Odd that this post should come now. I was on my way to the garage where I have
my 25G top section laid out across the bed of my pickup to redrill the top for
my Yaesu GS-065 thrust bearing. Here is my plan.
Use masking tape to layout the pattern.
Scribe the center line between opposing pre-drilled (TB-3) holes I can see
though the Blue Painters tape where the holes are so getting it centered was
easy.
>From the intersection of the two lines (center of the top plate mast hole)
>measure half of the 85 mm center to center distance as indicated in the Layout
>Drawing for each of the 4 holes
Mark and drill using the center line I scribed and the distance I measured.
I will let you know if I run into any other problems but that was the only way
I figured I could maintain the center of the bearing on the center of the tower
top.

Subject: [TowerTalk] Yaesu GS-065 Thrust Bearing 25G installation help needed
Has anybody sucessfully attached one of these to a Rohn 25G flat top section?
The mounting holes are on a small enough diameter that two of them are
partially in the hole through the top plate.
I guess some quick fabrication is on order here, but hearing how others have
done it is helpful.
Please reply direct as well as to the list.
Thanks!
