A friend of mine had an old book press in his shop that he bought from an estate sale years ago. When he found out I was looking for a shop press, it landed in my office. I finally had a chance to try it out last weekend. I used an 8" (diameter) Molon Labe sign made from 1/8" steel plate I had in the garage for the pressing. As a first test, I cut out an insert that fits into the dash of my 2006 F250. I was a little skeptical that I could get enough pressure with the book press to make a permanent mark, but it actually pressed relatively well. I left it in the press for just over an hour before letting it dry and dying the embossed region black. I've already ordered a pair of 1/4" plates cut to fit in the press for a better surface as well as some additional embossing plates (buddy owns a steel shop).
