Jeffs 1988 BFN Rebuild

wow I gotta get me one of those!!

How did you peel the gelcoat off? Grinder? You did a nice job!

Is the tape 2,4,8 cloth or biax? US Composites does not sell a biax in the 2,4,8 sizes.
In Turbos thread it was listed" 2,4,8 biax 12"over the top".Is it cloth tape than 12" biax to cap it off?

And I found 1708 that is described as "soft" it wont go vertical but will lay flat. Sound ok?
Jeff

Is 1708 going to be strong enough for the floor (over foam?)
I also had to remove all the hull glass my plan was to run 50” wide down the center then 50” wide down each side overlapping in the bilge .I’m not sure I like the bilge overlap but..
And if I have read correctly biax too wrap the stringers and cloth to finish. Running 2” ,4”8” my question is do I run tis parallel with the stringer or do I cut small strips and drape over diagonally going one way then the next up and down the stringer?

I have never heard anything bad about RAKA, some people feel it is better to work with and has the same finished qualities.. the extra cost is not huge. I just orded another few hundred pounds of stuff from US composites so I guess I am not exactly a convert yet but I may try Raka at some point.

**Sorry for the thread jack**

I know most of the guys here use US composites to get their rebuild stuff but just for the sake of asking has anyone used or heard of Raka.com?

I was talking with one of the new guy's in the shop who is building a woody from scratch and suggested Raka instead of US. I'm just throwing this out there. Pete, Tim, Joe any of you guy's hear of them?

We braced our BFN at the chine right near the windshield, and again at the transom. We also blocked the keel in 2 or 3 places. Once supported, we brought the trailer up to the hull as a brace, though it didnt really hold much (if any) weight- it was there to prevent flexing. Id repost my picture, but Im not allowed!

I will let you post pictures or is it top secret squire stuff

Tim, Pete
What if any precautions did you take with the bottom of your hull while working on it? In your picture it looks close to the current state that mine is in. Is the 3 point stand still a viable solution when the hull is getting this “thin” it is very loose/flexible if that make any sense. I will be adding 2 more supports to the front under the windshield chine area, similar idea to what Greg did when he left it on the trailer.

Jeff,
You said the wood around the exhaust was OK but soft. I wouldn't take the chance on it and suggest you put new in. You're way into the hull anyway!!

I agree with Tim and it does look like you have some delam in the hull. Just as he mentioned, get the loose stuff up and replace it.

We removed all glass that was used to attach the original stringers. That was no small task. Lots of work with the grinder, as well as flat bars to get it to peel up. In a few sections, more came up than we intended- we got hull glass up unintentionally. Might have been poor lamination or overzealous desctruction... or maybe a bit of both. We were sure to replace the hull glass in these sections (and then some).

Stringers out, but glass still in:



All stringer glass out:



You can see where we took too much glass off in the foreground of the last picture, just to the right of the keel.

Id say youre into the hull glass now. If its coming up easy, then take it off and be sure to replace it. If you can get to a spot where it comes off pretty hard, then grind the transition smooth and leave it.

What would be the problm It was over sized laid the old stringers on the plank traced them out and cut.It was 18-20'long I think

Whys that Greg the ?..stand.I have a rachet strap going all the way around the transom.

Did you get my e-mail in regards to contact info.
Jeff

Luv that stand, but this concerns me a little...

Jeff, when you go to repairing the goof cut your repair plys in rounded rectangles or circles making sure each ply has about 1/2" overlap over the prior one. Make the first ply slightly larger than the damage. Lay the smallest down first when you are ready to install it and work your way up to the largest ply.

If you have corners in your plies they will have more of a tendancy to lift up and secondly more stress is concentrated on corners. Rounding your repairs distributes load stresses more evenly and they lay down nicely. Making each ply bigger than the other makes for a stronger repair as you have 3 layers of glass bonded to the hull instead of just "one" thick one.

A few more questions.My boat was over 50% gutted when I started and Im not sure what the floor was like.I just read the pumpkinpatch again and it sounds like 3/4 ply I like how Gregs turned out ,was that a factory reproduction or was all the ply of Gregs design? I did cut out under the dash forward and don t recall any ply floor.
