I did take the column off originally thinking It was a necessity after having watched Dr Dflo's video on the old heavy metal kit. But after putting the column back up we found that the slide for the head would come off and on the column without having to unbolt the it. I would say if you are ordering this kit, plan on removing the column but try removing the slide before you you actually loosen the bolts. If the slide comes off without removing the column then it is not necessary. The ball screw will go in without having to remove the column from the base.
Unfortunately I did not weigh the head, I dont have a scale here at home, but it is heavy. It probably weight between 70-80 pounds alone without the motor.
