To lift my mill (pretty much the same model as yours is), I run a chain down thru the column and loop the end around a common 1/2 drive extension at the bottom of the column. The mill will lift almost straight up and absolutely cannot "over-center"...a danger of any "underneath sling lifting " apparatus, the top of the thing always wants to tip out of its harness it seems. Lifting through the center with a suitable rated engine hoist just eliminates all the dangers...and you can do it yourself. My-ownself, I hate lifting stuff with "help around" unless absolutely nessesary...the less hands-fingers-feet targets around the better.
