A 1/8" (#5?) bolt might be OK to hold your hard drive in your computer, but 
it certainly is not strong enough for pinning a mast.  The Yaesu G-2800DXA 
rotators come with a 8mm (5/16") bolt  for pinning the mast.  If you have to 
rely on the mast slipping to prevent damaging your rotator, you should 
strongly consider a bigger rotator.

Hi, Byron --

    What I said was "For a 4L SteppIR, you can also  pin the mast.  Pinning
works for
everything except a MonstIR".

    Perhaps I wasn't clear. You can pin it but it  doesn't seem to help. The
MonstIRs I've pinned have broken the thru-bolt.  I used an 1/8" high grade
bolt - you might have better luck with a bigger  one.

    Of course the problem is that you shunt the  forces down the system and
the next thing in line are the gears. And also of  course if you pin the 
mast,
I'm sure it voids your warranty. OTOH I don't know  personally of any Orion
gear failures.

    Like I said before, your choices are to grind the  Orion clamp to make 
it
work, get one like the one I sell or get a prop pitch.

Cheers,

In the  attached note Steve suggests pinning the 2800 mast clamps for
everything  EXCEPT the antenna I have.
