Step 4: Transmission - Step 4 - Assembly
All 3 perspex rectangles were placed 25mm – 30mm parallel to one another, the one without the large hole at the front. The small holes at the top, big hole for motor at the bottom. The threaded rod went through the holes in each corner, the motor through the 2 big holes. The small 4mm rod through the 4mm holes, the longer one through the top (filed if necessary)
Double nuts were used on the threaded rod to keep it all together.
The 40T gear was attached to the motor, the 50T gear meshes with that on the smaller 4mm rod. On the same rod is a 10T gear that meshes with the 60T gear on the longer rod, to which the blades will be attached to.
Note: Washers were used to stabilise gears after testing.
