He cant use a 12” arm on the 930 as it is but he can have a standalone arm colum on the outside of the table or use a 3009-R and it will fit the round EMT mounting hole with the sled and base cover removed.
I have 3012R sitting at the back of the table. I want to try FR64s cause of both me having a lonely FR7 cart plus a hassle free instalation. Anyone can help with this particular arm ?
