Untested Compressed air Turbine V1

KEEP IN MIND THIS IS A PROTOTYPE AND HAS NOT BEEN TESTED YET.
All you need to assemble this is a drill bit (plus drill), Pipes or tubing close to the same size as the drill bit, superglue (or other glue), and a 608 ball bearing. The inner diameter of the hole in the second gear is 8-9 MM and you can use any 3D cad software to make other parts to go with this model. Keep in mind the holes can not be larger than 9 mm in diameter. It is highly recommended that you sand the parts a little, but it is like driving a car with your feet, not a good idea. Another thing you may want to do is assemble without glue first.
ASSEMBLY
To assemble drill two holes in a 90 degree angle to each other, but be careful not to drill directly in the center of the casing. Then insert the tubing or pipes and glue them in place. After which you can slide the 608 bearing onto the rod of the turbine and glue it in place, also being careful not the glue the bearings or outer wall. then insert the bearing and rod into the casing and glue the outer wall of the bearing to the hole. Put the lid on and blow air through one tube. If it spins you can proceed to glue the gear onto the rod. The lid stays unglued for maintenance or small adjustments you may want to make later on.
