    1.5mm carbon fibre rod

    hi all i am wanting to build a cage to go around my propeller (11x7) on an air boat i am thinking of making
    i was thinking of using 1.5mm carbon fiber rod as it is lighter than steel
    what i would like to know is will i be able to bend it into a 12 inch diameter hoop or will it just shatter at that size
    i have found a glue i can use (http://www.easycomposites.co.uk/#!/r...-adhesive.html )
    for gluing the ribs etc i just wasn't sure how far i could bend this stuff

    Its gonna snap. Hollow or solid won't matter. 1.5mm is nowhere thick enough to protect the prop anyway. That is unless you used a stiff metal wire. Why do you want a prop cage on your boat? Just for the "scale" looks?

    Don't stick your fingers in the prop.

    FWIW, a lot of guys don't use prop cages including myself. If you insist on it, You will need to find some sort of wire that can be soldered or twisted together. The first thing that comes to mind would be brass rod in a small diameter... It solders nicely, but it's very heavy.

    the first one i built was with piano wire but it still had a bit of weight to it which is why i thought of using carbon fiber the same as fishing rod
    which can take a fair old bend to it i am just not too sure how much bend i can get in a 1.5mm rod

    It will bend, but I have my doubts you'll get a 12" hoop from it. Only way to find out though...

    Knowing how fiberglass and carbon fiber like to bend, I don't think it'll work... I have a feeling you're gonna need to spend some money and do an experiment. Most if not all prop cages I've seen were made of steel wire/piano wire.
