Lowell Component Downbearing Gauge

  Sorry to chime in late.  Life &  all.
   I thought it might be interesting to note that on  my most recent project 
Stwy A-2 that in checking the net residual bearing with  both the Lowell gauge 
& the Wooden bearing gauges that the reading came out  the same at 3/4 of a 
degree & a bit more in the trebles. SO the board is  half squashed as intended.

Well, the purpose of my message was merely to point out the  
deficiency of a tool that resolves only to one tenth of a degree and  
to show that Dale Erwin's primitive method can achieve more than  
double the accuracy of the Wixey digital gauge.  Steel strings at  
pitch are not going to deflect to distort the measurement either 
under  the weight of the Wixey gauge or under the light pressure of 
Dale's  fingers and I can think of several far less reliable  methods.
