Homemade Roots Blower: Almost done with the design

All i need to do now is print out the drawings and cut a prototype out of plastic or some type of hardwood.

I think my next few posts will be the drawings/blueprints of the individual components. 

If I make this out of wood I would probably just print out the drawing, glue it onto a block of wood and jigsaw out the profile of the part.

If I am to use this as a supercharger as originally planned, this would need to be made out of aluminum at least... as I'm sure gasoline and wood does not mix well especially if I am trying to keep close tolerances on the wood.

DIY Roots blower: Blower case and animation

So my previous posts was about blower rotors and how I might make them, now I get to put those rotors into a case. It is a rather simple case, but I am trying to make the construction as simple and straightforward as possible when I start making it out of wood later on. This is a primarily designed as a kind of DIY home made supercharger, not something you would bolt into your car.

And this is how it looks assembled

Since I have it all assembled, might as well make a animation of it...
