    C42 Wind screen

    Hi, I need to remove the wind screen hoop tube on a c42, my main concern is how best to remove the pop rivets without damaging the screen . I believe the rivets are soft aluminium and would need drilling out. Is this the only method or are there other ways of removing them. I assume the screen is Lexan and not Plexiglass which is more prone to cracking under stress.

    I have carefully drilled, but just deep enough to weaken the 'flanged' part of the rivet head so you can break it off sideways with a regular screwdriver blade or similar. So the drill is bigger in diameter than the rivet core body.
    Alternatively where that was impossible I used a Dremel mini grinder to remove the rivet head, then push the rest back through the hole with a thin dia rod/. A light blow might with care assist in this. Problem with Dremel is it gernerates a great deal of loacalised heat which the Ali conducts into your Lexan. This is NOT good !
    So a slow process.

    Perhaps doing several rivets a little each and returning when cool is one way ?

    Thanks for the advice guys, slow and gentle seems the best approach.

    The cost of a C42 screen makes it very worthwhile to buy a hand drill. They are much more controllable than any electric drill and, because you can drill slowly, you won't generate too much heat.
