I am looking at making a couple of lensboards for a Wisner and have a question on the lens plate drilling hole tolerances.
What is the tolerance on this? For example, a Copal 0 is specified as having an opening of 34.8mm. Not surprisingly, this is not readily available. I can get a 34.925mm (1 3/8") or a 35mm bit. A small amount of run-out in the drill press is also likely to cause it to be every so slightly larger.
Are these within acceptable tolerances? Will I see problems with a slightly oversize hole?
