    Wow, did you cut that by hand? What's the thickness of the carbon sheet (I wasn't sure if you made the sheet yourself or bought it)?

    So you're saying you made the sheet of carbon yourself, by laying 6 layers of prepreg fiber together? If so, you did a great job, the surface finish looks like professionally made carbon. It would be great to see some detail on that part of the process, if you made it yourself, or if I misunderstand and you actually bought the 2mm thick plate, I'd love to see what the specs/source were for that material.

    Thanks for sharing.

    No no no the sheet was bought but it has 6 layers . Srry didn't mean to confuse you .
    I do make my own carbon fibre sheets and kevlar/twaron sheets with simple wet layering but the finish is nothing like this . I also make my own carbon parts using wooden moulds I make . I have to use clear coat in order for it to have a high gloss finish which unfortunately adds weight .

    This is where the sheet is from :

    Can you quantify what you qualify as "mild use"? Like once a week/month/year?

    I was thinking the same thing. I remember once, during a drunken bike maintenance session years ago, that I had misrouted the chain in my rear derailleur. After only a few spins by hand (while lubing the chain) I noticed the goof up, but it had already gauged the carbon arm.

    While the chain is working in concert with the chainring in your case (so not exactly like my stupid example), I'd still expect a lot of wear. (?)

    About three times a month and only for around an hour . TBH this really would be for racing applications only .

    Never drink and ride !!!

    No you're right it will wear far more than an alloy ring due to metal being harder but you can still get a few hundred miles out of the chainring .
    Stephen from FibreLyte told me his racers put lots of oil on the chain and always clean the chainring after each ride .
