Yes.

No. There are 16 splines, and the axle joiners come in increments
of 360/16=22.5 degrees.

If you mean the single angle beam (http://www.peeron.com/inv/parts/6629),
that angle is related to a 3/4/5 triangle, so that the
longer side becomes the 5-side of the triangle, and
the shorter side extends the 3-side.
It's ca 127=180-53 deegrees IIRC.
#4 is 135 degrees.

You can make a circle out of 16 #3. With more #3 you can make
other waffle-like shapes
(e.g. take 6 quarter circles and alternate direction),
it's a little like the 3D equivalent of scribbling.
Put in two #6 in the right places and you get a heart :-)

| Oops. It looks like in your list you exchanged the labels of #3 and #5. And it occurs to me that the splines had to be set so that the half bushings could be pushed together and lock when on the same axle. I would have to take a look to see if that (...)
