Excavator Equipment

When it was time to sketch another heavy equipment, I knew exactly where to proceed in town.  I happen to pass by along St. Roch Avenue two days ago and saw this huge excavator prominently parked at a big development site.

Using the hydraulic piston cylinder as the base measurement for the entire scene, I mapped out the pencil drawing on a two page spread.  Several times I had to reinstate the base line of the main engine.  I found it helpful to bring up the edge of the sketchbook to guide me where to put the lines in proportion to what I'm seeing.  Here's the sketch - a work in progress.  I might come back to it again one day to finish accenting the lines for the post and the power lines, cast shadows, etc.
