Subject: An interesting idea for a spider

Jerry Armstrong, one of the more innovative members of our local
astronomy club, The Rose City Astronomers, came up with an interesting
idea for a 4-vane spider.  You need a 3/8 inch or so bolt, maybe 1 1/2
inches long, a couple of nuts, and some of that steel strapping tape
used for crates.  If you're not familier with it, it's maybe 3/8 or 1/2
inch wide and very flexible and strong.  The wider you get the better.

Split the bolt in half lengthwise though about 2/3 of its length.
Screw on one nut, thread two pieces of the strapping tape through the
slit, and screw on the other nut.  Bend the strapping tape into two 90
degree v-shapes.  That's it.

How you secure each end of the tape to your tube is up to you, but it's
easy enough to split a 1/4" bolt, drill crosswise through it and the
end of the tape and then pin the two together.  Run the bolt through
the tube.  The secondary holder screws onto the bottom end of the 3/8"
bolt.

Bad ASCII art:

           \     /
            \   /               
             \ /
            (|X|)
             / \
            /   \
           /     \
          /       \
</pre></html>

The spider has a couple of very nice features - it is simple to make if
you are resonably competent with a hack-saw and it can be tightened
very tight so the secondary won't wobble around.
