I've acquired a Hipshot bridge from the chap who I got the kit from, so that will go on. He got some longer posts for it, but I think I may investigate putting some threaded sockets in so there's something a bit more mechanical. I've filled the holes with epoxy and microfibres and will redrill them so hopefully that will stabilise the wood a bit. I'm also scraping a flat in the body between the three bridge holes so the bridge will be sitting down firmly on the wood. To my surprise I haven't gone through the veneer yet and I'm well on the way to getting an acceptable surface. I guess the advantage of the 3 point bridge is that it doesn't contact the body so can go on a curved surface.
