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: http://www.leevalley.com/wood/page.aspx?c=2&p=32525&cat=1,43513,51657 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, William R.
