[TowerTalk] Yaesu GS-065 Thrust Bearing 25G installation help needed

[Clint Talmadge]

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.

  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!
