Chris,
=A0
Actually, I made my alignment testing jig using your copper pipe idea.=A0 T=
hat's how I found out what the problem was.
=A0
I really didn't feel comfortable just bolting that assembly in, even with a=
ligned bearing blocks.=A0 The middle of that assembly had about a 3/16"=A0r=
adius "orbit", and would really stiffen up when the outboard bearings were =
tightened in place.=A0 It=A0seemed like I was setting up a four-way fight b=
etween 1) the flap motor, 2) the torque tube flanges and bolts holding them=
 together, 3) the bearings themselves, and 4) the structures holding the be=
arings in place.

Between drilling the holes out and using Tim's pressure realigment method, =
I just may get this to work.=A0 Thanks to everybody for the ideas.
=A0

I used a copper pipe as a guide to get=A0the bearings straight.=A0 After th=
