Building Lasers Not??

[ronlock]

Lets remind potential new pattern pilots reading this list,  that there are a lot of good flying
birds out there that were set up by eyeball and rulers.   With a bit of trmming, they fly
fine and can be competitive.

  .1 degree is also just a shade over 1/32" difference EACH at the leading and trailing edges.  Understand that we need those kind of accuracies for best, but I believe most folks do NOT resolve incidence to 1/32"....but I understand the need to state precisely.

    Bob,

    A tolerance of .1degrees is not very close to set the incidence.
    Over a wing root of 20" it works out to be .035 inch. This is the max.
    positive incidence I use on the wing when setting up a pattern plane 
    with the stab being set to zero.  A  .1 degree tolerance could give me 
    a setting between 0 and .070 positive when setting up a wing with 
    a 20" root.

      The purpose of the ones I have is not to check incidence, but to verify alignment "square", and "parallel"...currently, a lot of folks use different methods, some height gauges, some fixtures.  When building a plane, I have always struggled with getting the stab square to the fin, and then the wing parallel to the stab...and these differences sure do make a difference in how a bird trims out.

      Incidence is checked with our electronic digital levels, at .1 degree accuracy :-)

        This discussion is getting a little too technical. 
        Seriously though, being new to a lot of this, I would be 
        interested in more details about how to use these laser 
        thingys to check incidence. I am completely new to 
        incidence checking so this probably sounds like a stupid 
        request.
