    Shim stock on one side of bolt

    Or braze it up and team it back to size is better

    I wonder if anyone tried using the flap & aileron block STC’d repair there?? Same size hole....

    More info please. Is the play in the torque tube? In the bolt through the stick stub? Or just loose cables?

    When you push the stick from side to side, does the bolt stay stationary as the stick moves? Or does the bolt AND the stick move?

    Too bad you guys can't throw out that 1940's technology with something modern like this. Have it in my Cub and it is perfect--absolutely no slop.

    Perfect timing for me. I'm about ready to start working on my control assembly. I like that design.

    I replaced the bolt that goes to the ailerons and it was worn and beat up. added a washer and tightened, removed one spacer on the tube, then went to the front stick and the pivot bolt was rusty and worn, replaced that one and greased on assembly tightened as needed.
    Wow what a difference it made in the take up of the sloppy of the stick

    You'll need to find out if the wear is on the bolt or in the bushings in the stub. I would just replace the bolt anyways while you're in there. If the bushings in the stub are worn the choices are; replace it, or build up the worn bushings. Replacing is self explanatory. Building up the bushings will mean either having them welded up and then reamed back to size OR reamed to a larger size and then press in bushings that will have the correct ID to hold the bolt. Going to have to be your call, but you should talk to your A&P before you decide.

    There’s no replaceable bushing there. It’s a welded tube.

    Nothing wrong with an NAS or close tolerance bolt for this. But do some checking to see if a new bolt will completely fill the bushing. If the bushing wear is minor, the new bolt will work well. If the wear is bad, the new bolt will help but not solve the issue.
