No, I just ignore the source. A great machinist he may be, an A&P he isn't.
Since it is Christmas... I will let this slide... And...
I do NOT want to be considered an A&P..... Earlier in this thread you claimed you just "follow the book" on doing stuff..... Heck,,, we can teach monkeys to do stuff like that.....
It takes ALOT of skill to build a plane from scratch, design and engineer all the components to stuff in a 400 HP motor in a airframe the kit maker wanted 150-180 HP in it..... Including designing the engine mount and ALL the accessories needed to make it safely fly... I am 11 years, 500+ hours and 100,000 miles on my homebuilt and it works PERFECTLY....
Now. when I get old and feeble, I might become a A&P, so I can take a certified plane, disassemble it, sand /bead blast the real corroded parts, scotch brite the other corroded parts. Buy a few cans of Krylon and make it look real perty..
Follow that by totaling a restored plane by poor airmanship causing a ground loop.. or worse yet, build a motor for a unsuspecting couple and have it critically injure them both, and then get on a website claiming it was NOTHING you did...
I will put my successful results against yours any day old buddy....
Merry Christmas Tom...
