REFLECTOR: Main Gear Alignment

[nmflyer1 at aol.com]

Dave, 



I wanted to use grease plates but the local real estate lady doesn't like me stealing her signs :)? I tried something a little different. I put down some 4 mil plastic, poured a couple tablespoons of oil in it.. then put down another piece of plastic. You're right. It makes the gear relax into an unloaded condition right away. I'll try the laser thing since I have one. I noticed the I-beam along the side of the tire is more stable at midpoint, but it has a different measurement than down at the bottom. This is probably because there isn't a lot of extra weight in the plane at this point (just engine panel wings and such). I checked today and still had 7 degrees of kick down at the axle. 



Thanks for the input.? Kurt

Another thing to note when setting the toe in.? I've use greased plates so there is no drag on the tires when checking for toe in.? Take two pieces of aluminum sheet about?1.5 ft square and put some grease between them.???Then set the main gear tire down on it, with out changing?the aircraft center line ?When?you set them down on the plates it will always move to the same spot for alignment.? The toe in our out shouldn't change while on the plates, only the in and out from aircraft center should change because of weight.? Just a thought when you are checking. I keep a set in the hangar for any plane I'm checking for alignment.? I also use a laser up against the outer wheel half instead of a long straight edge, works great. 

Dave
