Did you use chopped mat? If you did, I hate to say this, but you have no strength in your patch. The reason for this is Epoxy does not dissolve the binders that hold the mat together. All it does is absorb the epoxy creating bulk with nothing else. With the Double Axis glass with the mat on the back side, the mat is sewn into the glass and there are no binders to dissolve. Hence a strong patch. If you didn't then it will work.

The way you filled the void is fine, it's just a little resin heavy. When you put on your full sheets, that will make it very strong and have good adhesion. When applying resin/epoxy, you want the resin to be equal in weight to the glass you are using. You want the glass to be just wet, not soaked. When it goes almost clear, you have the right amount. Try to take the excess off before you install the patch. When I do a small patch like that, I use a chip brush. Paint a little on and watch it get soaked up. Move the piece to the project, and use the same brush to push it into position.

Overall, you are doing great. Keep it up and the porn as well. Loving this.......

Aquasport commodore yeah I used chopped strand first to build it up. I went back and sanded it down a little and put on some 1708. Just in that area. In the other spots I just used 1708 and epoxy. I am using a 2" chip brush to wet it out. I didn't use so much epoxy this time. So hopefully it came out better. Posting pictures for you guys to critique. If am doing something wrong or right let me have it. Not afraid of criticism!!!!

In the first 2 pics is where I sand it down to get to some glass and then laid some 1708 down. I did grind down more before laying on new glass.

That looks good. Just touch up the sharp edges on your stack to make the transition smooth for when you put the full sheets of glass on. Also don't forget to smooth over the hull sides as well. The starboard side where the core was tabbed in is still rough and has stringers sticking out. That won't help with bonding. You want all transitions to be smooth to keep air pockets/bubbles from forming where it lifts during out gassing.

This may help with how much to mix when you are ready to wet out...

Ripped it off from Ken Hankisons book, "Fiberglass boatbuilding for Amateurs ".

http://www.boatdesign.net/forums/attach ... -chart.jpg

Another great resource is the Geougeon Brothers book on Boat Construction available from about everywhere..

Well i did a little more work to the boat today. I have decided to add some wings to my transom, so i added to my existing template. Just need to be worked on a little to make sure everything is lined up and good. don't want one side higher than the other.
572
I also cut the top layer of my deck off on the back portion. As i need to get access to my stringers for my transom replacement. So it was suggested at least 18" of stringers to come out for the lay up. Well i knew the wood under the sole was bad. And since i had done a deck injection it felt a little more solid. Well this is what it looked like underneath the skin!!
573
574
575

So now it looks like i may be doing a whole new deck and raising it up. That way i can raise my scupper drains. I will be using nida core for the new sole. Between the coosa transom and nida core deck. The boat should come up out of the water some after removing all the rotted wood. This will also give me a chance to look at my foam in the stringers and under the floor.

So I decided to clean up the core from the bottom layer of skin. I need to get it clear so I can cut the layer of glass so I can access my stringers. The core was made up of pieces of 15/32" c c plugged exterior plywood. The pieces were about 6" x 12". There were also some squares that were as small as 2"x2". So it looks like it was just pieces together with scraps. I also figured that it got rotted out over time from water seeping in they the screws to hold down the cooler helm seat. I will get it cut up tomorrow to get to my stringers and get a look at my foam outside the stringers. Hope to get this done before I leave for sea!

I also called the fiberglass shops here in Norfolk. I was quoted $64 for a 4' x 8' piece of 3/4" nida core honeycomb. This is the only place around I could find nida core. So I will pick up 2 sheets soon. Hopefully this will be enough!

I would do away with that bottom glass. Since the wood was rotted where you cut to, I would be the rot fungus has migrated towards the bow (might not be bad yet, but it is there in microscopic and will grow) and you will have bonding issues (air pockets, left over wood, mold, etc, etc) the new core to the old skin. Not worth the headache to skimp here when there is no need. 1 layer of 1708 on the bottom and 2 on top. Call it done.

What you can do it make a ledge for the deck to sit on. Take some 4"pvc pipe cut in 4-6" slices, slice it and use them for clamps. Make a layer of glass say 6"x4" 6 layers thick and let it kick. Once hard, cut into rectangles and cover 1/2 of one side with epoxy and use the pvc clamps to hold in place. Once cured, you have a ledge to rest the new decking on. Do the same for the sides as well. As for the price that is about right. And I think it would take you 2-3 sheets to do your entire deck. Also I bet there is rot issues where the console is attached to the deck as well. Especially towards the bow part and also the tank lid.

Well I got the bottom layer of glass of the back portion of the deck that I cut up. From my observation the foam on the outside of the stringers is dry. I poked a hole in it and noticed no water at the bottom and no water when I squeezed a piece of foam I took out. Some spots of the foam are darker than others but it was all dry. I even put a vacuum hose to it for about a minute or so and no water came up to the top. So i think we are safe there. So do you think I should drill a hole in the stringers to test them for water? Or just wait since I am going to cut back about 16-18 inches to tab in my new transom. Also that blue stuff on top of the stringers is thick and hard!!

Notice the bulkhead in there? I haven't seen that in any other pictures of 170's being rebuilt! It is filled with foam and I noticed what looked like a mouse best. Well after closer examination it has a snake skin in there!! Zoom in on the picture and you can see it.

Yeah that core bond is thick and it was just as thick on the transom!!! No wonder I had a hell of a time removing the inner transom skin from the core. Yeah that is a good question how it got in there. I know there was a gap between the floor and the bulk head. But still how did the snake get in the boat and under the deck!
