I can't remember the tube dimensions now but when I put sealed bearings in my slimline featherbed single I measured the column diameter, chose some stock steel tube to give clearance to both the column and inside the frame, making sure it was thick enough and engaged the inner race. Then cut & filed it to length as previously mention in this thread (measure upwards from the installed lower bearing... etc, etc.). Just made sure it was a bit (precision!!) too long, otherwise fitment of the tube is pointless.
From memory (fading) it was 30mm NB, 5mm wall tubing, but please check.
Also take care with squareness of ends if using hacksaw/file, as I did. If you have access to a lathe - no probs!
Hope this helps
Cheers
