ashish gavali from compton,il
incredible value
great for robotics or any prototyping. you can get the spined shaft from matex gears online for $9. you can grind a flat on the appropriate size rod for the output and its good to go. depending on application should have a bearing sleeved into one of the shafts to reduce slop. brand new these gearboxes are $50. check lotus creative innovations online for a video of a device cleverly using this gearbox.
