HI All
I have just completed by first carbon wrap using a starter kit. Its a c/f tube for carrying fishing rods. I have wet laid it and although its pretty rough and ready its as you would expect for a first attempt. I wrapped the c/f around a plastic tube which I coated with PVA release agent from EC. Just no way this is coming off though! Any tricks or hacks would be really appreciated to (1) get the c/f tube off (2) better ways to do next time. Thanks all

I found Easycomposite video very helpful for making carbon fibre rods

Thank you for that. After some brute force it came off - unfortunately half the length (as had to cut it) as I wanted but thats OK as first time. Wrap and strength are good so thats a positive.
