I chat with Jack once in a while on FB and he is impeccable when it comes to precision. He's finally coming out with a production run of his newest machine the Rotator MKIII. Powered by a maxon 216000 motor. Here are some pics of his machines. 10371372_727635387298740_34630525079207146_n.jpg10383580_727635467298732_3823429421718424536_n.jpg10308246_727635347298744_4166172633506514988_n.jpg10388467_726082600787352_980454216_n.jpg. If anyone is interested you can contact him on facebook by looking up his name or send him a pm here. I wish him good luck on this endeavor. He's been building machines for a couple years and this is his first true production machine based off a design he's been refining. Contact him for pricing and sales.
