• Using Autodesk Inventor, create the following 2D Part sketch.
  • 
• Use 3D Model > Revolve to convert the base profile into a 3D part
• Apply a fillet radius of 0.02“ to the two edges on the top of the gyroscope base

• Step 1 - create a circle with diameter 1.0”
• Step 2 - symmetric extrude a length of 2.25“
• Step 3 - at one end of the post, create a new sketch and draw a circle with diameter of 0.05”
• Step 4 - extrude the circle a length of 0.125“
• Step 5 - either mirror the post end or recreate using steps 3 and 4 on the opposite end of the post.
  • 
• Step 6 - create the pull string hole (diameter 0.063”) at 0.25“ from either end of the center post
• Step 7 - apply a 0.02” radius fillet to both ends of the post

• Autodesk Inventor procedure to create the gyroscope outer ring part
• Step 1: create a 2D sketch on XZ plane of the ring centerline, diameter Ø = 2.65“. Then finish sketch.
• Step 2: create another 2D sketch on the XY plane. Then project the geometry of the Ø = 2.65” circle.
• Step 3: create a circle to represent the ring cross section, Ø = 0.125“. Then finish sketch.
• Step 4: Finally use <b>Sweep</b> command to complete the outer ring

• Complete Gyroscope Wheel. Following is a discussion on how to draw this gyroscope wheel using Autodesk Inventor.
• 
• Step 1 - draw the wheel profile
  • 
• Step 2 - revolve the wheel profile
  • 
• Step 3 - create a new sketch on the wheel face, draw the inner web cut triangle. Finish sketch and then perform an extrude cut.
  • 
• Step 4 - apply a fillet to the web cut
  • 
• Step 5 - copy the fillet to the rest of the wheel using the circular pattern.
  • 
• Step 6 - apply a fillet on the top and bottom of the web cut.
  • 
• Step 7 - Same as before, copy the fillet to the rest of the wheel using the circular pattern.
  • 
• Step 8 - apply a fillet to the rim of the wheel.
  • 
• Step 9 - insert a hole for the center rod
  • 
• Step 10 - apply a chamfer to the top and bottom of the hub using an angle of 17° and distance 0.066”
  • 
• Step 11 - apply a 0.02“ fillet at the wheel hubs
  •
