Paul has a lot of great ideas that help add details to a project and they cost next to nothing. Here is a video he did on variations on a shop-made scribe he showed in another video. I have one in the shop somewhere that I made using this idea for creating beads on the edge of a board. I also made it for double use by using a large screw and a small screw so I could make two different size beads.
Mike a copy of that belongs in Paduke's Shop Hack's thread so I put a copy of it there.
Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.
