Tricky but not impossible.I have all these tools, but I'm honestly not interested in loaning of them out. Helmut, while I'm not too worried about you not returning them, they were just too hard to obtain that I don't want to risk loosing them. I will be more than willing to draw out all deminsions or bring them to Carlisle so you can personally check them out. The adjustable block would be a tricky one, it has a spring loaded plunger that you re tighten with a set screw so you can mic it. I am missing the bolt/stud that holds the assembly together, but think a regular bolt will work.
