>How do you measure the counterbearing and with what tool? I fashioned what amounts to a very small sliding bevel,similar to the on found on page 6 of the Garrett Wade catalog--only smaller. I used stiff card for the time being, later I'll do one out of metal. The short,moveable leg needs to be short-1" or so,wedge shaped coming to a sharp point.(I wish we could draw pictures on this thing). The long leg is not much longer- 2-2/12". The two legs are held together with a tiny machine screw and nut. Lay the longer leg on the string(s) and position the shorter leg to line up with the upper duplex string. ( you need to hold you mouth just so:) ) Tighten up the nut. Transfer the resultant angle to a piece of paper, extend the lines described by the two arms and measure the angle with a protractor. Similarly, you can measure the angle from the speaking length up from the bar from underneath with the action removed.
