Matthew Yes, the height of the sharps is very important. Once you've raised them to the appropriate height, you will need to check to see if the dip is also correct. There are two ways you can do this. One is to see how far they travel down. If the top of the sharp is half an inch above the white key,and the sharp needs to travel 3/8", you will be left with 1/8" of the sharp above he white key. The other way to is press the adjacent white keys down, along with the black key, and feel across the back of the keys,just in front of the capstans. All three keys will need to be level with each other. Unfortunately, this will require a considerable more amount of time, which you probably didn't estimate for. All I can says is, that's part of the learning experience. Sorry.

Have run into several issues to which I would covet your assistance. 1.) Exactly how much rise is adequate? 2.) I am having a heck of a time regulating the sharps. The naturals are coming along fine (i.e. let-off, drop, rise). The sharps are only 3/8'' high as opposed to the specs of 1/2''. Could that be the problem? And if so, and increasing the height to 1/2'', how would that affect the dip? Before messing with all the sharp heights, I thought I would get suggestions first. Thank you!
