I have been looking for bevelled gears 15-20" diameter for a large kinetic sculpture for the last couple of months. It's been a challenge. I have tried a number of local scrap yards, gear suppliers, repair shops, with no luck. I am now following some leads from contact at the CR4 The Engineer's Place, http://cr4.globalspec.com/
Thank you to all the people that responded to my inquiry for gears. I am pursuing their leads and have appreciated connecting with their group.
I work in isolation in my studio, and I am finding the internet an amazing way to feel connected in the world wide community.
If anyone in the Calgary area has gears of this diameter please email me!
Thank you,
Geoff
