Erwin Bearing Gauges

[Erwinspiano at aol.com]

Hi Jurgen
   Thanks & you are welcome. You can use  them in the bass.  Just make one 
with a long arm & in the end of the  arm facing down install a flat head screw. 
Retract the screw so it's flush  with the bottom face of the gauge. Place the 
gauge on the speaking length of the  bass string so the screw is just over the 
plain wire in front of the bridge  pin.  In this position there is a big gap 
between the plain wire & the  screw.  Turn the screw down till it touches the 
wire. Now you're ready to  check bearing however the gauge on the speaking  
length must stay  positioned on the copper & can not be held flush against the 
pin which  will scew the results slightly but still you're in the ball park. I 
dont' touch  down on the any portion of the loop but only on the single strand 
of wire.   Close is good enough here in my Opinion.

Dale,  thanks for the recent photos of your bearing gauges.  What do you 
do  for the bass sections?  Can these be used in the bass?  Do you  
measure the OD of the bass strings and do the math to come up with the  
deflection?  Or is it impossible to snug the gauge up to the bridge  
pins in the low bass due  to the thickness of the  strings?
