Made your own coupler boxes?

A question for all of you who have made your own coupler boxes to put
Sergents in what have you used for the pivot? I am about to make new
coupler boxes to replace the incredibly lame ones on a model. I have
designed all the parts I need to make and that just leaves me with the
pivot. All I can think of is some 1/8" Plastruct tube though I wonder
how well it would wear.
