Re: Floor fiberglass help.

Mix up about 3/4 of a quart at a time. Don't want it to set up on ya and loose it. Depends on how big your gaps are and how big of a fillet and cove you make. For the Whole deck prolly about a gallon.

Re: Floor fiberglass help.

I'm going to glass in the T piece now! When mixing the PB, do I need to add hardener for the amount of resin, or the amount of RESIN + Cabosil, or the total volume of teh PB?

Great, Just in time wood. So we just layed PB around the T piece in the front! Hooray! How long should we wait before laying the 1708?? Do we have to sand down the high points in the PB that tacked up on the sole itself? I want to have this in tonight!!

Re: Floor fiberglass help.

30 minutes and you should be able to sand and smooth and lay the 1708

Well, that SUCKED. We got the T piece in but KEPT GETTING BUBBLES. I used a squee jee + a roller and it was still hard. I'm going to have some grinding to do tomorrow... the resin got all over me and burns like crazy.. Only two thirds left to go :mad:

When I grind out the air bubbles, I fill them wth PB, right?

Grind out the bubbles and cut some small pieces of csm or biax to fit the hole then a piece to extend 4" over the hole....after it cures you can sand /feather the edges smooth.

Re: Floor fiberglass help.

So it came out pretty well, I think. I know, in the future, I need to prep a little better. The sides had some gunk on them that casued a few bubbles, but overall, it was pretty flat. How can I tell the difference between an air bubble and just a blemish?

Re: Floor fiberglass help.

I just drilled my drain holes in the stringers and gas tank housing,, filled them with PVC, sealed with PB. Wrestled in my new fuel fill hose... all 10 feet of it..
I have to deal with this gas tank business before I can lay the secodn section of the floor and glass that in.. I might try my hand at sewing today while I wait for the tank to pressure test :eek:

Re: Floor fiberglass help.

i'm a terrible seamst-er... I definitely need a bigger machine, this one can't take the 4 layers of vinyl. I'm also probably going to need more vinyl. I only ordered 3 yrds.. I need to do the whole bow and two back cushions. I ahve enough for piping, but I also need a piping foot.. freehanding it is, well, tough.

Re: Floor fiberglass help.

Use a zipper foot for piping. It makes it easy.

Re: Floor fiberglass help.

To be honest, IDK if this machine even has one available.. it's a total POS. unless they're universal? my girlfriend has a fancy singer one so I might have to get her to do some sewing!

Re: Floor fiberglass help.

They are universal. You can buy em on ebay for less than $10 bucks. I did all my upholstery that you see on my resto with a $35 Craigslist machine that was 50 years old. I've got an industrial one now but you can do it with an old POS machine just gotta get the tension right. Don't give up. Just go out to Youtube and watch some videos on how to sew upholstery and keep practicing. You'll get the hang of it.

Re: Floor fiberglass help.

Floor is getting glassed in and a coat of gelcoat today if all goes according to plan!! will update you guys with pics.. panning on working from 3-?? We want to fill the gas tank before putting it in for good. Hopefully all will go well. ANYONE have tips on rolling/squeejeeing in a gelcoat?I've watched friscoboaters gelcoat videos and that helped. Someone tell me if I have this: I mix up a batch at 2% with MEKP -- first coat gets no wax -- then I just roll it on like paint?

How long does it take to harden?

thanks again guys

Re: Floor fiberglass help.

Ran into some major issues today. The floor expanded and warped so we had to re shape and re coat parts of it and then set it and clamp it and do all types of crazy things. It's PL'd and PB'd in right now and we're waiting for it to dry then hopefully tonight we'll lay the top layer of glass and get at least half the floor in.. :mad:

Re: Floor fiberglass help.

Yesterday was just one of those days that really made me want to give up :mad: First, I went out to the garage to start putting in the fuel tank (with 6 gals of gas) I tested the sending unit and thank god, it still works. I go to grab my drill and see that it's covered in a bunch of white stuff. I have no idea what it is, but my drill is totally dead. None of the buttons would rotate, the torque selector was stuck. It was gone. So I ran to sears (I wanted specificallly a new craftsman 19.2 v drill just like the one I had) and picked up a new hammer drill for 80 bucks. I went back, put the tank in to fidn out I was out of OB oil. SO I had to run to K mart but all their oil was expired and the gas station "2 cycle oil" was for air cooled engines only. So I drove another 40 mins to wal mart an dpicked up a gallon of oil. ALl said and done, I ran the motor and it was dying in idle. I gave it a few low speed carb adjustments and I think I fixed it. Then It was time to "glass and gelcoat the floor" (that was my goal for yesterday. Howeve,r I got a late start with all the drill issues and so forth so I changed my goal to be just glass in the floor. I go to test fit section 2 of the floor and it doesn't fit and the wood warped. F*&^!! I trimmed teh wood downa nd it was just all messed up. I had 1/2" gaps and 1" overlaps and it was just a mess. An hour of measuring and jigsawing later I got it to fit, but it didn't fix the warp. I tried paddign the stringer with wood that I was going to glass on and leave there, but nothing helped except clamping the wood. So I PB'd the outsides, clamped and weighted the wood down the way I wanted it and waited for the PB to set... and waited... and waited. It didn't set at 130 AM so I threw in the towel and called it a night. I went out this AM first thing and it actually looks like it held up pretty well. I'm not steppign anywhere but in the ski locker and on the gunwales until I get it fully glassed in, hopefully tomorrow... and that first layer of gelcoat. It just really sucked having to re-do things that I thought were done.. cutting and measuring and precoating.. I think that the resin caused the wood to expand and warp. either way, it was just miserable. Here's a pic of the sole as it is right now, The deck plate was there just for measuring, it's not permanent yet. The front "T" piece is glassed in and strong :)

UH, WOAH!? we can upload pics directly from our computers now!! Cool, thanks Iboats :D
