Perusing the on-line plans for the Boll Aero18, I’m puzzled by the use of a multiplier against some hole dimensions. An example for the press fitted crankpin is shown highlighted below. It’s not the number of separate holes, here there’s only one. Is it perhaps a CAD thing, can someone enlighten me please?
