Bodge up coming up - will it work though?

To get me back in the water for a month or so until I can get the bits I need to fix my holy toob, I'm concocting a bodge up.

Here it is as it looks at the moment, perhaps difficult to see but major fabric structural failure in progress along the middle of the damaged area and out to both sides. The cone on the starboard side I think is heading the same way and the whole problem is due to the seams on the cone end flexing and chafing. Which at the risk of receiving another email titled "Without prejudice" could attract some negative comment on the design front but I won't go down that road again....



What I'm thinking is wallop a patch over the top of that (again) good enough to last for a month or six weeks till I can get the whole new tube ends here to try and do a proper repair job, which will involve cutting the ends off the tubes an inch or two in front of the original seam and sticking whole new ends in. Which I am not too confident about doing myself ... but not much option really!

Back to this question. I could do one of two things, clean up the area where the orange top layer has peeled off and stick a small patch on approximately following the outline of the yellow line, which would cover the area where it is actually leaking. Or put a much bigger patch on covering the area outlined by the blue line.



Pros and cons to me seem to be:

Yellow - can be tucked down behind the seam so less of a leading edge, but will the glue stick to the bare fabric now the orange stuff has gone?? May be weaker.

Blue - May be stronger, but leaves a forward facing leading edge that may pick up in the flow of water. May also leak along the seams.

Both are a bodge, but either only need to get me through to maybe early December just so I don't miss the first half of the summer. All the affected area covered by either patch will be in the bin anyway once I get on to the proper repair job, so no real problems from that side.

Any thoughts? Yellow or blue?

cheers

Stephen

Don't know how many ribs there are in the FI but put it this way, if you pull this off and manage to get new end cones fitted you would become the local expert sitting comfortably in my arm chair I suggest you go for it.

Why either or?
I think I'd go for both. See no reason why the smaller one should not stick, but another patch on top would give me added confidence.

Wasn't an area of expertise I was hoping to become involved in

As Neil says I suppose I could do both hadn't really considered that!

Is the glue likely to stick to the exposed fabric at all though? It feels quite "slippery"

yellow?

I'm looking at your picture and thinking if it was me I would go yellow as I think it could be a problem getting a really good flat lay accros the exsiting seam cover.My only concern was whether the existing fabric will take the glue ok? If not or if you doubt it ,it has to be blue.Make sure the whole lots clean !!!!
good luck, if you pull it off You deserve a pat on the back for perserverance

A Friend of mine had a similar problem to yours and instead of of your proposed "blue" patch we put a new wide strip " width of Blue patch" around the entire tube to re enforce the join and to cover other fabric that looked like it might also fail, that was in 2002 and its still holding fine :-)

Haven't got enough repair fabric available right now to do that though, and it only needs to hold for a few weeks anyway as a bigger job is needed to do it properly otherwise I'll always be waiting for it to go wrong again....

Cheers for the comments, hope the weather is fine on the weekend and I will put my bodging hat on

Stephen,

Just a little tip that has worked for me well in the past. The leading edge of that repair will be having masses of water pushed against it when on the move. Am I correct.

To stop the water working its way under the patch and lifting it, I've just seen what water can do with large patches put on a tube on my mates RIBCRAFT, My tip is to run a ridge of Super Glue Gel along the front of the ridge just in front of the repair. It does work.

I've a feelling your going to tell me though that you can't get the stuff down there.

Best of luck.

Nick R.
