I would try the Charles Stark Draper Laboratory in Cambridge MA (my
fair city) which specializes in such things. Wolfgang

BTW, in my 1987 AJP paper (an accurate determination of the
acceleration of gravity for lecture hall demonstration), I quoted a
value of g for this local (980.386775 cm/s^2) given to me by the
Draper Lab. Note that the number of significant figures implies a
sensitivity of +- 3mm in altitude!

This pdf file has that city, Anthony. Just ignore the instructions...I
don't know what they're for.

Can you describe the demo?

Thanks,

*********
A large cylindrical mass is supported by a string.
Another similar string is tied to the bottom of the mass.
The whole thing is in a "frame".
The "operator" pulls *with two hands" on a rod tied to the lower string.

Wolfgang,

Then Gary's quote for Bergen should be at 38.00 meters? What does it
really mean to have g to so many figures? What kind of apparatus is small
enough to locate it to such a tolerance, or is that the center of mass of
the apparatus????

Hmmm...my post hasn't come through...on the off chance it was an error
on my end here it is again...

This file has the city in question. Just ignore the instructions...I
don't know what they're for.
