Checks cause hammer bounce ?

[William R. Monroe]

Not to beat a dead horse here, Ric, but it seems like your diagnostics are 
leading you to the balance rail.  I recognize that there are still 
possibilities elsewhere, but perhaps it's time to get that dial indicator 
after all.  ;-]

maybe:

or something of that nature.  I'd have to look up Ron O's article, but I 
assume this indicator would work well enough.

Best,
