Hi all, I, by accident, ordered some sets of front rail cloth punchings but received 3/4" diameter.  I might want to send them back, but I was wondering if there is a huge difference in the feel over the 1" dia.  punchings?  I assume the 3/4" dia.  are for uprights, but aren't upright keys' widths pretty close to the same as grands?  I know there are slight variances from make to make be their original design of the width from the width of the whole keyframe.  3/4 would probably be required for 7/8th size keyboards, but why do they really make two sizes? Thanks for your ever-ending wisdom :>) Paul
