Hello guys, I recently acquired a used Bridgeport mill ( my first encounter) a
friend had outdoors . I managed to get all the parts freed up, even the motor
works. But i've encountered one road-block, the R8 collet i tried in the
spindle seems to be too long. _*_What other type of collet does the Bridgeport
use?_*_ I think this is a J series, here is the serial # J163607 stamped on
the head. A plate attached to the head has drive serial #2J40289. **
