the electrical problem a few days later.I will load a finished picture.
