Timid but determined Glasstream restoration

Re: Timid but determined Glasstream restoration

Hello all,
Thanks for the advice and encouragement. Renting one is a Royal PITA, I'm gone to much and it's hard to pick up and return.
My DA uses about 7-9 cfm at 90#, The one I'm looking at will give me at least 14.5 cfm. I know arch yours is 18 cfm, I'm still looking at the IR and may go that way yet. To many decisions,.

My sander is a 12 inch so and I keep it moving down the hull to make sure it stays flat. The gel coat that is still on the bow is only a very thin layer. I don't think the glass is very flat from the original build. It will be when I finished.
The only reason any of it is shinny, is because it's still wet from the water hose.
Take care
Bob

Wow, and I thought you'd sprayed the stern area on the port side! Making progress Bob...

Thanks Triton II,
It's progress but that is the sum of about 10 hours of sanding. At this rate I may be sanding all winter.
I have started going over different color idea and patterns for the interior. At least being away from home gives me time for that.
Take care and thanks for stopping in.
Bob

Re: Timid but determined Glasstream restoration

Prep is the key, just wish I had your patience...looking good. wax on wax off my friend!

Re: Timid but determined Glasstream restoration

Thanks arch and HSF,
I'm not sure I'm really that patience.
Maybe getting away for a few days Will help me stay the course. The more I read the more I question my sanity, or is it insanity.
I hope all is good in your world.

That prep is going to make for a hull to be proud of later.

Re: Timid but determined Glasstream restoration

sprintst,
Thanks for the kind words.
I went back tonight and read about 30 pages of oop's thread. I really didn't want to go that far, but I can't get myself to do it part way. I will make sure it is right when it's done.
Thanks again
Bob

looking good bob, that sanding can be a pain but will be worth it in the end.

Yes it does!!!

Looking good Bob- Back to the last page- Yes, stop sanding before you get to the foam

Re: Timid but determined Glasstream restoration

Bob, Not sure about boat bottums. But as you know, when finishing wood the finish is done when you stop. The more work you put into it the better it will look. Knowing what I do about you, maybe mine will get splashed first. After all I only have 1 or 2 full years to go.

You boat looks like my plan to live forever. "SO FAR SO GOOD!"

Take your time, take it easy, and enjoy it.

Re: Timid but determined Glasstream restoration

Hello all,
Thanks tinkeringwackyone, micks110, and CLAYAROBINSON, I know me too, and that's what scares me.
I do have a question for all the great folks on here. I was rereading opp's thread, like I said in an earlier post, and I noticed that he removed all his gel with a grinder then spent a lot of time fairing out the hull. My method is to remove the gel while smoothing out the hull at the same time. Should reduce the fairing time in the end.
Anyone have any thoughts on my madness?
I would appreciate any comments.
Bob

Yes, you are MAD!!! But aren't we all???
I guess I am a fair weather friend on the fairing, as I have never tackled (and reading this not sure I EVER want too! )
I do know 100% that whatever way and whatever you do, It will look stellar!

Thanks Kev,
Yep, I know I'm nut's but I can live with it.
Take care

Re: Timid but determined Glasstream restoration

HOWDY!
Cool build! Your thread was referenced in another thread, so I spent some time this morning reading it. Nice work.
I'm going to borrow your plastic bag idea for the pour in foam. My wanna be engineer son suggested a similar idea last week, so plastic wrap it is. I noticed that you said you will 'seal' the foam if you have to trim it. And you'll use paint,is that correct? Did you just stand on the ply that you used to top the stringers? How big were your batches, and how much foam did that yield?
Wow, that's a lot of questions. Sorry. It's just that, mostly, all I need to do is pour foam and then I can screw the deck down and glass over it. And then my wife can pave her parking spot back and hopefully the city will back off me a bit!

Re: Timid but determined Glasstream restoration

JAFO1,
Glad you stopped in.
To answer your questions, Yes, After I poured the foam I put the board down and stood on it. I left the one end open to prevent generating excessive pressure. I kept the pours rather small to prevent it foam coming out the open end. I mixed about a quart at a time. Paint pail liners work great and after the foam cured in them you can peel it out and use it over and over. One thing to remember is to wrap the board in plastic to keep the foam from sticking to it. As for the amount of foam it will yield it depends on the density of the foam you use and the temp when you pour. It will grow to about 5 to 10 times the original volume.
Any area that I cut or broke the skin of the foam I sealed with paint.
I think I got them all.
Hope this helps
Bob

Thanks for the reply. Yes Bob, I think you got 'em all!
BTW, I got 2lb foam. In my research, I couldn't figure out if heavy foams were more buoyant, or worth the extra money. All I could figure out was that they weighed more per square foot. I didn't want the added weight.

Re: Timid but determined Glasstream restoration

hey Bob, what kind of paint did you use to seal the foam? Interestingly I just wrote a specification on repairing a foamed roof for a project....I called one of the supplier for info and he started "explaining" the urethane foam to me....I just laughed! Most of the roof top coats are elastomeric acrylic. There are also some buttle rubber products and some silicon also...but i'm guessing an oil based paint would work fine for boats. I notice they didn't recommend the elastomeric on roofs with standing water since it was water based. Basically all the top coats are designed to protect the foam from UV and water in areas where the "skin" is ruptured.

Re: Timid but determined Glasstream restoration

Hello arch,
Ell, I just used an oil based enamel.
It's kinda funny, When I was doing the testing last year I sealed some of the foam with a simple water base glue and after it dried I submerged it in water for two weeks and it did not absorb any water. I would still use the paint as I did.
Take care.
Bob

Re: Timid but determined Glasstream restoration

Bob, don't see a problem with the way you plan on dealing with the gel coat.

Having no practical experience my self, but from what I have read the only thing you need is good prep. Don't want any failure in the bond that is exposed when you sand. I don't know about resin but in metal manufacturing we avoid failure with platting/laminating after grind (i.e. sanding) by avoiding flaring materials. Not sure about this in boats because it would seam that flaring would give you a larger exposed joint line that may distribute any forces over a greater area. Also, abrupt striaght edges create stress risers.

I have been accused of over thinking things, so you may want to ignore this post.

P.S. Have I confused you yet? I have confused myself!

Re: Timid but determined Glasstream restoration

CLAYAROBINSON,
Thanks for the input.
Being and engineer by trade, over thinking isn't a problem.
Over researching is. I tend to research and look at a problem or project from as many angles as possible before starting.
Actually what I have read, in glass, sharp edges are not good. The more bevel the more surface area you have to bond to.
Thanks again
Bob
