Upright Hammer Spring Replacement

[John Ross]

RE: Upright Hammer Spring ReplacementI would do more than push in for a friction fit.
Drill an extra hole and thread the end of the spring in, and draw tight. That way it will have a better chance of staying in place.
Trim the excess, and glue the felt on top.

  That seems about right if you have the springs with the tails.   Just pull out the spring rail, remove backing, pull out old springs, push in new springs (should be able to push in for friction tight), trim tails, replace backing, re-install rail, position springs, deliver and install action, get check.

  It's been a couple years since I've replaced all the hammer butt springs on a vertical. I need to give a guy an estimate. I looked in Joe Garrett's labor guide and it says four hours. Seems to me it took me a lot longer than that - but maybe I'm slow - and besides, my memory ain't what it used to be (I think). Any opinions on labor time once the action is in my shop?

  Thanks.
