Nice method! I made a carbon fiber spinnaker pole for my 15-footer by rolling it on a PVC tube. Didn't use the tape on the table to be able to stretch it and got lots of wrinkles in it. The plan was to just wrap it in plastic and roll it until all wrinkles were gone, but that didn't work. A bit of sanding, filler and another wrap saved it, but nice to see you can get much better results with a smart method. Keeping the mold tube inside really simplifies the process and doesn't add a lot of weight, so unless you aim for the ultimate weight saving this is a good way to do it. I've seen that you can use shrink tape for the final wrapping. You heat it up and the tape will shrink and create a really tight wrap. I'll try that next time.
Shrink tape is a great idea. I may try that some day. On my first attempt I used saran wrap to wrap it at the end, but it didn't work well at all. That's why I went to tape for the second try.
Thank you for this video. It is funny to ear about Yann Quenet from California ! He lives 60 kms from my home and he draw me a plan for a 2.90 meter boat.🙂
Nicely done. Working with wetted out carbon fiber is like wrestling a greased eel. I made a sprit boom for a small sail and it came out so bad it looked like I painted a stick from the woods. It is nicknamed "Lumpy". You did much better.
On the first bar which you showed, you might not have liked the uneven surface, but considering how slick carbon fiber tubes are, the nobbly and uneven surface would provide an incredible easy-to-grip surface, fitting easily in your hands, which is what is needed when sailing.
9th comment on OCSS February mini episodes! I've been watching your subscriber count move steadily upwards since you started the mini-sodes, I think it's working Capt. Perry!
Thank you. Sub count is moving up at the same speed as always, but I can still be happy for that. Better than the other direction. More total views for the month due to all the extra videos, though, so that's nice.
I could definitely make a tiller this way. I actually used the nicest 2/3rds of that first tube as the port side handrail, and the rest will be part of a swim step on the transom.
I am wondering why you did not use carbon fiber sleeves for the handrail. They are manufactured in a variety of diameters and can be formed and fit to the PVC mold you used. Down the road, you may wish to check that out as a possible fabrication option.
I've used sleeves to beef up windsurfer carbon masts for other boats and it worked well. But here, Capt. Perry got 5 layers at one go. With sleeves, he would have had to laminate a layer at a time, carefully sanding (carbon fiber dust is very bad for you) between each application. I think sleeves are better for bigger jobs.
I have to agree with you. That may have been what added the few wrinkles to the finished product. Since he started at one end wrapping in a spiral pattern, it likely pushed slack in the carbon fiber wrap as he worked it along the length -- from tight side to loose side. Wrapping the peel ply in the same fashion as the carbon fiber would more evenly disperse the pressure.
It's far easier to get even pressure this way, the peelply will hold itself as one wraps it up and it won't unravel. Also, as pressure is force divided by surface, less strength is needed to compress the CF tightly as we only wrap a small surface at a time.
Try it and you will understand. The first failed attempt was made worse by doing it how you suggest. It's much harder to get a tight wrap if you don't use a long thin strip. I've made a couple now with the way shown and the results are great.
For a lot of layup work, vacuum bagging is overkill. The peel ply and duct tape serve the same purpose as vacuum bagging by consolidating the layers and forcing out air and excess resin.
You might have got less wrinkles if you didn't wrap with duct tape, i'm guessing the duct tape is to make it easier to deal with while curing? could you just hang it with some wire (coat hanger) tucked into the ends of the pvc? Or is the purpose of the duct tape to also apply some compression and squeeze out some epoxy (poor mans vacuum bagging?)
Great technique for fabricating carbon tubes. Very well done!
Glad you liked it!

😀 I'm a fan
I like Yann's designs. He's a clever man.
What a difference between the prototype ❌ and the real thing ✔. You obviously don't let problems beat you and you like to learn from your mistakes.

Yes exactly! It's as slippery as an eel in an oil slick, haha. You should have another try and remake that pole.

I love the guy by the water heater. It adds just a bit of the flare of a pirate.🏴☠️
Thanks, that's Steve. He hangs out down here until Halloween when he gets to go upstairs.
good video , thanks

Nice to see more work.
Making tubes is difficult
It's true, it is quite tricky I learned.
Very useful! Carbon fiber poles are so expensive.
I'm not sure what your plans are for the tiller, but the first tube could be used as an emergency tiller perhaps.

👍👍👍
I’ve been wanting to try some carbon fiber
It's pretty cool. A bit slippery to work with but not too different than fiberglass.
Would vacuum bagging give you better results ?
Could be, but I don't have the equipment and decided to complete this build without it.
The You Tube channel Easy Composites Ltd is informative relative to carbon fiber construction.
Can I ask what type epoxy you used any specific ratio. Thank u
US Composites at a 3:1 ratio.

He got a great result with the carbon cloth.
I didn't use sleeves because it would be harder to get them tight. By rolling it I can tighten it up like rolling a cigar.

Why use a thin strip of peelply? And not use the same width as the bar? Not getting that spiral.
I have to agree with you. That may have been what added the few wrinkles to the finished product.

@@j.saavedra1502agreed, just like Shayne does on Young Barnacles.
I don't have the equipment and I don't really feel it's necessary.

Or is the purpose of the duct tape to also apply some compression and squeeze out some epoxy (poor mans vacuum bagging?)
Yes it's poor man vacuum bagging. The end result was quite good. Everything will eventually get some fairing and painting anyway.
Maybe you don't want it super smooth?
Too many short videos, losing track of the big picture. Need a good overall review of the project.
Keep putting out the short videos. They're a great addition to your channel!
I like the regular updates, keep them coming please. 👍
