Scott is looking for an air powered pop riveter.

Scott,  Try Northern Tool.  Select air tools, and type in   riveter.  They
have an air powered one that goes for abt $70.    

(Not connected with Northern) (( just like dreweling (sp?) while looking
thru their website))

    Umm, what's a "tower jack"? I use the Tower*Jack  that is used to
assemble/disassemble Rohn guyed towers but don't know what a  tower jack is
other
than that. Do you mean a jackscrew - e.g. used by one of  the aluminum tower
manufacturers to run it up and down? How are you going to  use it?

        Interesting but I've still  got no idea what you mean. A picture's
worth 1k words.

    Very interesting but not useful. It doesn't do  anything about the
significant design flaws of the Orion mast clamp that ARE  the problems.
None of the
above will keep the mast from slipping.

Hello

I've inherited what I was told was a KLM 40M4. (Not sure if
that's a valid model number.) It needs works and I'm looking
for a manual. An electronic copy would be best but also willing
to pay for a photocopy and mailing (let me know first).

Interested in making this a 3 element (I'm expecting that
4 el will exceed my comfort level at this point). Maybe
it's just a matter of dropping the second director but
interested in comments from those in the know.

thanks for any help.

  Thanks for the reply Steve. I will look through my older photos and try to
find some pics from the last time I completely dropped my tower. This was
about 5 years ago. I also plan on contacting Morrison Tower to get
permission to photograph and measure their remaining pair of tower jacks. In
any case pictures to follow shortly...

I think someone has already mentioned Harbor Freight.  I just had a look
and their air powered riveter at $29.99 looks very  similar to the
$69.99 one from Northern Tools.
