First try to visualize the end product.
A dowel that is full round for about an inch on each end.
Between those ends, part of the dowel is cliced away so that it has a flat
surface. running most of its length.
I set my table saw blade very low, so that less than a quarter of in inch is
above the table surface.
If this helps, think of cutting a very wide dado in the dowel.  If that's
confusing, forget it.
When I lay the dowel on the table saw surface, and just in contact with the
blade, I can slide the dowel from left to right across the blade, and the
table saw blade with cut away just a little of the dowel.
As I work the dowel further into the blade, it will cut just a little
deeper.  I keep up the left to right motion so that I keep skimming off a
little bit of the dowel, until I have cut about half way through the dowel.
If you can cut less than half that's good, because it will be stronger.
What you need, is to have that side of the dowel flattened enough so that
the nut can fit between the dowel and the inside of the pvc, and still let
the dowel slide in and out freely.
You can do the same kind of cut with a router.  Set the router in the router
table with just under a quarter inch of bit showing.  When you run the dowel
over the bit, you will make a flat side to it.  Again you will want to leave
about an inch on each end uncut.
Now, how can you make that cut safely.
My plan was to put small clamps on each end of the dowel, so that I could
hold onto the clamps, rather than the dowel, and keep my fingers away from
the blade.
This also helps to keep the dowel at the same orientation, so that you do
not end up with a spiral shape to the part of the dowel you cut.
I also set my table saw fence, so that I could not slide the dowel too far
to the right, and lose that one inch of full round.
I also clamped a piece of wood to the left side of my table to ensure that I
would leave one inch of dowel uncut on the other end.
Later I thought of another method.  You could cut two blocks of wood, drill
holes at the same place in each, and slide one on each end of the dowel.
You might need to wedge the dowel in the holes to ensure it does not turn
Then you can hold the two blocks as you slide the dowel over the table saw
glade.  Of course, now the dowel is above the surface of the table saw, so
you will need to raise the blade to the correct height for cutting off just
the amount of dowel you want to remove.
Hope this helps, and if you have any more questions, feel free to ask.
Blessings,
Tom

  Tom: I think I understand the theory behind what you've done here, but I'm
a little confused about cutting the dowel. If I understand how this looks,
there have to be two right-angle cuts, near the ends of the dowel, is that
right? Or, how were you able to cut this dowel with a table saw without
cutting all the way and then flattening the ends as well as the middle part
of the dowl. Also, you said you clamped both ends. I have a cheap table saw,
and if I were to clamp a piece of wood to the table, I wouldn't be able to
slide it the way I think you'd need to do to get a flattened dowel. Did you
do this say, by lowering the table over the blade? Thanks for any
illumination.
