Does anyone have specifics regarding the use of machine tools (Timesavers, etc) for deburring alclad aluminum flat patterns? Industry standards? Mil standards?
Do any of you know if there was an answer key published for the first edition Peery Aircraft Structures (1950)? Is this book still used in coursework at US universities? Is the answer key available?
I'm not a student and am going through Peery's book for a personal education to supplement...
As a "poor mans wind tunnel" how useful are scale R/C models for designing a full size aircraft? The reynold's numbers are much lower so what can they tell you? You normally can't exactly fly them at super high airspeeds to bring the RN up to an equivalent value.
How about for stability...
Can anyone point me to a reliable source for bearing properties for nickel aluminum bronze (QQ-C-465, Alloy 642, Mil-B-6946, or AMS 4640) as used in NAS (76,77,537,538) bushings?
I have a rule of thumb for these numbers but no firm documentation.
Thanks.

We're in a raging debate regarding the "best" way to clock a steering collar on a shaft (for a gear assy). The collar slides up and down as the shaft rotates.
The argument being which is better- more small contact points (such as a spline) or simpler geometry such as a flat on a cylinder...
