This is tutorial on making crank shaft. The main problem with making such design is with reading the dimensions on the drawing sheet. Well i have solved it for you. In this tutorial we will go through simple extrusion operation to make crank shaft.

1. Step 1:

   Right Plane>>Sketch.
   

   

2. Step 2:

   Draw a circle of 120mm and 4 holes of 12mm at 42.5mm from origin.
   

   

3. Step 3:

   Extrude it by 16mm.
   

   

4. Step 4:

   Right face>>Sketch.
   

   

5. Step 5:

   Draw a circle of 50mm dia.
   

   

6. Step 6:

   Extrude it by 40mm.
   

   

7. Step 7:

   Right face>>Sketch.
   

   

8. Step 8:

   Draw this profile.
   

   

9. Step 9:

   Extrude it by 22mm.
   

   

10. Step 10:

    Right face>>Sketch.
    

    

11. Step 11:

    Draw a circle of45mm at 40mm from origin.
    

    

12. Step 12:

    Extrude it by 35mm.
    

    

13. Step 13:

    Right face>>Sketch.
    

    

14. Step 14:

    Draw this profile.
    

    

15. Step 15:

    Extrude it by 25mm.
    

    

16. Step 16:

    Right face>>Sketch.
    

    

17. Step 17:

    Draw a circle of 45mm dia.
    

    

18. Step 18:

    Extrude it by 35mm.
    

    

19. Step 19:

    Right face>>Sketch.
    

    

20. Step 20:

    Draw this profile.
    

    

21. Step 21:

    Extrude it by 22mm.
    

    

22. Step 22:

    Right face>>Sketch.
    

    

23. Step 23:

    Draw a circle of 45mm.
    

    

24. Step 24:

    Extrude it by 45mm.
    

    

25. Step 25:

    Right face>>Sketch.
    

    

26. Step 26:

    Select this face and click Convert entities since the profile is same.
    

    

27. Step 27:

    Extrude it by 22mm.
    

    

28. Step 28:

    Right face>>Sketch.
    

    

29. Step 29:

    Convert the circular edge.
    

    

30. Step 30:

    Extrude it by 35mm.
    

    

31. Step 31:

    Right face>>Sketch.
    

    

32. Step 32:

    Convert this face since the profile is same.
    

    

33. Step 33:

    Extrude it by 25mm.
    

    

34. Step 34:

    Right face>>Sketch.
    

    

35. Step 35:

    Convert the cirular edge from 4th extrusion.
    

    

36. Step 36:

    Extrude it by 35mm.
    

    

37. Step 37:

    Right face>>Sketch.
    

    

38. Step 38:

    Select the 3rd extrusion face and convert entities.
    

    

39. Step 39:

    Extrude it by 22mm.
    

    

40. Step 40:

    Right face>>Sketch.
    

    

41. Step 41:

    Draw a circle of 45mm dia.
    

    

42. Step 42:

    Extrude it by 145mm.
    

    

43. Step 43:

    Right face>>Sketch.
    

    

44. Step 44:

    Draw a rectangle of this dimension with one point coincident on the circular edge at a distance of 4.5mm.
    

    

45. Step 45:

    Extrude cut it by 100mm.
    

    

46. Step 46:

    Right face>>Sketch.
    

    

47. Step 47:

    Draw a circle of 28mm.
