First make sure you have to take the table off. Can you run the table
out to the end of the knee and work it around the corner first and then
go forward with the mill? If not then your table removal scheme sounds
correct. Perhaps add some timber (cribbing) to the floor at the bottom
of the steps so you only go down 1 or 2 (or less?) steps and onto
rollers (wooden rollers are best here) and then down to the floor in
several stages from there, removing cribbing as you go forward. If you
can get a good holdback on it to control the forward movement and one
or two husky helpers you can do it easily without the skid.
I would suggest not bothering to take off the head or overarm unless
you're without help. If you're anywhere in my neck of the woods I'd be
happy to lend a hand (100 mi. N of Sac.)
I hope this helps.
