Picture of $1 GearPuller made at Techshop.ws
I couldn't pull a pulley/gear off a scratched motor shaft and I couldn't find a puller in nearby stores.

So, I made this simple gear puller at the TechShop.ws in Menlo Park, California.

thanks a lot , you are a friend in need!!! i will make one immediately
i am a electronics technician and frequently require one puller for small motors, even though commercial pullers at hands this one is easy and smart!
very useful instructable. how do we ensure that those pesky stuck gears come off before the threads give off?
