Bridgeport Manual to CNC conversion...

[lucan07]

Just to throw a spanner in the works may be completely irrelevant but on my travels today saw a bridgeport (couldn't tell you the model) converted to CNC, that used original and a 24k spindle slightly different setup to your plan.

The 24k spindle was mounted literally beneath the original in a frame so when changing between spinles he just had a Z offset to consider but apparently with Knee or second Z thats not a problem, frame actually locked into a collet then connected to frame, his spindle was shorter than mine and he lost a fair bit of Z travel but this still left a good amount of travel on Z for what he used the 24k for.

Just thought I would share unfortunately I was out on the road bike (lycra man) to escape idiots for a while so no phonewith me to grab a picture.
