    I'm following this thread with interest Sile, I only have a small sink but its at the end of a long formica counter top and maybe I might make this into a sink if your plan works well. Please let me know.

    MDF is not ideal. But it should work with two coats of West system epoxy. Before you coat it, mix some epoxy with fine saw dust, or even better, with silica (available from west system). Make it thick like mayonnaise. Then use it to make a filet in all places where two MDF-sheets meet. Within 24 hours coat everything with clear epoxy. Then coat everything again within 24 hours. If you wait more than that, you will need to wash everything down with water and then sand it before applying another coat. Be sure to coat the inside of holes for drains etc at least two times as well. Also, coat the outside at least once. Round all edges a bit too, since epoxy won't coat sharp edges.

    My sink was from a mold made by a friend. he built a negative plywood mold and we took it to a boat company and had gellcoat release coating sprayed on it and then the fiberglass. It's basically a boat hull in the shape of a sink. Works great! I guess I've had it for thirty years.

    Great advice Matti thank you, I've seen sports hall flooring manufactured out of MDF dust mixed with glue and the finish is hard as a rock, so it's an excellent idea to use the epoxy mixed with sawdust for the filler.

    I'll let you know how it goes Fintan, I found a place in Dublin http://www.wallerwickham.ie that does West System Epoxy but unfortunately as most businesses are closed for the Bank Holiday weekend, I haven't been able to get an answer.. I'll try again Tuesday.

    Thanks again for the advice everyone.

    Thanks for the info Sile. I think my father-in-law uses that company, he has restored a big boat.

    I wonder if I would be too ambitious to try to make a sink for my wet bench which is 128" long and 30" wide. It's really L shaped with another bit 33" long again by 30". Maybe the L bit would be too much trouble. The bench top itself is a fairly solid formica kitchen counter.

    This really has me thinking

    Im thinking of going about 8ft long and 36" wide. Even considering an L shape as well, but it might take up too much space and I dont think I need to go that big.

    The latest on the West systems epoxy is that you need a coat of epoxy followed by a 2 pack paint system followed by an interim coat of paint.. all coming in somewhere in the region of €40 + VAT per coat but they don't recommend MDF as a base..
    So I'm back to where I started unfortunately.
    Has anyone ever tried Perspex to construct their sink? If so I'd be very grateful of any advice.
