BBIII update

It seems like either way there is going to be a bump at the tape. For some reason it seems to make more sense to me to tape first and then sand the edge of the tape to knock the edge off and sheathe over that. I was most concerned about the tape causing problems with the process of doing the sheathing the hull.

I am only using one layer of cloth on the boat but I do like the idea of the seam down the center of the hull.
 
Yes, if you are only putting down one layer of sheathing... then yes you'll want to use tape. And you will have to fair (should fair, hell the boat is going to outlast you, may as well do a first rate job).

Most guys put down two layers of sheathing on the hull... and from my experience, I'd rather have two layers of sheathing on the hull, which negates the need for tape and it's smooth as hell and if you put the cloth in the middle with no cloth layover on one side of the hull or the other - your boat will aim true ...

Again, the beauty of free advice is that you don't have to take it.

Andrew,

I only used one full layer of cloth over top of the taped seams. I first taped the seams and sanded down the edges with an orbital sander. It blended well and when I placed the sheathing on top you can't see the transition or bump where the tape is.
 
I did the same thing Ryan... I had to fair the edge/ridge where the tape and sheathing met... It's not the end of the world and I'm pretty fussy... but there is a ridge for sure... I remember running a straight edge and there was a gap, which is now filled with epoxy/micro b's.

No worries, the boats all work.
 
Hey guys! I did the very same thing. I taped and then sanded the edges down to meet the wood with a nice taper. You can see that I even went a little too much in some spots when you look at the second photo in post #32.

Here is what I am banking on...when I lay the layer of glass and wet it out I will wait a few hours and add another layer of epoxy, then another a few hours later. With the build-up of the epoxy layers it should fill any small imperfections that I have at the tape. I don't think there will be too many areas that I need to worry about because when I was sanding the tape edges I kept running my hand along it to feel for any ridges. Once I sand the entire thing, if I find any areas that need fairing then I will use the micro b's.

I'm going to be using two separate sheets of glass and doing what Andrew said and placing the seam on the keel so that I don't have to worry about any other seams.

Thats my theory anyway...
 
Well the glass is on the hull. Took me about 2-2.5 hours to complete the entire wet out. I ended up not putting the seam on the keel like I planned. I got to thinking about it when I laid the glass out and thought it would be better to have more layers at the keel area. I overlapped the 8in tape on the keel about an inch or so.

I used a squeege to apply the epoxy for the initial wet out and I'm using a foam roller to fill the weave. I applied two coats yesterday and I am getting ready to go out today and do a light sanding before applying more epoxy with the foam roller. I'm looking to get it as smooth as Charlie's. I have a challenge in front of me for sure! Looking good Charlie!

Jim ,

Nice work !!!!! What are you using for material ? You are doing a hell of a job . Keep the picks coming

Thanks guys. It means a lot coming from a bunch of great guys such a yourselves.

Charlie - I really think that I was lucky. I did get some drips here and there on the concrete but I consider them garage character building.
"Hey what is all over your floor? I looks like someone spilled something."
"Nope - thats epoxy from my boat build."
"You built a boat??!! Cool!"
There is more to the conversation but I don't want to freak you guys out too much.

Dave - Not sure what materials you might be asking about but I'll go with what I used to sheath the hull. The fiberglass is 52in 6oz from US Composites and the epoxy is a 3:1 Medium hardner also from US Composites. I put 9in 8oz fiberglass tape (with a very tight weave) that my brother had left from his boat build along the chines and the keel. Let me know if there is anything else.
