Tight Flanges trick

[Joseph Garrett]

I would hesitate to remove the hammer flange rail and set it up in a
"home-made" jig, in order to check the swings. On many actions there is a
wide variance, of placement of the  rail, that is there during
manufacturing. (ie elongated holes to facilitate the action spread) If you
chose to do it that way, I'd make darn sure to take measurements of the
action BEFORE taking it off. IMHO why bother when there's an easier way,
using an upright action cradle?
