[CAUT] sanding let-off punchings

[Fred Sturm]

	It's nice when the letoff rail can be removed. Makes for easier  
access. (I do remove them on uprights, when I go to that trouble).
	I made little wooden sanding paddles the width (plus a little) of the  
buttons, for individual ones that are out of line with the others.  
Popsicle sticks are about right. Nail files (with rough garnet grit or  
the like) are a little flimsy but can work. Where possible (meaning  
the bulk of the buttons are pretty much level with one another), I  
gang file, using those metal flexible paddles from Pianotek  
(PermaGrit, I think is the brand). So I go over a section with the  
metal paddle, then touch up the ones I didn't quite reach with the  
little wooden paddle.
	Same kind of thing ironing them: use the full clothes iron over the  
whole section, then touch up using just the tip on the ones that are  
out of line. Or use a keybushing broach in a heat controlled soldering  
iron. DO pay attention to the angle. It's easy to iron them all "off- 
parallel" (How would I know? <G>) Not a good thing. Kind of defeats  
the whole purpose, and turns it into a cam effect.
