Urgent ! Incidence Meter Question

[Bob Pastorello]

Or - locate and buy an electronic digital level, buy a longer aluminum cross-bar, make a bracket to mount the new level to the new bar, and THROW AWAY the Robart, keeping only the parts that permit you to clamp onto wings/stabs.

I did this years ago to save what remaining hair I had when trying to use a Robart on a biplane.  It cost a few bucks, but allows for on the fly "rezero-ing" to check relative measurements to each other, and allows zero reference to gravity/bench for setting overall baseline.

Mine isn't for sale. :-)

  Scott,
  As has been stated, use the meter from the same side for all 4 test points (L/R wing, L/R stab).  Put the gimbal inside the front clip and the clip inside the scale.  Only adjust the rear clip when moving it between the surfaces.  
     There is no need to "zero" the scale.  Use it as a relative scale.

      I am currently installing my wing adusters on my Focus 2 and I am trying to calibrate my Great Planes Incidence Meter. I placed the meter on a perfectly level table and set it for Zero Degrees. I decided to rotate the device 180 to see if it would still be level (the laser was roughly facing north and now is facing south). The degrees changed positive 1/2 degree. I thought I might have moved the placement of the laser so I secured everything possible with tape and rotated it again. Same thing. Does anyone know what might be the problem???

      Thanks in advance!
