Hector, we admire your resourcefulness!
I had recent experience working on a "Bush Hog" rotary mower that many of us
are familiar with, that are widely used and widely available. The typical
one attaches on a "three-point hitch" and "PTO" (power take off) of a small
to medium farm tractor. They are about the width of the tractor, sometimes
wider and typically have a single large blade. Particularly the "Bush Hog"
brand is well made and capable of mowing even saplings (trees of up to an
inch or two diameter), in addition to just grass and weeds. This is the
mower of choice when brush and grass have gotten to be tall -- several feet
high. I've mowed brush as much as eight feet high with them.
Getting to the point, there is a gearbox, transfer case, in them that could
be salvaged from old ones, could be found at junk yards, etc., that will
give you a 90 degree turn. It also strikes me these gears could be adapted
to (welded) prop pitch rotators, etc. for that application as well. If you
can find one of these it could give you the 90 degree turn you want. (It
seems to me that finding a different way to mount the motor would accomplish
the same thing but keeping the motor in the orientation you prefer and
making the turn with a gear assembly may indeed be the easiest and best
I am going to start "keeping my eyes open" for old "Bush Hog" mowers with
the idea of salvaging the gear box.

I WILL LIKE TO KNOW WHAT TYPE OF TRANSMITION AND MOTOR ARE THE BEST TO USE
TO ROTATE A TOWER, I HAVE A FEW PHOTOS OF HOMEBREW ROTORS AND OTHER
COMMERCIAL OUT OF MY BUDGET. I WILL LIKE TO BUILD THIS AT LOW COST BUT
HIGH QUALITY , FOR THAT REASON I WILL TAKE MY TIME AND LOOK FOR THE RIGHT
I FOUND HERE IN A LOCAL JUNK YARD SEVERAL TRANSMITIONS WITH MOTOR IN VERY
GOOD CONDITIONS AND GOOD PRICE 100-150 DLLS COMPLETE , THIS ONES COMES IN A
MACHINE THAT WAS USED IN SOME AGRICULTURAL PROCESS. VERY STRONG AND THE
SHAFT IS AROUND 1 1/8 INCH , THE ONLY PROBLEM IS THIS IS MOUNTED
HORIZONTAL. IN THE LEFT THE MOTOR AND THE RIGHT THE LOW SPEED SHAFT , NOT
ABOVE LIKE THE ONE THAT APPEARS IN THE NCJ THAT HAVE IN USE A CONTEST
STATION IN OH0 LAND.
I WILL APRECIATE IDEAS AND YOUR OPPINIONS.
TNX IN ADVANCE
