There is a small setscrew in my new large format lens that requires boring a hol e in the lensboard in order to countersink the screw (presumably for stability). This appears to be an optional process. My Toyo lensboards are very thin, and I am reasonably sure that I will mess up this process if I try it. Is it reall y necessary to go to the trouble of accomodating this setscrew in the board for lens stability, or is it truly optional? Thanks for your responses.
