Inconsistent lost motion is often caused by a bent hammer rest rail/soft bar in an upright. But this dosen't explain why you have never seen it in an upright. I have had trouble like this in consoles where the action brackets were loose or poorly adjusted, but that dosen't explain why you need to take it in to the shop. Nor is a loose key bed which I have seen this problem in; you cant just tote it to the shop. I give up.

That's the clue that tells you it ain't the mounting posts, or anything having to do with anything not self contained within the action. I'd not only never seen this in a vertical, I'd never even HEARD of it before. The wippins, jacks, and flanges are intact. The hammers, butts, and flanges are intact. The dampers, levers and flanges are intact, and everything's screwed down securely to the rail, including the damper lifter bar hinges. The rail is firmly screwed to the brackets too. Spooky, isn't it? Ron N <
