    Need to find a good wheel alignment IA/A&P for my 180

    Already paid to have it done wrong.
    I am hoping I can find somebody who is a whiz at 180/185 wheel alignment.
    Hopefully not super far from Homer AK.

    Step one, that’s not in the book, (on well greased grease plates) measure from strait edge touching front of tires back to a drain hole just forward of tailcone and see if it’s the same, if not put a spacer in front of tire to space strait edge off tire till equal to other side. This accounts for bent legs and bent gear boxes. Now do the normal measurements. If you don’t do this step and have one leg trailing you will pull to one side of runway.

    I don’t do the actual changing of the shims, but I make custom shims for other mechanics. Remove all old shims before measuring and in one shot I make a custom set of shims in one shot. https://photos.app.goo.gl/1oSPijbAAyJ7B7fs1

    Did it myself using the procedure from Grove. They sell shims and show you how to do it.

    The plane was nosed over years ago and rebuilt. I usually have her on floats so I never fixed the land-gear.
    But she was going all over the place so I tried to get somebody here to fix them during the last annual. They used dollies under the main wheels instead of grease plates. And did not shoot a straight line from the spinner tip to the tail drain hole. Anyway, the port side was super toed out and now it is a little better after reversing one shim. For some reason the IA in question would not continued with the starboard side. So it is still F'ed up like Hogans Goat. Although now when taxiing it only slowly goes off to the right instead of violently breaking to the right like it did before. 30 years ago there was a guy in Biglake who was good at this. But he is probably dead by now.

    What’s the use of the line from spinner to tail? None...

    If it goes to right that probably means right gear is trailing left gear.

    Originally it was DUCK-Footed when I bought it. Both toed way out. So it would go hard right unless you rode the left rudder. Then after 100 feet it would suddenly spring over and try to go hard left. Then it would go back to pulling right. It must have been the gear legs building up spring tension on the pavement..
    Now it gently pulls to the right. And as you can see the camber is off on one side.
    As for the center-line of the aircraft, one old guy I helped used that as a base line. Years ago ( early 90s) when I helped him, we hung a plumb-bob off the nose and one off the rear drain hole or base of the stinger. Then marked the floor. Then we measured the front and back of the tires ( on grease plates) to the center line and back to the drain hole so he could figure out which one was doing what. I do not have a place down here to hang my hoist.

    Alex, why don't you take some fresh Halibut and crab and fly up and visit Mike.

    Alex,
    If you can get Mike to look at it no matter what it costs it is a bargin considering how easy it would be to wreck the beautiful old 180 if you have the "wanta bee" crowd dicking around with it. I wouldn't even ask him how much just run it up to him if he would do it and then you know it will go straight down the runway when you pick it up …………………… how much is that worth when you need to land in Homer in a big Xwind???? PRICELESS.
    Good Luck

    You guys gotta quit volunteering me. Like I said I just make the shims. I haven’t seen my jack for doing installs in 15 years, but I hear it under someone’s house.

    As I told you. My 180 was screwed up. It has been put on it's tail. Please do yourself a favor and read this.. It is not hard. Mine tracks straight and true after I did this. It is not rocket science.

    I guess that will also take into account of a trailing gear leg....

    Probably not but I had removed and reinstalled the gear. It worked with me. Mine was toe in/out.

    It will...

    Different method from cessnas strait edge in-front of tires. This method looks better.

    Was there any consideration taken for the engine offset?
