it a mixed review. In general it works, but my experience is that the<BR>laser
doesn't always come to rest at the same location. In other words, if<BR>you
give the laser a nudge and cause it to swing back and forth it won't<BR>always
stop at the same spot. Sometimes it's higher, sometimes lower, and<BR>other
times it will come back to the same location.<BR><BR>Also, the balancing wheel
is so sensitive that if you take it off of the<BR>wing and put it back on the
same wing often times it doesn't read the same.<BR>This could be due to the
inconsistent laser or could be that the balance<BR>wheels moves slightly, I'm
not sure. Certainly this makes it difficult to be<BR>sure two wings are
exactly the same when going back to the same wing may not<BR>read the
same.<BR><BR>The only way I'm able to use it is going back and forth multiple
times and<BR>seeing if it's still reading the same. Also, once set, swing the
laser four<BR>or five times and see which spot it lands on most often. This
certainly<BR>isn't very scientific.<BR><BR>What I always end up doing is just
getting things as close as possible and<BR>then flying it to dial in the exact
required incidences.<BR><BR>I've seen threads on RCU where people set zero
incidence on non-adjustable<BR>stabs using this tool, I think that's a BIG
mistake. Flat table with<BR>measuring devices is the best approach.<BR><BR>It
could be that I just have a defective one, but I've heard others that
had<BR>the same experience as I have had.<BR><BR>Keith<BR><BR><BR>-----

<DIV>I Have been using the bar assembly from the GP laser meter and attach a
block of balsa on each side then attach my digital level to the bar with
electrical tie straps. This works great and is accurate to one-tenth of a
degree. Works great. </DIV>
