Tom,
Thanks for the reply. I am restoring a 1923 dental cabinet. The drawer is ¾″ stock with a ½″ hole. I am assuming the lock is a cam lock that rotates 90 degrees down into what looks like biscuit joiner cut-out. The cut out is ⅛″ which would be a total of ⅞″. The back part of the drawer has been cut also which could have been for a small mortise type also. I will try to get some pictures to help. Thanks!!! Allen :roll:
