Epoxy work surface

    Hi all,

    I've found some carbon fibre cloth floating around from one of my previous builds and figured I should use it in something. Last time I worked with cf and epoxy though, it was done in a similar fashion to a surfboard - placed on a stand and done one side at a time. This time though, I need a work surface to do the glassing on. Wax paper seems to have completely disappeared around my neck of the woods, so do any of you with epoxy experience have any other recommendations?

  2. Cool that's my next project...but I lost my rool of CF in the shop! Check Amazon they have it and you might be able to find it in something wider that a restaurant uses. Have you ever used a vacuum bag system? I think I might try it next time.

    Sorry if I have more questions than answers. I'm about to another one and this popped up at the right time.

    I've not used vacuum bagging before, I've only done hand lay-up work. I can't try it for this one either because I want to use the cf as a backing to a sort of chambered frame.
    Last time I used surfboard maker's epoxy, but this time I'm giving a type of marine epoxy a go. It's water-based and has a little more flex, so it's (apparently) suited to going over timber a bit more.

    TB member @MPU has done some brilliant work with CF layups over the years.
    First thing I would do is reach out to him. I have only seen him use molds/vacuum, but I bet he has plenty of knowledge.

    Here is one of his threads:

    Clear packaging tape is an alternate to waxed paper, for making a non-stick gluing surface. I have several gluing beams that I use for clamping up necks and bodies. I cover the top surfaces of them with clear packing tape. Woodworking glues and West System epoxy won't stick to it.

    Another alternative is to use a sheet of aluminum, wiped down with wax.

    Epoxy does not stick to polycarbonate. (Lexan)

    Epoxy doesn't stick to the large black yard or contractor bags, either, so taped down, they make a good bench cover.
