    This and that.
    I have a fibreglass panel 60cm x 120cm (3mm thick), and I need to cut it lengthways. The cut is curved.

    So far, it seems the best method is a Dremel, but I could do with some advice.

    Is it best to cut wide of the line and then sand back to the mark? If so, what should I use for sanding?

    Am I better off with a (manual) coping saw?

    Plus any other words of wisdom you may have.

    Thanks

    Use a facemask is the first thing that comes to mind.

    Take it as a given that I'll be getting Mrs D to seal me securely into a dustbin bag before I start. ;)

    any saw will pull the laminate away from the matting unless it's incredibly sharp and very fine in which case if you are using a hand saw it will take you hours

    A dremel with a rotary cutting disk will do a decent job but following the curve may well prove tricky.

    If it were me, I'd use a jigsaw on a slow speed with a fine cutting blade and tape over the area you intend to cut. Work steadily, don't let the blade get hot and be prepared for a little filling afterwards

    Fortunately, I reckon the curve can afford to be less than perfect, so the Dremel is the way I'll go.
