[SEL] Monitor

[Curt]

Jim,
Congratulations on the completion of your Baker Monitor! Maybe I need to 
send you Devin's so it will actually get done!
Running Devin's I noticed exactly what  you have observed concering the 
sensitivity of the needle valve.  His needed a new needle valve anyway, 
so when I made it I halved the taper. In otherwords it was much less 
stubby. This should allow a finer adjustment.
Here is the link of the drawing I made of the needle valve. I made this 
drawing a year or more ago and can't recall if this documents the 
original needle valve or the way I actually made it. You can compare it 
to the one you have and see. Maybe you can experiment with an even 
narrower taper to allow an even finer adjustment.
