lens board / Copal 0

greenspun.com : LUSENET : Large format photography : One Thread

Can someone give me the measurements for Copal 0, and Copal 1 drilled hole size in the lens board? Thanks.

For lensboard holds, Schneider gives 34.8 mm for Copal #0, 41.8 mm for Copal #1. The holes don't have to be made to 0.1 mm accuracy. In fact, the numbers that S.K. Grimes gives are slightly less.

These and other dimensions are given by Schneider at http://www.schneideroptics.com/large/shutter/shutter.htm If you are making your own boards, note the ranges given for the thicknesses of the boards. Dimensions are also given by S.K.Grimes at http://www.skgrimes.com/products/index.htm
