Folks,

A quick question regarding the leveling screws for a vertical =
seismosmeter...

If you look at the three leveling screws on the AS-1 seismometer at =
http://www.amateurseismologist.com/, you see that there are two screws =
on the end with the vertical support and one screw on the end near the =
coil.  It is obvious why only three screws are used.  But is their a =
reason for putting the single screw near the coil and not near the =
vertical support.  Also, wouldn't there be greater stability if the =
single screw was actually a fixed pin, leaving the other two to be =
adjustable screws? =20

Just wondering before I drill the base in my next vertical seismometer.

Thanks,
Kay Wyatt
