Not sure how you were planning to tackle this job but i would use a pedestal
drill
or milling machine with the torque tube fully assembled and clamped hard to
the machine tool table.
Hand drilling and reaming will probably lead to disaster unless your are very
lucky!
I would approach it this way -
Match mark all components so you don,t get them round the wrong way.
Assemble the torque tube on the original 1/4" pins and loctite the components on
to the torque tube. Make sure you have the stabilator drive pins aligned port
and starboard, this won,t be an issue if you have zero wear in the assembly
on the standard quarter pins, if you have then align as best possible before the
loctite sets.
Once set knock out the 1/4" pins and set up on the machine tool aligning the
spindle
on your first hole to drill. If you cut the head of one of the original
1/4" pins you can use it as a guide by mounting in the chuck and centering
through
the first hole to drill on both sides of the torque tube.
Clamp your tube firmly and then using cutting compound start drilling in small
steps untill your 1/64" below 3/8". Finally use the reamer with cutting
compound
to achieve the 3/8" finished size.
Repeat for the other three holes and then warm the components to soften the
loctite
enabling them to be removed.
If i was local i would offer to do it for you unfortunately i guess i am not.
Also if this is just to remove slop in the pins consider a smaller stem such as
5/16". Also if your nervous about the work take it to a local machine shop as
this type of work will be straight forward to them, they could also manufacture
some 5/16" pins if you wished to go for that option.
Good Luck
Pat
