Kind of depends on how your column is set up. If it's a GM column, or based off a GM column, there are a couple places online that I found with a quick search that will get you at least 1/2 or 2/3 of the way apart.

If it's like mine and was made across the big pond, then all bets are off as to how it comes apart. I do need to take mine back apart to put the wiring and switch back in, but was wanting to leave the extra stuff out during mock up. I can't really recall from memory, but it was a little similar to the GM columns, until you got past pulling the tilt pivots out and then removing the base of the tilt from the rest of the column. I think the 4 screws that normally can loosen up over time that they are talking about in those 2 links, on my column, they screw into an odd notched shape plate that pulls the lower bell or bowl up the column tube against a snap ring. The lower bowl, or bell is an almost press fit on the tube, where I had to be careful about using a rubber mallet or my hand to try and bump/nudge it off once the snap ring was removed. The bottom of the tube had a thick flanged metal sleeve with plastic bushings for the shaft to turn in. Not the best setup, but I didn't have to spend $700 or more for a custom length ididit or Flaming River column. Now that I think about it, there was an inner tube also, in addition to the chrome outer tube. The inner tube was welded to the lower flanged sleeve and the odd shaped plate with the screw holes went in the other end. The lower bowl or bell was on the inner tube, and the whole shebang sort of captured the outer chrome tube, or maybe the lower tilt halve, positioned it. Something like that. I wanted a real ball bearing down on the bottom instead of the plastic bushing, plus, in order to cut everything even, I had to grind where the inner tube was welded to the lower flange, so I could move it up after the cut. I ground down the flange so it would fit up inside the outer chrome tube. I was lucky and found a flanged ball bearing that had the specs I was looking for, so that allowed me to weld the old flange to the new bearing, and then weld the old flange back to the inner tube, which was now shorter. I believe the wiring ran between the inner and outer tube, so the shaft wouldn't rub against the wires. The column, as delivered, had something like a 1"DD hollow shaft for what came out of the end of the column. The I.D. of the 1"DD was 3/4"DD. I was able to cut and flip half the lower shaft so I could use the solid 3/4"DD. I was really amazed at how well everything just kind of fell into place for what I was wanting. For the record, it really is a cheap column though.
Like I said, I was too happy to stop and grab the camera. I could probably take a few this weekend if you think it would help?
