Newbie question: Are bridle straps necessary? and more

[Carl Meyer]

I do remember the article about bridles by Jim Ellis.  I was glad to see that.  After years of profanity about bobbling hammers I had recently found that tightening up the bridles some would help.

Everyone says  "More Dip!! More Dip!!.  Well, you could have 3 inches of dip and still have bobbling hammers at very soft playing since the key doesn't reach full dip (if at all) till after the bobbling has taken place.

I believe that among the causes of hammer bobbling are weak hammer springs, poorly shaped or worn butts and excess blow.  The things I try first are tightening the straps, reducing the backcheck distance and widening the let off.  I've even had bobbling hammers after putting on new butts and flanges.  Tightening the bridles was what finally improved the situation.
