John, I have one of those rubber blocks (a memento from BAe in the 80's) They were used by the Spinner to polish up work pieces. I used mine to clean my N gauge track. I've also inherited one of those stones with a slight taper. Any idea what they are for? why the taper from edge to edge?
Three or four years ago I set about designing a guitar tremelo unit that would not require routing the guitar body. To secure it I would have needed some Allen head wood screws. The only place I could find at the time was this place. They seem to be available from several suppliers nowadays.
Ed.
