Hey! I fixed my bike!

[CaptStash]

So...my Blue AC1 got tripped over when it was on my son's Kickr. Long and the short of it was a broken chainstay. All the quotes for a repair were around $500-$600, which is about what the frame is worth. In the meantime, I got smacked into by a commercial fishing boat in rowing shell, and had to get my carbon repair skills on anyway. After teh boat repairs came out well, I decided to have a go at the Blue.

I sanded it down pretty aggressively, then installed two layers of unidirectional carbon on each side of the chainstay, along with one layer on the top and bottom. I finished it with a signle layer of carbon weave. When it was done, the drive side stay was noticeably stiffer than the non-drive side, so I am pretty confident of the repair.

Not ready to hang out a shingle - but still pretty happy with this.

Very nice! How did you compact the carbon layers?

[kmla320]

well done!!!!

I didn't - and am not clear that it is necessary so long as the the carbon is fully wetted out with the epoxy. I squeegeed with my fingers (in gloves) and was pretty liberal with the goop. I did lots of sanding in between to ensure a smooth surface without voids to bond to.

Again...don't let the Adjudicator catch you doing crazy $hit like these....:p

Interesting. At least in theory, there is extra resin that adds weight but not much strength.

And how did you finish? When I apply the final weave, the edge doesn't blend in very well. Did you sand and clearcoat afterwards?

I made sure to make the edges of the carbon well overshoot the repair, then sanded and feathered followed by a clear coat of resin. Finally wet sanded with 220 & 600 and polishing compound. Smooth as a baby’s bottom.

That's impressive. How did you determine the drive side stay to be stiffer? Just manually flexing the stays?

I hope the boat turned out well.

Yes just manually flexing the chain stays.

Boat turned out quite well - that's what gave nme the confidence to attempt the bike repair (that and lots of fun on YouTube). The first generation Hudson singles have an inherent design flaw, so I I'll be doing the same repair on it on the other side this winter, then spray out the whole thing. It's a very old carbon boat, so it takes a bit of care and feeding. Still fast and stiff, so I'm good with it.

This got me to thinking:Adjudicator - a person who impartially decides or resolves a dispute or controversy.That doesn't sound like it's always such a bad thing...;)

Very impresssive!

And I am thinking you probably don't want to mess with her...

Post pix of the boat! I need to pick up a single again, sold my empacher a few years back

I'm still trying to figure out where a commercial fishing boat and a rowing shell would occupy the same stretch of water?? ;)

[Allcarbon]

Wow, I would never even considered undertaking carbon repair on my own, but it certainly looks like it can be learned if you know what you are doing.

The ship canal in Seattle. I was headed back towards Lake Union, and he was lining-up for the Ballard locks (heading for Alaska). I was on the right side of the channel, but doodoo happens. Luckily it was a warm morning andI know how to swim!😜
