Need help repairing whippen jack!
« on: April 15, 2020, 07:16:22 PM »
I have an old upright piano and periodically some of the keys stop playing. Under normal circumstances my piano tuner comes by to fix them. But times being what they are, I am trying to avoid any unnecessary visitors so am trying to see if I can fix it myself. I have diagnosed the problem as the key having a loose jack on the whippen (I think those are the correct terms). I saw a couple of sites giving general directions for gluing it back into place, but they lack sufficient detail for me. The biggest issue that I can see is how do I reach the jack? Do I need to remove the whippen and if so how would I do that? Any help would be greatly appreciated. Being stuck here in the house, I need my piano to be functioning again.

Thanks so much in advance.

hi,somberg
1. Need remove an action from the piano. Loosen there 2 or 3 screws on which it is mounted and remove it's.
2. Find your whippen which we need glue off .
3. Disconnect (Bridle tape)  connecting the hammer with a whippen.
 4. Unscrew  a whippen from wood plank (back side). Now it's should fall down.
5.Paste an jack with one drop PVA into a whippen . Press it down with effort and few part  glue get flooding to sides of a whippen. After 3 minutes remove it's glue from two sides of a whippen. And, most importantly, an jack should stand without a slope. Namely, at 90 degrees.
 6. The most important operation is to put in gluened whippen in native place. On the opposite side of the hammer setting  a whippen in such a way that an jack that you pasted comes in and gets under the hammer . Then align the screw hole of a whippen with the hole in an action and screw it's. Now check: when you press a whippen with use your finger, the hammer should work.
 7. Using medcine tweezers, pull (Bridle tape)  through the window of the crochet hook and insert it in (Bridle wire)  .
 8. Make sure EVERYTHING works.
9. Insert an action into the piano accurate. It is very important that pins of iron's plate (2-3)  on  into the holes of an action at the same time. To do this, see: at the bottom of an action there are legs (2-3) pins that must be installed in metal halfcap holes. Usually there are 3, 2 along the edges, one in the middle. Only after whole connecting it's need  slight move an action to plate and  press .

1. Remove the action from the piano. Detach any pedal rods from the action. Locate the screws or nuts holding the action brackets to the piano’s plate. Remove these fasteners, tip the top of the action toward you, and lift the action out of the piano up by grasping the hammer rest rail and lifting.

2. Locate the whippen that has the loose jack flange.

3. Disconnect that note’s bridle strap from the bridle wire on the whippen.

4. From the back of the action, remove the whippen flange screw and remove the whippen.

5. Remove any loose glue of or other debris from the jack flange and whippen check for a dry fit. Apply one drop of PVA glue to the whippen where the jack flange will be attached. Be sure the jack flange is properly aligned, 90 degrees to the whippen, and there is sufficient glue as indicated by some squeezing out. Let glue set a few minutes and remove any excess.

6. Reinstalling the whippen can be a challenge. Be sure the jack spring is seated in the whippen and jack. Pivot the jack against the spring enough to position it against the hammer butt leather as the whippen flange is also being positioned against the whippen rail. It is often necessary to have the whippen flange screw already in the flange due to interference with the damper spoon. Attach the whippen flange to the rail with the screw.

7. Keep the whippen raised in the normal position until the bridle strap is reattached to the bridle wire or the jack may jamb on the hammer. On many pianos the bridle strap threads through a hole on the hammer butt back stop.

8. Check for proper operation of the repaired note.

9. Replace the action in the piano. There are a number of studs in the piano that the action brackets rest on – one stud for each bracket. Handling the action by the hammer rest rail and tipping the top of the action toward you, position the action brackets onto the studs. Often it is easiest to judge when the action is properly aligned by observing how the whippens will rest on the capstans. When the action brackets are resting on the studs, tip the top of the action  you toward the piano’s plate. Attach the action to the plate with the screws or bolts. Reinstall or re-position any pedal rods.
