The Flex 940 and Combo 910 are practically the same machine, the only difference are the base clamps. The Flex 865s is really a table top machine on a stand. If the Flex 865s has the same center mount of the Flex 740 it's totally different from the Combo 910/Flex 940. It's kind of backwards in design.
I think it's the disc brake that causes some of the wobble. The screw brake on the Plus 6500 is the same screw brake on the Flex 920. Much more simple in design.
i don't think he was implying that the machine wobbled, but rather that the guy rocked it to and fro and it didn't wobble.
and disc brakes don't cause any wobble, the disc has enough free play on the bolts so that it doesn't affect the turning table at all.
