MK elevator misalignment (part 2)

[VicenteRC at aol.com]

I use the old "Y" push rod method as recomended in the Focus.  You will need to supports in the front and the back.  I use a real carbon rod (not the Dave Brown is not stiff enought).  In the front and the back I use 1/8" carbon rods to MK 2.5MM ball bearings.  The inrerface between the 1/4" carbon rod and the 1/8" carbon rod are attached with is small pieces of metal wire all glue with JB weld.

Not sure if clear enought.  Basically is the same system we use years ago but all is replaced with carbon rods and links are all ball bearing.
