A very quick method involves pressing down on the top of the glides using the underside of the pin block as leverage. Put the action in with the cheek blocks screwed down. Back off the glides using a tuning hammer or special regulating tool. You will be able to tell if the glide is backed off by pressing down on the top of the glide with the regulating tool using the underside of the pin block as a leverage point. If there is space under the glide you will see the keys flex slightly downward. Back them all off and then go through one by one and turn the glide bolt down until the keyboard stops moving down when you push down on the glide. Repeat the procedure a second time to double check. If you have a hard time seeing the keys move downward, hold a ruler against the front of the keys for a reference, or you can also use a Jaras white key leveler--you see, it does have a use.
