In this thread, http://www.metalworkingfun.com/thread-791-page-4.html
I read Stevec 's post regarding tool placement in a shaper clapper, described from a 90 degree position. Can this also be called the tool holder leading or following the clapper?
From your comment, it sounds like setting tool holder behind the clapper head is generally the best practice to prevent the tool digging into the work. Do I have this correct?
Any other general "rule of thumb" to share, I would deeply appreciate.

I recommend you search for "Machinery Repairman 2 & 3" the training manual for the US Navy's MR's or machinists as they are normally called. It has a section on shapers and how to grind their tools. I learned how to run a shaper when I went to the MR A School and later learned how to run a planner while onboard the USS Samuel Gompers AD-37, a repair ship. BTW, they are the only machines I know of that can produce a flat knurl. Also great for making blind internal dovetails.
