This afternoon I fitted the nut and made a bone saddle for my new bridge. Bone smells horrible when its worked (especially with power tools), and I also have the BSE question in the back of my mind as I generate clouds of bone dust. I have the vacuum cleaner running the whole time, but still I worry... The nut will be fine I think, but the bridge looks as if it will make the action too high. I may have to remove rather a lot of material from the feet and so will get close to the little winged holes.
