Step 07
The Split Lock Washer

• A split lock washer usually has a hole that is about 75 percent of the outside diameter. Get a copy of the master cylinder. Duplicate the top ellipse and use the Property Bar to reduce it.
  Drag the bottom up to within 0.60 inches of the top surface.
• Dupe the hole ellipse and move it down the same dimension with the Property Bar.
• Use the Shaping Docker to apply an Intersect command.
• Duplicate the result and put it aside.

Step 08
The Split Lock Washer – split centered

• Create a rectangle 0.75 inches wide by 3.00 inches high. Center horizontally and position vertically as shown.
• Trim the rectangle from the bottom edge.
• Combine (Ctrl+L) the outside and inside top ellipses and trim the rectangle from them.
• Delete the rectangle and adjust the nodes of the inside surface as shown.
• Select the top surface and apply a trim to the inside edge. Combine everything.

Step 09
The Split Lock Washer – split off center

• Go back to the dupe from step 07. Create a line approximately as shown and apply a contour of 1 step at 0.35 inches and position as shown as shown.
• Separate the contour and delete the line. Adjust the nodes with the Node Edit Tool so that they exactly meet the top outside line at the position shown.
• Trim it from the bottom edge.
• Combine (Ctrl+L) the outside and inside top ellipses and trim the contour from them.
• Delete the contour and adjust the nodes of the inside surface as shown.
• Select the top surface and apply a trim to the inside edge.
• Create the rectangle to represent the cut edge, convert to curves (Ctrl+L) and snap into place. Combine everything.
