Also, in regard to ink--I have some of the Graphic Chemical & Ink Co ink sold by B&S. They repackage it into smaller tins than you get direct from the factory. This ink works well, but doesn't keep--it hardens all too quickly. That is why I like the VanSon ink. It stays useable much longer than other inks.
David Lewis' ink is excellent, but rather expensive for the small quantities he sells. I bought VanSon from a local litho supply. The black was about $12 for a tin, and the red, blue, yellow, and orange varied from $17 to $20. But these inks will probably last me for the rest of my life. Their consistency is smoother than any other ink I have used.
