Oops,
I got your PM?s but since then I had remembered that yesterday I bought an attachment for my 4 ? inch Black and Decker grinder so it is a sander also. I know it?s not a 8 inch but I thought I would give it a try just a minute ago. In a very short time I got one side done on the boat, all the gel coat off. Almost too easy compared to the grinder.

The results as compared to the grinder I was using yesterday.

With the grinder I was leaving divots not moguls but still small bumpy spots. With this sander I have achieved 2 times less and 2 times smaller imperfections in the sand job. (I?ll post photos tonight). I went over the spots from the grinder and in short order they were a heck of a lot smoother with minimum removal of material.

Now for the arrogant part? With all of the years of sanding wood I am above average with a sander and this looks like it may work out pretty well ( the 4 ? inch sander).

In looking at the bottom of the boat I am sure I will need to add a few layers of material and FG resin and it looks like I will be able to end with a pretty nice finish on it. Not like you would see on a new boat but I think it will look good to the general public and not have so many noticeable bumps on it. Even with such a small cutting surface making contact with the boat it is coming out pretty flat. We?ll see as I go.

I had one of my hard drives crash in my computer (I have 6) so I could not post photos last night.
I was only able to work 2 or 3 hours yesterday before I had to stop, to sore. But I got a lot of the boat bottom done and today I will do the rest then smooth it out some more.
Here is what it looks like right now.

I'll get the rest of the bottom done today.

I think I'm only going to take off the jell coat to just around and up the sides of the boat. (like seen in on the back of the boat but maybe a little more) Then I will sand the rest smooth and repaint or jell that with the rest when i get there.

I have a question pertaining to this statement by Oops.

if you grind....you will have minor grinding imperfections in the glass.....even after re glassing....these will show up to some extent.

When I did use the grinder I did leave little divots but I?ll be able to smooth them out a fare amount.
My boat hull is only a total of about 3/32 thick over all. Not even 1/8 thick. (well darn close to these sizes, give or take some)

My question is this?

Oops are you thinking my boat hull is thicker and there for I?m able to get BIG & DEEP divots that are pretty deep? Then able projecting up thru the new FG layers when I lay them?
I believe these davits that I will have left behind will be around 1/64 to 1/32 deep. Will that project up thru the new layers of FG?

Well here is what I got done today. I sanded down the sides about all I feel I need to go. I plane on laying my FG to the sand line.
Then When it?s time to paint or gel coat I?ll put a strip around the joint line. I think it will look pretty good, I may try to make the strip about even with the water level line. Not real sure on all of that though just thinking.

Been working! I keep thinking that I?ll clean tomorrow but then I get suited up and think why? I?m going to sand more anyway I think tomorrow I may clean up though because I should be done sanding the gel coat off now.

I may even be woring on my first FG patch.

Re: I would like to introduce myself, and talk about my rebuild.

inless you are a absolute magician with the grinder.....the divots are a lot deeper than 1/64 th or 32nd.

more like 16th......put a blade of a knife on the hull.....youll see lots of daylight between the blade and the hull.....yes these will project thru the new layer of glass to some extent....you cant just add more resin....that will be weak......so sand or grind flat.....it will save you a lot of work at a later stage.

your hull is a minimum of 1/4 inch thick.



and as far as the dust on the floor.......yup....thats what it looks like

Re: I would like to introduce myself, and talk about my rebuild.

A few days ago I switched over to the sander and had been using it from about post #86 on. Nope, that that good with the grinder and I?m very sure that if I put a putty knife edge up to the parts of the boat that was done with the grinder you will see day light through it.

I have not gone over the parts yet that was done with the grinder the first few days but I?m going to. I wanted to get the rest of the gel off before I go back and work on getting it smoother.

When I was speaking of having it on the smoother side I guess I should have clarified that was since I have switched to using the sander. Today was the last day of sanding off the gel coat and tomorrow I?m going to go over the whole bottom again and work on getting it as flat as I can without going thru. I may even measure the thickness so I can speak more aerate.

The makeup of the bottom looks like it is the thick layer of gel coat then a thin resin, then a woven mat, then a thin layer of resin now you?re on the inside of the boat. In my sanding I can?t see another layer of material but that may be because I just can?t see it from my poor eye sight.

But I know that you can push on the bottom (in a larger flat area) with little force and be able to flex the hull very easy. This hull is not at all like I remembered my father?s old deep-v was. I seem to remember that on his boat the hull seemed to be two times thinker at least. This one seems like it is just a thin shell compared to it. While sanding I was stopping just as soon as the white disappeared and stopped right there, taking as little material off as I could.

As for the white stuff on the floor, well really I had a strange guy visit from Columbia visit a few days ago and he spilled a bunch of stuff all over the place from a duffle bag he was carrying. He said he was working for a company with a strange name like Osargeas Cartel. I think he had to do with selling car parts or something like that.

The grinding (or sanding now really) is not to bad now that I have the mask, earphones, gloves and paper suit to ware. It?s just that in a short time the stretching out of my arms starts to hurt my back pretty bad and I have to stop after a short time. But it is sort of fun watching the white disappear when I run the sander over it. It comes off in no time really and at least it?s not like trying to sand off polyurethane that plugs up the sand paper and melts into a goo.

I think in a little time of sanding over the bottom again I will be able to get it as smooth as I can. Not ever having done fiberglass before I?m not sure how smooth it has to be without projecting bumps thru. With what Oops says in his last post about how much it will project thru I?m about sure I will have some no matter how well I sand. I just don?t think I have the material thickness to get it like a new boat. In a way I wonder if someone has already sanded this boat in the last thirty years already.

I?m thinking I?ll be happy with what I come out with because if I do my best that I can well??. I just can?t do any better and that is all I ask of myself.

And when I?m scooting across the water at a blistering speed of 8 miles an hour I think I will be going by so fast (really in a blink of an eye) no one will be able to see it anyway.

Now, if I get gutsy enough to open up the 1969 18HP Fastwin and my boat flips like a hydrofoil can from the extreme wind getting up under the boat then someone may be able to see that it was my first fiberglass job.

I?ll just have to reframe from the temptation in doing that.

Re: I would like to introduce myself, and talk about my rebuild.

rick there is another solution.......

if you "sand the hull smooth" what you are doing is knocking down the highs and leaving the allready thin lows of the hull.

so ......rather than sanding.......
after your done taking off the gell, clean well with aceitone, mix up a batch of medium thick peanut butter with milled fibers in it. then with a putty knife...apply that stuff like you would apply drywall mud.
then you will be adding a layer of fresh glass to a smooth hull.

Thanks that does sound like a good way to proceed, adding thickness can?t hurt. A few days ago I went out to try to find the ingredients for your Peanut Butter (patent pending) but we don?t have a local store that carries it. I may need to venture into Tacoma. I?ll just have to make sure my life insurance is paid up to date. Tacoma is a dirty and unsavory place to go to.

I sort of eluded to in a sort of funny way that my boat is not going to be the best thing going. It?s sort of my learning boat and will really be used for fishing. I want to make it as nice as I can (with my budget) but really I don?t mind what imperfections I am left with. It is fun working on the boat and learning as I go it also gives me something productive to do that helps keep me limber.

I?m already fight the onset of MBS! I have passed up 4 free boats already because I know I don?t have the money to get them going. One was a 22 foot deep-V with no motor (outboard) and no trailer, that was all that was wrong with it. Living here near Seattle give a person a great opportunity to pick up a free boat being so close the water AND being so close to all the rich people that work for Microsoft.

Well I got the garage cleaned out best as I could today. I raised the boat shell up and put backer on the outside of the boat in prep for patching it from the inside tomorrow.

I had to turn on the heat to get it up to temp before I fiberglass.

Oops I have located the ingredients for Peanut Butter but not locally I have to order it from Amazon dot com. I?ll have that next week and can do the buildup then when I get it.

Rick did you look at US Composities .com they have it also and at a better price ?? John

Re: I would like to introduce myself, and talk about my rebuild.

John not yet but I will. I have not made the order yet because I'm still looking up and reading about what things do what as far as fillers go.

I did put some information into the thread http://forums.iboats.com/showthread.php?p=1911369#post1911369
that I have found so far.

Now i see there are differnt fillers for Peanut Butter as for its intended use.

ie small cracks, joints or leveling like Oops told me about doing to my hull. I think I'll need to buy at least two types of fillers.

You may want to read the info I posted. (but you may already know it) i just found it interesting like everything new that I learn. I have to study it to death!

Re: I would like to introduce myself, and talk about my rebuild.

Here's a good write up and more info on epoxy resins and such.
I bought my stuff from John Greer in San Diego. Good price and great products and on eBay also.

 

[oops!]

Re: I would like to introduce myself, and talk about my rebuild.

rick....if the thing isnt about pretty for you...cool......but you do want it safe !

so just forget about filling the lows...and do a hull wrap !


then sand it some what smooth....and paint it with some cheap rustolium......done !

if you just wanna go fishin.......just take the csm santa brought you and wrap the hull twice.....give er a few more layers on the keel and done.

 

[jcsftwre]

Re: I would like to introduce myself, and talk about my rebuild.

Oops, here is what I?m thinking for my game plan. A lot is what you already told me to do. I defiantly want it safe and feel it is to thin right now.

By the way Santa sent me 1OZ CSM (for the record)

1st I?m going to patch the holes from the inside. To give me the form I need to add back on.

Then flip it over and work on the outside of the hull.
Fill in the high and low spots with Peanut Butter to smooth it out.
2nd then do over the whole bottom.
2 layers of CSM
1 layer of woven
1 layers of CSM
1 layer of woven

Then coat over that I don?t know if it will be gel or paint I?ll ask when I get that far. For paint I will be doing rustolium most likely.

Then I?ll flip it again and on the inside here is what I?m wanting to do.
1st Stingers put in and wrapped in FG CSM to hold fast.
2nd 1 or 2 layers of CSM over the whole bottom
Then one layer of Woven
Then one more layer of CSM over that.

Then the floor (deck) covered both side with FG SCM.

I think that will give it a solid bottom.


I say that I know it won?t be fancy or perfect just because I know that I don?t have that good of skill level to make it look new. But believe me I?m going to do my very best to try to make it look that way. I guess I?m just trying to be realistic with myself about how good I can do it. So that way if it comes out better I really will be happy.

I?m taking all of the advice I get from my thread and try to research the information then try to make it fit with my budget and in the order of what materials that I have at the time to keep moving forward.

First and foremost I do want it safe and that is why I ask what I need to do. I try not to ask to many questions so I don?t waste other peoples time.

That may be why I seem to be doing things out of order. I may ask one thing because I think that is what I need to do next. When I get the answer..... Then I realize from the answer that I need to re work my plan because I did not know the new information a few days ago.

Know what I mean?

I take all to heart what information I get, I want one day to post my photo of the boat I built with Iboats help and have a nice looking and safe boat.


P.S. Please don?t take what I said in my posts a few days ago as me trying to be sarcastic. When I spoke about ripping across the water. It is my sort of humor, Sometime I will say things like ?It looks good from a 60 miles an hour roll!? Meaning that when I drive by no one will see the dents in my truck. Or I?ll say ?Hey! It looks good from my house!? meaning the same thing. My sort of humor. I did forget to talk about the big smile I will have on my face because I know what work I have done on my boat and I know it will take me to that next fishing whole.
