Here is a picture of a new e27 mast base on Buzz's website:
http://ballengerspars.com/photos/hmbe27.jpg What isn't shown is that a 1/2" thick piece of aluminum is bolted to
the top of the hinged base through the 4 holes in a diamond pattern
you can see. This piece is shaped to fit inside the e27 mast with
just a little slop. Then the mast base is screwed to that piece from
the sides with small (#10) machine screws.
The alternative Buzz described isn't a stock e27 setup (though it is
legal). Instead of the 1/2" plate of aluminum (which requires screws
through the mast extrusion very close to the bottom of the mast), a
box section of aluminum is cut to fit inside the mast and this box is
bolted to the hinged base. Then a single 1/4" bolt is put all the way
through the mast and box section to hold it all together. Box section
size will depend somewhat on mast section, but 2" x 2.5" x .125"
sounds like it would fit the e27 mast well. If Buzz said that is the
right size then it is!
I've never seen this assembly on an express 27 before, so you might
have trouble digging up a picture-perhaps you were discussing a
specific mast base problem with Buzz?

:: Hello,

:: Ballenger explains some sort of tubing (square tubing

:: I need photos to better understand the mod.
