[TowerTalk] Yaesu G-2800DXA

[Roger (K8RI) on TT]

As always, When working with tools and metal which can have sharp 
edges:  Wear proper clothing and eye protection.  Gloves are not 
recommended around power tools! If you must wear leather gloves, be 
extra vigilant around power tools. Moving tool bits and pieces grabbed 
by tool bits really have an affinity for gloves which usually take body 
parts with them instead of sliding off.

Can't a 25G accessory shelf be drilled to take the rotator?

The cut out in the accessory shelf wasn't quite right to allow all bolts 
for the Yaesu thrust bearing so I used an Aluminum plate large enough to 
take the bolt circle in the accessory shelf and the Yaesu bolt circle 
for the thrust bearing.  Could something this simple be used for the 
rotator?   The 4th bolt could possibly fit into the off center cut out 
in the shelf?

If the accessory shelf can not be drilled to take the rotator or the 
simple adapter plate:

A complete adapter (accessory shelf) can easily be made, typically they 
may require a metal plate, 3 short pieces of angle 1.5" X 1.5" X 1/8th 
inch, or just 1 X 1 X 1/8th inch and long enough to take the u-bolts 
like those in the accessory shelf.  2 or 6 U-bolts or saddle clamps a 
drill press. (clamps and a variable speed had drill will suffice, but 
the press does a better job. Usually safer too)  The angle can be 
welded, or bolted on.

The plate can be 1/4, or 3/8ths inch Aluminum. The angle can also be 
aluminum. I'd use something thicker than 1/8th inch in that case and 
just bolt it all together.  Use good Al, not the soft, cheap stuff.  
Besides being stronger, it's much easier to drill and cut.

I don't remember the base of that rotator, but you might need a hole saw.

As you will need the metal, go to a metal shop, show them what you want, 
and most metal shops can make one in short order as they are so simple.  
Costs vary widely.  When I was in my supplier's shop the other day, they 
were making a rather large rerod reinforced tower base for a local ham.  
The did in an hour or so, what took me weeks working with one hand, 
leaving me thinking, "Why didn't I have them do this?" <:-))

Cut the metal plate so the flat sides just fit inside the tower. The 
points? Cut them off square so it'll look just like the flat part of the 
25G accessory shelf.  Besides, it won't fit until after you cut those 
points off
As adapters are simple (many ways to skin a cat  Apologies to my old  
"used to be" tom cat) They only take a "little" ingenuity and not much 
in the way of tools.

73 and work safe!
