Thanx for the photo.
Well, I have tried this and it works fine for slashing in the snow and
trowing it forward, but it does not work as a screw, and the snow only get
stuck between the "tooth" after a while. And I only have 10 of those 3-armed
liftarm/propeller blade.
I think the reason for not working as a screw is because it is not "smooth"
enough and there is to little room between the "blades". But maybe I can
make larger gap between them and fill the gap with something else??
I'll also tried with the 1/4sircle liftarm:

This works a little better but will get stuck with snow after a while. Need
more angled construction in the "blades"
I have compared with the "real" stuff, and those rotating blade is actually
rotating slowly. The construction with the propeller blade and 1/4 sircle
liftarm, works best in higher speed. And then it mostly throws the snow
forward until it is totaly clogged with snow...
I dont have a digital camera for the moment, so I cant put photos of how
these constructions work in the snow.
Until now the only one that transport the snow sidewise as I like it to do
is my first screw-construction. And the size is no problem.
I think I have to try with larger construction to get this wierd angel and
spiral form possible.
Good works people. It's good to see that I can trow in a idea here and get a
good and quick respons to it :)
