Default rudder rod end bearing measurements

on page 8-18 in the main manual the measurements are these:
Top: 51/64
Middle 63/64
Bottom 1 3/64
I tried to use these measurements but the top is too close , did you use these measurements or did you use a different?

Default Start there...

I used 51/64", 59/64" and 1 1/16" as specified in DWG 7, Revision 5 (R5 - 2/25/03) and then adjusted accordingly to get it to fit.

A twist or two of the bearings will make your cutting with a laser overkill.

Is the rudder counterbalance hitting the VS skin? That may require some trimming of the skin.

The thread pitch on those rod end bearings is 1/32", so just a half turn will give you 1/64" more or less. Get the top and bottom in and moving smoothly, then figure out where to set the middle one. You also may have to press on the forward edge where it is rolled to get the necessary shape that won't rub on the aft VS spar. Lots of springback in the rolling, so give it a good massage with the palm of your hands and make it into the shape required.
