Question for the experts...
The rear spar for the vertical stab on the 7A has an eighth inch thick doubler that, according to the drawings, permits optional lightening holes. Two of the holes are 2" dia, and 5 are 1.5" dia.
It appears as though I have two options if I want to cut these lightening holes. I can buy the Rotabroach cutters from the good folks at Avery for $ 175; or, I can get an adjustable circle (fly) cutter from STS for $13.95.
My question is... do the Rotabroach cutters perform in a sufficiently superior manner to justify the >10X cost?
Any and all comments and suggestions welcome.
Thanks in advance! - - Tom from Sacramento
