Jon, With your reply as inspiration I reached out to the global-brain (google) and found a couple of video's. I see most of of how it is done now. Later, in my copious spare time, I will look more into the various techniques I have seen and maybe ask for people to kabitz if I ever decide to take this project up. As a note, I have access to a shop which might have suitable surface blocks (and maybe even straight-edge or two). I would still like to learn more about some of the different touch-off techniques, but it will be a year or 6 before I even think of doing this for realzies...
