American chopper s Oil tank Chain Pedal

1.Oil tank

Procedure:

• Rename front plane as midplane for reference.
• Draw a horizontal construction line of 230mm towards left.
• Add two points one on the origin and one above the origin at a distance of 146mm make sure the above point is vertical to the origin.
• Select dynamic mirror entities option and start drawing a vertical line of 50mm at the end of the construction line and draw a line-up end to right move the cursor back to the end of the line to start a curve and join that curve to the origin.
• Ctrl select the centre of the arc and construction line and make them coincidence.
• Ctrl select the inclined line and the point vertical to the origin and apply coincidence.

• Extrude the sketch 170mm in direction 1 and 10mm in 2nd direction.

• Now select midplane and draw sketch as shown in fig.

• now exit the sketch and extrude through all in both directions with no merge result.

• Now apply combine command.

• Apply appearance painted car, Siena.
• Fillet all the edges with 10mm radius.
• Apply fillet edges with painted white.

• Finally, apply shell of 3mm radius.

2.Chain

Procedure:

• Rename front plane to midplane chain, top plane to centre plane, right plane to front plane for references.
• Select midplane and draw a horizontal construction line of 650mm from origin to right from there a 147mm vertical line downwards.
• Draw a circle of diameter 289mm origin as centre and 147mm dia at the endpoint of the construction line as centre.
• Using 3point arc draw the arcs as shown in sketch make the relation between arc and circles as tangent.
• And give the dimension as in the sketch.

• Select the midplane and draw two throw away sketches so we can save the blocks externally.
• Create a 15.3mm horizontal construction line and draw 2 circles of 8mm diametre and draw another two circles of dia 12mm and draw 3pnt arcs ensuring not to snap quadrants, and apply tangent relation with circles on both top and bottom. the radius of the arcs is 28mm radius. and trim out the required parts.save as (chain link 2).

• Draw one more 15.3 horizontal construction line and draw two 8mm diameter circles and using slot select the centres of the circles and give 5.5mm radius save as (chain link1).

• Now save these two sketches as blocks, we can save by choosing tools, blocks, make block and save them as chain link 1, chain link 2.
• Now exit the sketch and select midplane and insert block by selecting tools, blocks, insert block and navigate the blocks we created and insert them.
• Place the chain-link 2 at the vertice where upper sprocket meet the upper arc coincident the other circle of the block to the path.
• Now ctrl select the chain link 1 circle and chain-link 2 circle and add concentric and coincident the other circle of the chain-link 2 to the path.

• Now exit the sketch and extrude only first two circles with midplane 25mm.

• Now again select the sketch 3 and extrude and clear the counters and select the regions to extrude and don\'t merge the results and offset this extrude to 9mm.

• Exit and again select the sketch 3 and extrude the required region and extrude 2mm with no merge and select option vertex and select the inside vertex of outer link.

• Now apply fillet to the end of the pins with 0.5 mm radius.
• Now using curve drive pattern select the extrudes we created and select upper arc, maintain the distance 30.26 and number of instances 20.

• Now insert 2 (chain link 2) blocks and 2 (chain link 1) block.
• Select chain link 1 and make concentric to last extruded plate and coincident end circle to the path and select the chain link one make concentric to chain link 2 and coincident to path and repeat the same to other blocks.

• Extrude all the pins except the last one with midplane 25mm.
• Extrude the required regions as we have done previously and make curve drive pattern for the smaller circle with 4 instances.

• Repeat this procedure for the lower arc with 23 instances and larger circle with 16 instances.

• Delete the last inner plate and select the two pins edges and convert entities and make a slot of 5.5mm radius and extrude 2mm and select the vertex and select inner part of outer link and opposite direction.

• Select all the pins and its fillets and make them as one folder. ensure al the pins in one folder.
• NOw select all parts except pins and mirror them about midplane.

• Apply chrome finish to the chain and save.

3.Pedal

Procedure:

• Select the front plane, draw a midpoint vertical construction line from origin and select the midpoint.
• Draw two horizontal construction lines on both ends of the vertical line towards right. now give the vertical dimension of 35mm.
• Draw two horizontal lines from the ends of the reference lines and make them equal, now give dimensions for the this line from righ end to the origin as 75mm.
• Now draw 3point arc from left ends of the upper and lower lines, make tangent relation between arc and lines and arc and vertical reference line.

• Draw a line from upper endpoint to lower right-hand side and another line from lower endpoint to lower right-hand side and make these lines parallel as give dimensions as shown in sketch.

• Draw a horizontal reference line at the top right of and any length, and give dimensions, vertical distance is 84mm and horizontal distance is 255m.
• Draw a circle of 16mm diameter on the centre of arc and another equal circle from a horizontal centre to centre distance of 47mm.
• Draw a circle of dia 18mm at lower right side and a circle of dia 15 on upper right side.
• maintain the distance as shown in the sketch.

• Draw two splines as shown in the sketch and give dimensions as it is.

• Apply a fillet of 60mm for the upper and lower points in the sketch, and exit the sketch.

• Extrude the entire sketch even including the circles of 8mm width.

• Now again select the sketch and select the first two circles and extrude them in opposite direction with 20mm length.

• Add a fillet of 1mm radius for the two faces of the body.
• Select the top plane and draw a vertical reference line from the midpoint of the second circle to the other edge of the body.
• Draw a sketch as shown and give dimensions and revolve it along the reference line.

• Insert a dome of 3mm to the revolved body, and fillet it with 1mm radius.

• Now select the first sketch and extrude the smaller circles from the surface with 100mm distance.

• chamfer the 18diameter extruded circle with 16mm and 9mm and 15 diametre extruded circle with 16mm and 7.5mm.

• Select the surface and sketch, now select the 18 diametre circle and offset it for 2.5mm do the same for 15mm dia circle.
• Select the further stop of the foot pedal and offset for 2.5mm.
• Extrude this circles with 2mm width with an offset of 20mm, apply a fillet of 1mm for this extrudes.

• Using linear pattern select these extrudes and make a patter with 4 instances with a spacing of 20mm.

• fillet the remaining edges and save the part.
