Using that piece in the four possible different allignments, you can place
TECHNIC rotor blades at twelve different angles around the central core of • the
screw.  Unstrengthened stud-only connections don't sound like they're • going to
be sturdy enough to handle rough work like gobbling snow up, but TECHNIC • pieces
might give you the grip you're looking for.

I was probably not clear on this point. I HAVE made a version that just
trows the snow forward. Se this picture at Brickshelf:

There are actually small snowblowers that works like this, and this
construction was easy to build so I started there. But the problem with this
design is that it is only good for a small amount of snow, and for a small
yard. When you only trow the snow forward as you go forward with this type
of construction, it will at the end be too much snow for this to work.

What I was after is two screws that brings the snow to the center where
another fan is located, this fan is the one that trows the snow into the
air. This is how the larger snowblower is working. Its those two screws that
I have a hard time making, partly because it has to be usable and partly
because of odd angels.

Another possibility might be to rework your existing design with 2x6 • TECHNIC
plates radiating out from the core, linking them together with the 1x4 • hinge
plates, and filling in the gaps between TECHNIC plates with tiles.  The • first
problem with that idea is figuring out how to lock the screw around the • central
axle without interfering with the next TECHNIC plate.  You might have to • space
your blade sections apart by another plate's thickness to allow you to • lock them
into position.  The other problem that you'll have is that your radial • spacing
will be thrown off by half a stud, which is going to affect how many • degrees
there are between each blade section.

Anyways, that should at least give you some new ideas to work with.

Thanx, I'll give it a try...
