Re: Upon Further Review..#$%@..1973 Slickcraft Trans/String Overhaul

Hey red. How goes it? I'm not trying to cut any corners. I'm going to pull the inner skin off and see what's going on. Last night I made a new discovery. It appears my boat has been in an accident of some sort. Either backed into something or something hit it. I never noticed before, but now that everything is out of it I noticed something looked different. There has been a repair made to the port side of the transom. Up underneath in the corner there is some extra wood and some shoddy glass work. No suprise, that is where the wood is rotten around the lift hook too. Not on the other side. Mrs. Mulligan has the camera at a function today, but I'll post some pics of this later.

steve,
Here are some pics of my keel stringer. The engine and fuel tank sole are at the same height on my boat, but it is posible for it to step up or step down whereas the keel stringer would be taller in one area. In my helm area the keel stringer has a piece of plywood directly on top of it and a piece of ply on either side to clamp it on place. This allows it to reach the bottom of the sole. Does that help any?

Here is what I was talking about yesterday......... You can see where someone did some really poor glass work around the mounting block for the lift hook. Never noticed til I got the motor and batteries out. Obviously something happened to this corner of the boat, which makes me want to be able to stand across from the person who sold it to me 11 years ago and didn't disclose this info. I'd like to get ahold of him and ...........well, nevermind. What's done is done.

Well, looks aren't everything, especially when it comes to glass work. As long as its solid and the proper prep work was done, it should be strong.

Is it separating or cracks showing up?

Re: Upon Further Review..#$%@..1973 Slickcraft Trans/String Overhaul

Mark, the transom is rotten in this area. Behind the big block for the lift hook. Not just the block, but the transom as well. The area is strong, I've run it in heavy seas for the past decade on the great lakes.

Good chance that someone backed the boat up with the motor down and cracked it...I think that is one of the easiest things to do to damage a boat...carelessness. Probably tried to back the boat up with the motor too low and hit a hump of dirt or curb or who knows.

Re: Upon Further Review..#$%@..1973 Slickcraft Trans/String Overhaul

Red, i'm not sure. I'd think if that was the case the damage wouldn't be confined to one side. Anyhow, i'll know more once the skin is off.

Got my plywood from a lumberyard today. They estimate it at 18%. Talk to me about drying it. Can I do it in my garage with a fan and some halogens. How long?

oh, it's outdoor ply a-c

Re: Upon Further Review..#$%@..1973 Slickcraft Trans/String Overhaul

YEp ooops got me using a fan on it !!! the light will help alot , but your looking at 2 to 3 weeks drying !!! John

they estimate.......BAAAA HAAAAA HAAAAAA......they dont know what they are talking about.....try 45% or more.......

plywood when dry is very light.....was it light??? ....sit it in as warm a room as you can and put a fan on it.....the hali light will work great as long as you keep moving it around and flipping the wood......you will notice a big difference.....but the most important is to keep the fan on it.....keep the air moving.

ok.....im looking for your other questions now.

Re: Upon Further Review..#$%@..1973 Slickcraft Trans/String Overhaul

ok guys, need some advice on materials. I've decided to go with epoxy resin. I'll need fiberglass for the following:

Transom: Over 1 1/2" of marine grade ply

Stringers: 2 ea. 3/4" by 13 ft. marine ply if i have enough after transom.

Bulkheads and Deck: 1/2" outdoor ply

So, i'm not looking for calculations on how much of what to buy. I'll figure that out. I'm looking for advice on type of glass and weight for each part.

Oh, and the deck will also have a layer of 1/4" teak on top of it.

any advice will be appreciated.

O.k. thanks Ondarvr. I can buy that. So, for the transom and stringers two layers of 1708 biax? I'm using epoxy resin. Want to make sure it is enough.

ondarvr is correct........the 1708 bi ax will be just fine.....even tho the csm side is not needed with epoxy.......it will be bulky enough and strong enough for what you are doing.......i would also get a small quantity of csm (scraps)....just because its a cheap tacking product and can come in handy

No , what i was trying to say is that matt is not needed with the epoxy !!! I really dont think it will hurt , but it wont add any more strength to it !! wouldnt it be better to use just plan old glass with out the matt ??? JOhn

its true that the 17 oz cloth does not need a csm layer because of the epoxy....but the over all product will have more stregnth with the combined product instead of the knit alone.


any thing else......just message me
cheers

Re: Upon Further Review..#$%@..1973 Slickcraft Trans/String Overhaul

oh yeah i forgot.........the damaged area.

chances are it will be rotten in there....if the p/o did a carpy job of glassing that area.....he didnt dry the damaged area before he made the repair.

with all the transoms that ive been looking at lately.......99% or all transom rot comes from where it has been drilled thru......be that a transducer....a speedo mount or a swim grid thru hull bolt......

people that put the add on's on....dont take the time to reverse the screw or bolt and fill the hole with epoxy or 5200......eventually you get water intrusion.....and finally rot...


the campion we just did had a bad transom......the rot started at the place where the owner put his transducer.......that rot spread from the transom to the stringers as the foam stringers soaked up the moisture from the transom.....

simple lesson......the bad transducer mount cost the owner over 3 grand....just cause he didnt fill some screw holes.

Mike,

Thanks guys,
83, I'm sure yours will. The question will be whose is done first!? The way work has been and is going to be for awhile, I won't be spending any dough on boat materials any time soon! I've got other work I can do on it though in the meantime. Looks like your headed in the right direction 83. Getting some good advice here. You do realize that once you get so far into, you could find it took a port side torpedo hit and all it is is another yard of glass and some resin, no big deal!!! I think that's how oops!'s REALLY started. He just cut out the bad part of the hull!! Keep up the good work!

Re: Upon Further Review..#$%@..1973 Slickcraft Trans/String Overhaul

John: good seeing you today. Boat is looking great. Eye Of The Tiger, bud, you are NEARLY there!! I'm on it with the fan. It's all in my basement now, will run the fireplace at times when I'm home. Keep the fan on it all the time.

Oops!: Thanks for dropping in. Really appreciate the advice. Yep, tore into the repair area tonight for a little bit. It wasn't a good job by the po, I didn't even need a grinder to cut the fiberglass. Just used a cats paw and dead blow hammer to cut along the edge of the block. thanks for the input on the glass type too. Two layers on transom and stringers, or is one enough on strings? what about on plywood edges (i'm thinking bulkheads). Should i use a lightweight cloth or mat there?

58: I'll be happy for the August run on Kings. I won't have any money to fish even if i finish before that. The economy is brutal, eh. It's sad to see our state in such a financial mess. I've got a lot of friends out of work or really hurting right now. I'm grateful for my job for sure.

Re: Upon Further Review..#$%@..1973 Slickcraft Trans/String Overhaul

Ahhh! at long last.......the sight, the smell, the pageantry of finding my first rotten transom! Was getting too late to keep digging, don't want to upset the neighbors so early in the project. I wanted to keep on going though.

 

[oops!]

Re: Upon Further Review..#$%@..1973 Slickcraft Trans/String Overhaul

83 go a double wrap on the strings......it will last forever.....

as far as the wood edges.......depending on if they are structural or not....the epoxy will waterproof them well.....so if its just a waterproofing situation then just use what ever you have left over.....

id suggest you try the dowell diagrame on the hull ext thread....it is a little more prep work.....but it will save you a tonn of headach in the long run.....unless you are going with 1.5 or 2 inch stringers.....

Oh yeah, I remember reading through your pain of trying to wrap those stringers, lol. I've been thinking alot about that. Either biscuit jointing a half round piece on top of the stringer, or taking it a step further and using a dato blade to cut a 3/4" slot and a router to round over the top and cove the edge where it meets the stringer. Glue it on like a cap for an I beam type bulb on top.

I'm hoping to find a lot of water logged foam so i have some weight to take out. I don't want to make the boat any heavier than i have to because i have an old, somewhat tired 165 and I'm adding about 130 to 140 pounds on the back in the form of a yamaha t-8 and bracket. I have to be careful I don't make it a trawler.
