Reverse Engineering an Existing Product, Part 2: Progress

Image
  After discussing the merits of my three chosen objects for reproduction, it was decided that I should try to reproduce the Stainless steel pocket plane. When disassembled the plane has eight distinct pieces that need to be measured and modelled. The blade adjustment screw is the first part I decided to try to model and I was very pleased with the results I have managed to attain so far. I started with a cross section of the adjustment screw, without the threads for the two adjuster pieces, which I revolved around a central axis creating the body of the piece. I then drew 2 circles at positions longer than the threads and used the spiral command to create a path to model the threads. I modelled the threads away form the adjuster body and then copied them onto it and used the boolean union command to make the adjuster screw one piece. After I modelled the adjuster and threads I proceeded to reproduce the knurling using the flow command to apply a skin of diamond shapes to the main ...

Reverse Engineering an Existing Product: Selection / Tools of the trade

Image
I was initially drawn to materials around my desk to consider for this project.  I found pencils,  pens, a sharpener and a stapler scattered about the area.  This first photo contains two of my favourite stationary tools. A stapler which was my mothers when she was a teacher. She gave this stapler to me in 1982 when I was in grade 6. The second is a brass pencil sharpener that I purchased last year. I find it to be the perfect tool no matter the type of pencil I use it on. I appreciated the weight of the solid brass body, as its weight emanates quality.           The Stapler has many moving parts that would make an intricate and challenging design, but most of the parts are riveted or press fit  together   and do not lend this item to being dismantled. The Sharpener seems too easy but presents complex internal geometry, and many surface textures.  As I thought further about this project and considered what else would possibly m...

Surface Design Study: Design

  The Lernaen Hydra The main character of my surface design is the nine headed Hydra. I choose this mythical beast of nine heads killed by Hercules in the second of his twelve tasks, because  the floor linoleum  sample I found has serpentine twisting figures emanating out from its centre, that remind me of the Hydra. My hydra is based on the  centre three heads of the above image. Linoleum Preliminary sketch This was the starting sketch for this project. The background is a watch or clock face, and the square is a reimagined piece of floor linoleum. The textures I applied in my example come from my own personal watches and an image of another watch. The Sketch is  incomplete because at this point I moved into rhino to sketch the project and adjust as I went. Line Work I also took colour inspiration from two wall murals I found here in Calgary, the Hydra image above, a yellow and white pickup truck, and watch face images. Colorful Wall Mural Flames...
