If i have seen that before to install all rib's and fairing on vertical .i've probably welded an extention to this bushing???

Yes, as long as you could keep it straight.
Maybe thread a new bushing onto an "all thread rod" and then thread the "all thread rod" into the existing bushing to align the new extension piece. Then use a sleeve over the old bushing to the new bushing for the actual welding so you are not welding the "all thread rod" in place. The "all thread rod" would just keep everything perfectly straight for the weld between the sleeve and the old and new bushings.
hi guys, the utube video is great help to see the problem. for what ever reason the threaded post is to short, but being where it is I would not bandade the repair.
I would drill out the stub and fab another and clean the area around the hole and weld in the new one. use the rudder with the rod end screwed in the new post to get the alinement right then tack weld the post and disassembal the rudder from the frame to make a good weld on both sides.
it not as big a job as it looks like and is well worth the peace of mind even if you had to get a welder to come to you. Make sure you use 4160 aircraft grade welding wire. hope this helps.
Ya this help...but...i know this is the perfect repair..for doing that i need disassembal the fairing before make the job...and after that my rudder stop dosen't work( look the video)... So i need to make some work on that to...
I just look for maybe a simple solution...
I have a classic fuse but couldn't find a picture on my project that shows the bottom hinge well; this is the closest I have. Have to agree, looks like the tubes are missing or were just cut off. On the bottom the tube is normally pretty long.

Thank's napierm for the pic.....
And one thing....i dont think the bushing were cutting because the rudder stop work with short one...
The rudder stop is an easy fix. It is not too uncommon that a builder files too much off. When I was building almost 20 years ago the factory recommended riviting .040 inch thick 4130 plate on top of the too short stop as the fix for that.
I agree with Jamesmil that you need to make the proper repair by welding in new bushings.
The fairing will pop off easier than you may think.
if someone with and uncovered Classic IV tail could take picture with measurements for you a welder would have no problem fixing it. If you can't find on to get the measurements off the Kitfox factory I'm sure will get you that information.
