Re: First boat Resto in progress " advice needed"

You are correct!
I just saw white stuff at the base...
I always recommend getting a layer of carbon fiber on to your stringers. you can slap one on now. You never know!

Why.

Re: First boat Resto in progress " advice needed"

two layers of carbon fiber = 6 layers of fiberglass.
Weight to wet ratio favors you better and is stronger.

Re: First boat Resto in progress " advice needed"

Thank you very much for showing me this thread Captmello!!!!! This is almost just like my boat, same interior colors and all! Mine is a 23' cuddy though. I am finally getting ready to hit it again, The weather around here hasnt been to great this year "rain" and when it was nice I have been fishing in my fishing boat I have to work on it outdoors, anyway I am just about ready to get started on this slow procedure again but my biggest thing is I want it done right! So eventually I will get'er done. If I take my time on it I enjoy it more so I dont care how long it takes. Thanks guys

Re: First boat Resto in progress " advice needed"

Uh OH, I may have made a Boo Boo! I purchased and tabbed my first stringer with 1.5 chopped mat but I am using EPOXY???? I did use a very generous amount of epoxy though so I hope my tab job is ok? It seemed to go well. Anyway I am guessing I am not suppose to use CSM? What do you guys recommend I get and how many layers should I use on the stringers and how many on the motor mounts? I would like to use multiple layers of light weight cause I have alot of corners and edges to go around! Please help, what do you guys recommend? 4oz. Cloth? Would the CSM be ok to use for the sole since I have so much of it? I don't want it to go to waste Thanks

Re: First boat Resto in progress " advice needed"

It's not that you can't use CSM with epoxy, it's that CSM is not needed with epoxy, plus it sucks up a huge amount of it and adds relatively little strength when compared to woven or stitched fabrics. This results in a heavier and far more costly laminate for the same or less strength.

4 oz cloth is too light, 10 oz or heavier would be much better, or a biax like 1700 (not 1708).

For the floor CSM will do the same thing, it will work, but will use 2 or 3 times as much epoxy...$$$.



As for the comments on Carbon Fiber?. CF is extremely expensive and more difficult to work with, to use it on a repair of on older ski boat is sort of a waste of money.

Re: First boat Resto in progress " advice needed"

Thanks Ondarvr, I understand. I guess I need to purchase some woven cloth then at least 10oz or more. How many layers of 10 oz cloth should I use on the stringers? I am a newbie to glassing as you might guess. Please consider the fact that I MAY not be refoaming my hull so I may want to make it a little tougher, so what would you guys buy and how much would you use? I hate the foam idea, my boat never and I mean never got water to the bildge with the foam in it so I am kindove against it, so I would like to skip the foam and beef the stringer system. Advise anyone?

Re: First boat Resto in progress " advice needed"

Hi guys, I am planning on ordering a roll of glass tonight. I found some 12oz. E-glass cloth at a reasonable price, what do you think about that? I am worried about it being to heavy and hard to work with! I read about alot of people using 7oz for boat projects I hope the 12 oz is ok, I have alot of corners and edges to run the glass over, the edges have been rounded over with a router and there are fillets in the corners but still I am worried that 12oz may be to heavy? How many layers of 12oz should it take on the stringers " approx" ? I do want it sturdy bit not to the point it is a waste. Comments anyone? Thanks again for the help I appreciate it!!!!

Re: First boat Resto in progress " advice needed"

Phazer,

Since you are doing 3/4 inch stringers, you really need to re-think the process a bit. I have included a drawing on how I recommend doing it and the materials you should use. I have taked with some of the PROS on the forum and they are in agreement with this method. It's your boat and you are FREE to do it how you see fit, this is just my recommendation.

Re: First boat Resto in progress " advice needed"

Thanks woodonglass for you reply! The photo is almost like I did mine but I have alot more than a 1/4" of PL under my stringers cause I wanted to use 3/4" wood instead of the 1/2" the factory used, ya see there is deep groves in the bottom of my hull and they had the stringers sitting in these grooves " so I couldnt use dowels", so I basically filled these grooves with the PL and I used angle iron to hold the stringers vertical and off of the hull " floor simulation" and filled the gaps with the PL and then fillet the bottoms " which I will try PL concrete next time due to gassing bubbles" There is alot of PL under my stringers due to the grooves but I belive it will work fine. I may do it the way the photo shows, however I will be adding clets to the tops of the stringers which will make them widere at the top anyway, this is where I am having a hard time deciding what and how I am going to do this! 1. I could attemp to wrap the clet individually and add the clet once the stringer is already glassed or 2. I could bond the clets to the top of the stringers and try to glass it all together which will make the stringer alot wider at the top. I want to add the clets cause this was how the boat was when I tore it apart but they didnt even bother to glass the clets or the tops of the stringers at all! wonder why it rotted, huh? You do know I am using Epoxy right? Is this diagram good for someone using Epoxy? if so that is great cause I got about 100' of 1.5 CSM I would love to use, but like others say that CSM will suck that Epoxy up! which = $$$ I love the diagram Woodonglass but is this really for me using Epoxy? and do you guys think it could be possible to wrap the tops with the clets added or do you think I am still asking for trouble? Trying to wrap with heavy glass would scare me a bit, I dont mind capping but what good is that going to do me with a clet? I would still have half of the clet unglassed unless I try to wrap them seperately. So many ways to attempt to do it and probably only one good way, my problem right now and has been on my mind for quite some time now is how I am going to attemp the job.

Re: First boat Resto in progress " advice needed"

MY BAD!!! NOPE, no CSM with Epoxy, Cloth ONLY!!!! Coat the wood with epoxy then lay the lams up the sides to tie em to the hull. Two lams of 18oz Biax should do the trick. I would NOT worry about wrapping the top cleats with cloth. Coating them with epoxy will be good enuf. Much better than what the factory did.

 

[Phazer230]

Re: First boat Resto in progress " advice needed"

Sounds good Woodonglass! I coated all of my stringers and clets with "CPES" first then coated them heavily with Epoxy. All stringers are marine ply. Soooo, Woodonglass if I were to order like 12oz. cloth do you think it would be possible to wrap them with the clets, or is it just asking for trouble? I hate the idea of capping but I will do it if I have to! Could I get away with doing this job period with 12oz? and if so how many layers would you reccomend? My clets will look like the photos minus the C-clamp. hehehehe

Re: First boat Resto in progress " advice needed"

Epoxy is STRONG as Heck!! EXTREMELY waterproof. Much more so than Poly resin. Lookin at you latest pics, I would use two layers of the 12oz cloth to tab the stringers to the hull. First one would be half way up the stringer and 4" out on the hull. Second would be to the top of the stringer and 8" out on the hull. I would NOT worry about putting Any cloth on the top. They will be fine. NO WATER will penetrat the epoxy. The cloth will just add additional strength and you really don't need it there. That's my opinion.

Re: First boat Resto in progress " advice needed"

P.S. by the way, I did tab one of my stringers with CSM and Epoxy as you can see in the previous pics, it worked out fairly well but drank the Epoxy, I am going to ditch the CSM of coarse and purchase cloth and go over it with the cloth, I hope that is ok. I only tabbed it with 2 layers and used alot of Epoxy, it is solid as a rock! The rest is cloth from here on out! Live and learn, I did a ton of research but must not have done enough in the glassing section, that is why I need you guys! Thank you for the help.

 

[Woodonglass]

Re: First boat Resto in progress " advice needed"

Yep CSM and Epoxy don't mix real well. Put some cloth over it and you'll be fine. You'll have it on the water in NO TIME!!!

Re: First boat Resto in progress " advice needed"

Glad to hear it Woodonglass! I Epoxied the wood tremendously! I still may glass the tops just for extra strength and just for prevention, I know how alot of people may think about this but I am really considering ditching the foam idea, this is one reason I want my stringer system very strong! I hate and I mean hate the foam! I hate it cause I saw what it did to my boat! In the 10 yrs. I had this boat when I would take it out on the lake and spend the night my bildge never kicked on and I never and I mean never had water in my bildge compartment! I wondered why and I just figured it was a great sealed up boat that just never got water in it, WRONG!!!!! Later my friend and I had to reignforce my trailer roller brackets cause they were bending and scrapping the hull, I wondered why but just didnt think about it long enough, I know now! It was because of the extra 2,000 lbs. of water in the boat that the foam sucked in ARRRRR! " at the time I had no idea what it looked like under the sole of a boat, I didnt even know it had that much foam in it" The foam was in there so tight the water couldnt make it to the bildge, " no voids but no drain, sponge" not to mention no water passage ways in the stringers, which has been takin care of. I know the foam is safer, it is quiter, it would make the hull alot firmer, but at what cost? I just dont think it is worth it , especially on our small lakes, it is not going on the Ocean but I still want it very strong and built right so it lasts a very, very long time. I absolutely love the boat and have had alot of fun in it in the last 10 years. I am no boat professional resto man, but I am willing to learn and so far I am kindove enjoying it, I will be very proud when it is finaly finished and back on the water again. I hope it all holds together hahahah. Thanks

Re: First boat Resto in progress " advice needed"

You could put the Blue Plank stuff in from Lowe's. It will NEVER absorb water.

Re: First boat Resto in progress " advice needed"

I would consider it Woodonglass, I am not to worried about it sinking though " I'll run it up on the beach if I had to, not huge lakes I go to" , I would be more worried about the extra noise and sturdiness I will loose without the foam. I hate the idea of blocking any of the water flow to the back of the boat, if I put anything in there it will naturaly block the water from going to the back, if I dont put anything in there there is no way the water will stay in the hull, it will run straight to the bildge area when the boat trys to plain out and when pulling it out at the ramp, my drainage holes ought to work perfect. I like the idea of foam, I just dont like what it really does. It is probably great if you ever needed it, but most times ya just really dont. If the hull cracked it would be a boat saver but hopefully that never happens. I am surprised that the weight of the foam did not bust my hull and ruin my boat completely to be honest, I am not so sure that it wont be a honest 2,000 lbs lighter after the rebuild! I mean that foam was HEAVY and so was the rotted wood! It was saturated I could not belive it. I just ordered 60" wide 50 yds. of 12oz. E-glass cloth, so I should be able to get back on this job real soon I hope. I need to order more Epoxy soon to though, funds are short but I will make due. Thank you

Re: First boat Resto in progress " advice needed"

Using the Plank, would give you the ability cut drain channels in the bottom plank to allow drainage to the hull AND at the same time Quiet the hull and provide the safety floatation factor. I really have a hard time finding negatives using the stuff.
