Need some clarity on 'glassin new stringers/deck

Re: Need some clarity on 'glassin new stringers/deck

Nothing really comes to mind on an address where I could have the stuff shipped... I really don't know anybody around here that has a business! I guess if it came down to it, I could butter up the guys at the marine shop... I'll keep that in mind.

I agree, it is largely about the money... I don't mind paying the shipping, but I still want to find the best deal and the best way to get it shipped. If one way is cheaper than another then I want to go with the cheaper. I understand why they have to charge the hazmat fees... It does make me wonder though why they can ship one bucket and charge the hazmat fee, but they can't ship two and just charge twice the fee? I'm sure there is a reason...

I don't know why I hadn't though of this before, but I guess I could just order one bucket at a time, that way I wouldn't need the commercial address. Hopefully they will call tomorrow to complete the order and we can figure it out.

Thanks for the ideas guys... maybe I'm not the first person to come across this problem. I'll keep you updated..

Edit: Yacht Dr., what is CCP? Is this another resin supplier?

Very interesting website... looks like they have some good stuff there. Shame they don't have a distributor within a few hundred miles of my town... thanks for the link!

One of our iBoaters used these guys and said they were great to work with. You might check them out too.

Re: Need some clarity on 'glassin new stringers/deck

Thanks Woodon, I've been looking at that site too... they have decent prices on the resin, not quite as cheap as USComposites though. Their site says they don't sell the stuff in 5gal buckets so I was looking at other sites first. I'm definately keeping them in mind though...

Re: Need some clarity on 'glassin new stringers/deck

Looks like USComposites came through for me after all... I guess they CAN ship freight to a residential location. Very nice and helpful folks over there. I hope 10 gallons of resin and 20yd of material is enough to get it done! We shall see...

Getting anxious now!

Re: Need some clarity on 'glassin new stringers/deck

Glad to hear it. Its been several months since I have ordered any resin from them. But back when I did, it was in 5 gallon buckets. I was ordering single buckets at a time though. I thought they may have changed their policy or something. Did you get the 435 resin?
here are some other stuff you may need

cabosil and chopped fiber- for making fillets
talc- also a filler, saves on cabosil
finishing wax- for the top layer of layup, seals surface and allows resin to cure completely. also for top layer of gelcoat for the same reason
grooved roller- 1/4" and 1/2" recommended
cheap paint rollers- get cheap ones with a medium deep nap 4" and 9"
mixing cups- quart size, home center has the plastic ones, paper ones are cheaper
stir sticks- free at home center, get some tougne depressors too very handy for small amounts
gloves- i prefer the vinyl ones
chip brushes- buy a case at a time, you always need them and its cheaper that way.

I'm sure I'm forgetting some stuff but that will get you started. Oh, and dont forget your safety stuff.

Re: Need some clarity on 'glassin new stringers/deck

I got the general purpose resin. I had read that is what is usually used... I hope that's ok? I didn't order wax... Guess I slipped on that one! Do the stringers need to have the wax on the last layup or just the deck? I've never worked with fg before so I don't know how tacky is tacky?

I pretty much got all the other stuff on your list.. only other thing I didn't get was the talc. The only part I plan to use the cabosil for is to make the fillets around the stringers. I got 2 1/2qt of cabosil.. hope it will be enough.

I still need to get a respirator...

I figure I probably have a week before the stuff gets here so that gives me time to make the stringers.

And the fun begins...

Re: Need some clarity on 'glassin new stringers/deck

I have never used the general purp resin but it should be fine. The stringers and everything under the deck should be ok without wax, but you are going to want it for the deck if you are gelcoating it. You will need it for the last layer of gelcoat. If you dont use it the surface will feel tacky on your feet.

tip on mixing fillers- use less resin than you think you need. it does not take much resin, but it will take plenty on cabosil. mix it to a mayo consisitancy where it sticks to the stir stick and does not run. also put the hardener in and mix well BEFORE adding the filler. Use a little less hardener than you would for resin to get more work time. it will take a few trys to get the hang of it. mix small batches at first until you get the feel.

Re: Need some clarity on 'glassin new stringers/deck

Ok that sounds good.. I'm actually planning to put a good carpet on the deck, either by gluing or snaps/velcro. I'm thinking I should be ok without wax on the deck in this situation?

 

[drewpster]

Re: Need some clarity on 'glassin new stringers/deck

yes, but your carpet may stick to it over time. see my earlier post, I added to it.

Re: Need some clarity on 'glassin new stringers/deck

Ok, so add resin + hardener, mix, add cabosil, mix, add cabosil, mix, etc until mayo consistancy, right? Should I expect to use more cabosil in volume than I do in resin/hardener?

How much of the PL should I put under the stringers? Just enough to raise it off the hull, say 1/4"?

I'm trying to get the order of operations straight in my head here...
When I get the stringers bedded down in PL, will the PL be enough to hold the stringers in place while it dries, or should I be prepared to mix some resin and have some fg tape ready to tab the stringers to hold them in place while the PL dries?

Yes, start with a small amount of resin and add cabosil. If it gets dry add a touch of resin. Some say mix the hardener after the filler. But in my experience you end up with way too much hardener that way. Be accurate with the hardener. The little measure that comes with the MEKP is used for that. Keep it clean and use it for hardener only.

1/4" is plenty. You should be able to get it down to 1/8" if you take your time fitting the stringers. You want just enough to keep the wood off the glass.

I used some bracing to keep the stringers upright and in position until the PL dried. After it dries it will be solid if you have a good bead under the stringer. Then remove the bracing and start the layup. You could insure nothing moves if you lay in a couple of tabs.

Re: Need some clarity on 'glassin new stringers/deck

The only reason I mix the filler to Poly resin ( cabosil in this case ) is Time.

If you kick off the resin then add the cabosil your loosing working time with it. You also might add too much cabosil and then have to add resin .. You mix will generally take a 50-50 resin to cabosil by VOLUME depending on your thickness of the resin to begin with.

There are a few things Drewps way has over the mix and kick way. Your more accurate on kicking and also adding MEKP to putty can sometimes lead to a pocket of mek that could kinda squirt on you if your not careful.

Experiment with a small batch to kinda get a feel for your working time.

Peace out YD.

Re: Need some clarity on 'glassin new stringers/deck

Ok... so the glass stuff will be here Thursday (thanks USComposites!) so I'm scrambling to get the stringers cut and the motor mounts in place.

When I tore out the rotten stringers/deck, there were a few pieces of wood that were stretched from left to right across the tops of the stringers. They looked to be like 1x2 lumber. Am I correct in assuming these are for added deck support? Is it ok to go back with the same lumber as original? Fir maybe, if I can find it locally?

You can see the spots in the foam where these supports used to be (no, they weren't glassed in either)

I'm also wondering about adding addition ribs(?). There were none originally, except for one in the back by the motor mount. Should I add one or two more to add support, or just go back the way it was? The only reason I'm wondering is because I don't plan to put foam back into this boat so I want it to be solid.

Last thing, the original stringers were only 3/4" thick... Does this sound right, or does it have to be doubled to get 1 1/2"? Looks like the stringers, bilge box, ribs, etc were all from 3/4" materials.

Off to Home Depot...

Finally uploaded some pics... if anybody is interested. Click HERE. It's a photobucket album...

Re: Need some clarity on 'glassin new stringers/deck

The best way to tell if you will need to add more supports is lay the plywood down and walk on it, if it flexes too much then add them as needed. Remember the ply will be stiffer with glass on it.

When deciding on how to "improve" on the original design (stringer thickness in this case), look at how the original build survived in use from the time it was built. If it functioned without failure there isn't really anything to gain by making it stronger. Without re-reading the entire thread I think the only issue was rotten wood, so the area you need to make improvements over the original design is in the quality of the glass work, which normally is fairly easy to do.

Take one guess at what I've been doing today...

Very itchy... almost done grinding though.

Nice work. Almost time for the rebuilding phase!

Re: Need some clarity on 'glassin new stringers/deck

Looks good so far i would definatly inspect your transom you will kick your self if you dont. your at the point i would just do it to know its good. if your stirngs were wet/ rotted i would say the transom is to or on its way...good luck
What brand/model is your boat?

Re: Need some clarity on 'glassin new stringers/deck

Looks like you did a great job grinding and sanding that old glass down.
All of you guys are an encouragement to me. I am doing the same thing for 2 projects, that I am doing at the same time. a '59 Biesemeyer and a '73 Chrysler.

You can check out the BeastMeyer (Biesemeyer) here http://forums.iboats.com/showthread.php?t=449445

Any help would be great, keep up the good work dccordell
I will be doing the same for mine real soon and will post pics.
