Modelling the oil tank chain drive and foot pedal of an American Chopper in solidworks

1. modelling the oil tank

Steps-

1. select front plane.
2. select sketch geometry and draw a construction line from the origin to the left.
3. Sketch a point 146 mm vertically above the origin and put a relation.
4. highlight the horizontal contstruction line.
5. from the left point draw a line 50mm, and another line at an angle towards the right.
6. Draw an arc from the end of the last drawn line and intersect it at the origin.
7. Now we are going to select the center point of the arc and make it coincident with the horizontal construction line.
8. Now make a coincident relation with the construction point in step 3.
9. make sure the sketch is fully defined.
10. Now extrude the sketch 170 mm in direction 1 and 10mm in direction 2, both being blind.
11. Start a sketch in frontplane and draw a vertical line from the origin with L=166mm.
12. From the origin draw an arbitrary line that does not make any relation with the left edge.
13. Then from the point join the left edge without making any perpendicular relation.
14. From the top left end of the drawn line, draw a spline with a point somewhere in the middle of the part and intersect it at the vertical line, we will now dimension and define all arbritary points and lines.
15. Make an angle of 92.5 degree with the vertical line and arbirtary line, now apply dimensions to the bottom line making it 215mm(make sure you are adding a horizontal dimension and not a vertical one.
16. Apply a vertiacal dimension between the point on the spline and the origin.
17. Taking the same point as in step 16 make a vertical dimension between the point and the origin of 107.5mm.
18. Now dimension the lenght between the upper lefthand point and the origin with a size of 42mm, make the sketch fully defined.
19. Apply extruded boss and through all in both directions, fillet the entire border and use shell feature to make the solid body hollow with 0.7mm dimension.

2. Modelling a Chain

• Select the front planne and make it perpendicular and start a sketch.
• Draw a horizontal construction line from the origin that is 650mm, at the end of the line draw a line vertically below ie 147mm.
• Draw two circles one at the origin and another at the the end of the second vertical construction line.
• Draw two three point arcs making tangent relation with both tthe circles. Trim the necessary entities to get the desired path.
• Now on the front plane sketch two chain links and make them a block and save them for frequent usage.
• Now make the links co inciddent to the line.
• Extrude the pins one by one and deselect merge result with length 19mm.
• Now extrude one chainlink from the midplane with thickness 2mm and off set it by 9.5mm. Now extrude the second link from the vertex, reverse the directtion and deselect merge results for tall the extrudes as it becomes a problem later while we are patterning it.
• Now pattern the boss extrudes using path driven pattern with the path being the chainlink path and select the bodies ie pins and the two links.
• Now repeat the process to get the desired product.

3. Modelling a pedal

• Draw the profile
• Extrude
• Make Dome
• Use linear pattern

And follow all the steps in the drawing.
