Hi, sorry I'm not sure if it's the good place to post this request. I'm building a ball lifter, like the orange one available sometime. The path for the balls toward the gear, the motor, the vertical tube, everything work fine.

My problem is the passage from the tray to the path that goes to the gear. Since the path is just large enough for one ball (two cannot be side by side in the path), the hole in the tray is large just for one ball too. This cause a problem because two balls may align themselve over the hole, side by side, and prevent each one from falling in the hole.

If someone have a minute, and the orange ball lifter, could you take a picture of the tray near the path entrance that goes to the gear, so I can see what I can do to prevent two balls from aligning themselve side by side over the hole?

Thank-you very much.
