Thought the list would benefit from this... and maybe keep all of us a little saferin the skies.Motion Induced Blindness - videoATC, radar controllers and pilots know this but who would have thought about drivers.Unfortunately we know that's not a problem for the people texting whiledriving. Indirect observation is pretty critical for preserving night vision while drivingat night also. This is frightening! It works exactly like it says, and is one major reason peoplein cars can look right at you (when you're on a motorcycle or bicycle)---AND NOT SEE YOU.>From a former Naval Aviator. This is a great illustration of what we were taughtabout scanning outside the cockpit when I went through training back in the'50s. We were told to scan the horizon for a short distance, stop momentarily,and repeat the process. I can remember being told why this was the most effectivetechnique to locate other aircraft. It was emphasized (repeatedly) to NOTfix your gaze for more than a couple of seconds on any single object. The instructors, some of whom were WWII veterans with years of experience, instructedus to continually "keep our eyes moving and our head on a swivel" becausethis was the best way to survive, not only in combat, but from peacetime hazards(like a midair collision) as well. We basically had to take the advice on faith (until we could experience for ourselves)because the technology to demonstrate it didn't exist at that time.

I think you'll be ok with 1/4". Pretty sure that's what I used. I can measurethis weekend. Slightly different topic: The attach lugs that form the hinge at the top of thegear legs are welded on in a cantilevered arrangement. On the advice of theFAA, I wrapped and welded thin steel finger reinforcements over the top of thelugs and then down onto the gear legs. That gives several inches of welded supportto the lugs instead of approximately 1.5" of welded support in the caseof the cantilevered arrangement. There's a reason I point this out.--------Kevin "Axel" PurteeNX899KPAustin/Georgetown, TXRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________

DanYes the skis are homebuilt, they are nothing more than aircraft ply glued up ina gig to a thickness of 1/2" than coated with epoxy to provide durability andto reduce friction over that white stuff.Made up a set of dolly wheels with a shaft that slips into the axles and a pivotarm that allows the skis to be raised off the ground in order to maneuver theplane in the hanger (dolly visible on hanger floor)You must be familiar with that white stuff in Illinois or not??Actually this past weekend was the first time this winter that there has been enoughsnow to take the plane out, what a blast!!!--------Adrian MWinnipeg, MBCanadaRead this topic online here:http://forums.matronics.com/viewtopic.p ... ttachments: http://forums.matronics.com//files/dsc0 ... ___Subject: Pietenpol-List: Re: Steel LG Lug Thickness

Kevin and Mark, Just for reference, Wag Aero uses .063 steel for the fingerstraps in a similar reinforcement on their Cuby plans. The thicker steel isharder to bend but easier to weld.Skip> [Original Message]
