Excellent! Like the way you've encapsulated the slift spring. Wished you could have show a full build with a little more detail, but well impresed! Thanks for sharing, regards, Tony.👍

Thank you. Where can I purchase the lift motors with the gears to keep the lift motor from running too fast? Great build!

Excellent build and excellent video with great visuals and good audio, too!! Thank you lots for sharing some methods!

Which wire is used here and how many millimeters does it have? What diameter do the balls have? Thx
