Hints For Homebui lders Easier Communication
Do you have a problem with wind aff ecting your voice-actuated intercom?
On the Light Sport Aircraft Yahoo group, Ron Hill had a solution for his uncooperative voice-actuated intercom. His mic in the front cockpit, where he sits behind the windshield in his tandem two-place Challenger II, works fi ne, but his wife's intercom was always being actuated by wind noise locking out Ron's mic. This made conversation between Ron and his wife nearly impossible.
He tried the Oregon Aero MicMuff Mic Cover designed for high noise environments. It has a foam microphone cap and a little vinyl bag cover. But that still wasn't enough to solve the problem. The dynamic wind pressures were very different. His solution was a mini windshield for the mic. He took the bowl of a plastic spoon, trimmed it to size, then inserted it between the cover and the foam over the mic, acoustically covering the front of the mic. This refl ected the wind pressure enough that the wind noise was balanced, giving them both had about the same actuation threshold. Ron says this fi x has restored marital bliss in his Challenger.
Cutting Plywood Gussets
Wood wings typically have a large amount of thin, small plywood gussets, many the same shape. Timm Bogenhagen from the EAA staff shows you a simple yet speedy way to stack and cut many gusset pieces with one cut. Watch the video.
Safety Wiring
Brian Carpenter, of Rainbow Aviation in Corning, California, demonstrates how to safety multiple fasteners together, watch "Safety Wiring Multiple Fasteners."
In a second related hint, Brian demonstrates safety wiring via the "Single Wire Method." Brian is an A&P;/IA, DAR for LSA and experimental amateur-builts, sport pilot instructor examiner, and CFI. Brian also serves as an EAA technical counselor and fl ight advisor for Chapter 1148.
