My recent post on moving the ram of a Bridgeport style mill http://www.homemadetools.net/forum/m...-machine-65535
motivated me to search for weight details. I found the following list for the J head mill with the large option table. I don't know if the head weight includes the motor or not.
Head - 91 kg.
Ram - 99 kg.
Ram adapter 41 kg.
Turret - 97 kg.
Column - 325 kg.
Knee - 117 kg.
Saddle - 65 kg.
Table - 166 kg.
I hope this data will be of use to those who might have to move such mills, giving an indication of which parts need to be removed if available lifting equipment is inadequate for the whole machine.
I made this a separate thread rather than add it to the ram moving thread to make it easier to find.
