Step 1: My Wooden Gears.
My gears range in diameter from 63mm (22 tooth), 121mm (44 tooth), 162mm (60 tooth), and 275mm (105 tooth). The 3 smaller gears have a 22mm center hole for a 22mm(OD) X 8mm(ID) bearing, and the larger gear a 28mm hole for a 28mm(OD) X 15mm(ID) bearing. They are laser cut from 15mm and 12mm plywood board, the cross-grain of the plywood giving the teeth extra strength. The laser cutter does burn the sides, though not enough to effect the performance of the gears. With the burnt edges and my black backboards, I like the look of them. I sand and give each of them 3 coats of clear gloss enamel.
The motors which power my work come from old VCR's, and I will go into detail on those another time. The main image shown here is my very first set of gears, which had a smaller center hole. The other images show the works from the video at various stages of construction.
Step 2: My Designs.
Step 3: Summary - Why Art?
The simple answer is that it is what I was trained to do. I have no formal training in engineering, just a love for it and a love for art. Combining the two was a logical choice for me. Obviously my works serve no practical engineering purpose other than for visual enjoyment and to entertain, for me they are much more art, rather than machine. If anyone is interested in seeing more of my work, there are plenty of others to watch on my YouTube page - http://www.youtube.com/user/MechanicalSculptor
This article serves as an introduction to my work, and I will upload more detailed articles on the practical aspects of my creations in future. Thank you for reading/watching, I hope you enjoyed!
