New to me 112, I need some advice
« on: February 03, 2020, 10:00:18 AM »
All -

So happy to have found this resource!!!   I was at an estate sale yesterday, and picked up a mottled pink Wurlitzer 112(a).   Serial number is in the mid-4000s.   Build date is 1/16/1956.   It has legs (but they're the stool legs I realized when I was about a foot and a half off the floor!!!) and the pedal.   Amp works - was popping, I re-seated the tubes, and now I've just got some volume-linked hiss (I assume I'll be replacing the filter caps in the metal can)...  All the tines are there.   Keys are perfect.   Looks like it was hardly used.   It had been stored in an unheated garage for eons, but condition wise, I'd give it an 8+.

Here's my question.   About 7 keys around middle C (from Bb to E) were not in position when I got it (turns out they were inside the case of the keyboard).  I installed them by lifting the hammers, etc. without difficulty.  The problem is (and I'm sure there are people already rolling their eyes) - the mechanism above these keys isn't sitting right.   I'm not a piano technician at all, but am pretty handy.   I downloaded the 112 manual, and studied it, and it appears to me that the "fly" (part number 9 in figure 6) is leaning back on these notes, allowing the butt to droop (whose butt wouldn't after 65 years... :-) ) down toward the key when looking at it from the front.   I believe I need to somehow recapture the fly between the regulator screw (part number 15) and the butt (part number 11).   Unfortunately, I do NOT know how to do this.  :-)

I tried for two hours using stiff wire, soft wire, long pliers, key strokes, front side, back side, you name it.   I failed.  Does anyone have a hint on how to accomplish this?   I was thinking maybe I would put the keyboard facing down across some stands and let gravity do the work as I manipulated the keys.   Any thoughts or advice would be greatly appreciated.  GREATLY APPRECIATED!

I'll keep everyone up to date as I progress - I suspect others might benefit.  I'll add pictures as soon as I can figure out how to shrink their size.

I'm located in the Boston, MA area if anyone wants to check it out!!!

PS - Just FYI - I had an EP-200 in the late 70s which I dropped off at our local Goodwill in about 1994.  A little bit of regret there.   :-)   And I have had a Stage 73 for a long time - need to pull that up and get it back in gear too!)

I would love to help you with this, but I have only played 112's, I've never owned or serviced one. I will look at my service manual to see if I can help with the action problem(s) It sounds like the jacks (formerly called flys) are tripped, which should make it an easy fix.

Dropped off a 200 @ goodwill?  Wow.

I'm looking at fig 6. In the 112 service manual. #9 is the jack here, but part #5 is the reed bar in this diagram. Are the butt springs, (on top of the hammers) in tact on the keys that you are having problems with? They could possibly be broken off. If you lift the hammer up, you should be able to pull the jack forward with a small hook of some sort, resetting the jack. Use a bright light pointing into the action. You may want to remove the corresponding keys to do this, but maybe you shouldn't have to.

I'm assuming this is a regular 112, and not a 112A, correct? The actions are completely different on these 2 models. The 112A is the same as the 120 and the 700 actions.

Steve!   I think you and I are 100% on the same page as to process.   Thanks so much for the reply.    Your suggestion is exactly what I'm planning to do (hopefully tonight).   Yes, I've already used the bright light (definitely necessary).   I need to figure out what kind of really thin, stiff wire I can find to make a hook out of...   :-)
I checked the springs, they all appear good.   I think I have to do this with the keys IN, as because if I try to do this with the keys out, I can't lift the back end of the action high enough to wiggle the key in.   And I'm not comfortable lowering the adjustment screw in the back on six or seven keys (yet) to get them in, and then raise it.   If I fail, maybe that will be my next idea.
As to action and the manual, the 112 manual definitely shows my action.   
THANKS AGAIN!   More to come!

Yeah - I only buy at Goodwill now...   :-)

A piece of house wiring made with a hook on one end should work...

Total success.  I used a rather large tie wrap, and on the end that has the "capture" on it, I used a sharp knife to make a very small /~1/16" hook.  Worked fabulously - all keys are working and even height-wise.   I have other questions - I'll start a separate post for those.  THANKS AGAIN!!!

It sounds like you have a regular 112, but your first post says 112(a)...

Sorry about that confusion - the keyboard is definitely a 112.   SORRY!

That's ok, I figured it out from your description of the action issue. No worries.
