This is an easy method to fix a carbon boom using basic tools. Another great way to make longer use of your gear. For more watch the other episodes: • Pimp my Board - How to...
So, I did the same thing to a boom a few years ago. The difference was that I used a preformed carbon tube instead of the wood rod, and I bought carbon sock material instead of fabric. My repair was more expensive, but maybe lighter/stronger? Also, I have seen people use heat shrink tubing instead of the tape. It leaves a nice clean surface with minimal sanding.
Great repair, the only thing i would consider is when the wood is not fully submurged in epoxy it could suck up water and expeand and in the worst case damage the boom from the inside.
Nice. I wonder if a hollow plastic tube could be used in place of the wood dowel to minimize weight. At 3.45, I think the word you are looking for is 'tail-piece'
Thanks for 3:45 ;-) Hm don't know about the plastic tube - might work just as good, but might be more difficult to handcraft, since the turning-over-trick doesn't work anymore. Also the weight difference ist small I think. If you try it, let me know!
Hi, nice tutorial thanks for sharing. Can you tell me what kind of carbon fiber have you used? 100-400g/m2? Which one is the best? How thick should be carbon ‘pipe’? I plan to repair and reinforce my aluminium broken boom.
Hi! This might nit work with an aluminium pipe. Regarding the wall thickness: on a carbon boom it only needs to be as thick as the original diameter. On a aluminium boom i guess it should be the original thickness plus 1 mm. The cloth type (100 or 400g/m2 doesnt matter as long as u manage to wrap it around the tube. Good luck!
Puuh theoretically its possible, but very difficult.I would try to stick a stick or similar (maybe the extension part), that you laminate on to and that you can pull out after the lamination. Release agent will not be enough, i think. Maybe wrap ut with foil. Then laminate a bit thicker (more than the boom diameter)
Sorry, but +45/-45 is the wrong orientation for the fibers. The main loading comes from bending and this means 0° (along boom axis). Better use carbon flex hose or a combination of 0° non-crimped fabric together with your 45° fabric. The best would be a +20°/-20° non-crimped fabric made of two thin layers wound in your style.
