Paul, 



Were you to (re)drill the flange screw holes, a drill press and vise would maintain that angle for you.




Alan Eder



 Is there a way to plug the holes and
re-drill?  I have a cool DeWalt drill with a built-in bubble level,
so I can get the exact angle every time. It would even be better to create
a jiggy thingy to guide the drill from hole to hole to be absolutely consistent.
Anyone done this sort of thing? (I'm sure the  New Yankee Workshop
guy has something like what I'm talking about.) I can't say my hand and
eye are good enough to really put the bubble at the exact correct point
88 times. The level is just a "guide"  But..How to establish
the action perfectly at level might pose new problems.  My main work
bench is an old bowling alley lane segment about 6' long.  It is supposed
to be absolutely level, but it has warped over time. It's continually warped
evenly though, so a jiggy might still work.

Ed and all,



I tested a bunch more...Same result.
 It's not the depth of the screw..  I think they were drilled,
poorly, by hand at the factory and go in at different angles.  The
holes on the brass rail are all straight (in the brass itself, that is).
The flanges don't sit exactly flush with each other=2
0and think the angle
of the holes are the problem.  Is there a way to plug the holes and
re-drill?  I have a cool DeWalt drill with a built-in bubble level,

I told you all this was a puzzler!!
:>) I'm sure puzzled!!  We have several "M"'s from  1966
here (when the building was new, so they bought a bunch en-mass).  I'm
going to check them all out and see if they're all the same.  We have
some from the 20's and 30's, and also late 70's/early 80's  so it
would be interesting to see if they are more accurate, unless they aren't
(as Kent Webb likes to say! :>)



Keep 'em coming! Your thoughts are getting
closer to the "fixer".

Re: [CAUT] Friday Puzzler














Paul, you're gonna have to work this out.

 

1) Are some screws too long?

 

2) Are the holes drilled to different depths?
Can you drill them further yourself?

 

3) Is it really different depths, or different
length screws, or are the holes drilled or messed up out of alignment so
that the screws go in at different angles, thereby causing the flanges
to set on the rail at different angles from one vertical plane (not rotating
around the axis of the screw, but rotating around the axis of the rail).


 

4) Is this original, or did someone repair
loose holes or use oversize screws to create the irregularity?

 

5) Are the flanges irregular?

 

All of these are possible, and probably something
else as well.

 

You have to look, see, and tell us! Test
more than 3 samples.

 

Ed S.

I think it is indeed the screw holes
in the rail.  For fun, I just screwed in the screws with no wippen
on these 3 samples I took off.  Well, what do you know...the screws
are at different heights!   



Is there a way to remedy this, or am I stuck.  Is this a replaceable
part?

Hi gang! 



I'm puzzled!  I'm now working on a 1966 Steinway M with a strange
thing going on.  I looked and the wippens and they're all askew and
not in any kind of even line on the brass rail. Some places, they're nearly
2mm off.  I tried to attach a picture, but it was too big. I'm still
getting used to my new camera and iMac (having been a life-time PC guy).
  



I checked the wips themselves, and they're all good.  I can't "see"
anything off on the brass rail, but only took off 3 wips in a row to check
the rail out. 



Have any of you ever come across this?  I've got a message out to
our tech support guy about the picture, but perhaps you know what I'm describing.




Thanks for any help. 



Paul
