I've been searching unsuccessfully for an article I've seen, here or elsewhere, describing a modification that can be made to the clamping pads for the front standard of Pacemaker Graphics that allow front swing. As I recall, this involved rounding off the corners of the clamping pads, accessible by removing the front standard from the rail. It appears that this could be done with a small grinder wheel.

There have been earlier posts here looking for this information unsuccessfully.
