Perhaps OP ment a version for long fibre dubbing brush? If so, the basic construction is similar, but you have to have more room for spinning, i.e. the spinning must be done in air, without the supporting base.
Hope, speed and wax - those are my tools handling CDC. I never ever split the thread, always using dubbing loop and magic tool (or bulldog grip). Just rinse & repeat, success might be around the next corner!
I did a search behalf a friend regarding Anvil Atlas earlier this year, and it seems that the vise manufacturing is not under the Anvil brand anymore. Vises seem to be the same, just different marketing name.
