[CAUT] Hamburg leg bolt

[Bob Hull]

Caut List,

The Hamburg D here almost hit the floor as some
students were moving it last week.  The bass leg came
loose but they caught it in time and put a piano bench
and books under it.

I found the bolt that goes in to lock the plate 
turned as if stripped because the inner threads or
sleeve is broken into two pieces. The sleeve material
is soft and thin. Half of it is still in the hole and
the other half came out with the bolt.

I'm checking with a Machine Tool and Supply store to
find a new sleeve and may have to change the bolt as
well.  Do you think the sleeve is in there just as a
force fit? I'm thinking about using epoxy.  I didn't
try to look in the Steinway catalog for this item, not
wanting to  wait to get something from NY or Germany. 


The piano faculty is wondering if the piano would be
safer on a piano truck (spider?) instead of the double
casters.  It is moved quite a bit.  

Does the truck do a poor job of keeping the piano
level since the ends of the truck arms flex downward
under the weight of the piano through the legs?  And
what about the connection of the piano to the floor
for better sound?  If the floor is hardwood on top of
concrete is there any value to being connected
directly versus being on a truck?

I'd appreciate your ideas on the repair and the truck
versus casters question.
