Yes, Timken-type bearings would also work, they are just often more
expensive
and larger.

Right, just a simple, single-row ball bearing to keep the free end from
flailing
around.

Hi Jon; and others who attempt ASCII art.

The problem, is the inclusion of the 'TAB' charactor in the 'art'.
The action of the 'TAB', is not consistant, from system to system.
DON't use it, use the space bar to move over to where you want the next
part of your drawing.
