Now that's a big R/T :yikes:
Its probably about as big as you would ever want to go on a Bridgeport.
You will find Y-axis to be a bit limited, but useable just the same. I have a 12 inch R/T on my mill,
and with a chuck mounted to the table, its one heavy bugger. Yours must be well over 250 lbs.
I think the load cap for the Bridgeport is 500 lbs, so you should be fine. I would keep that centred on the table
though. That is a fair bit of weight if hanging off to one side. On the plus side, you have lots of room on the table for work holding :biggrin:
I guess your next purchase will be a small crane, or hydraulic lift cart to move you R/T on, and off your mill.
