I am talking in terms of a
light cut on a stiff aluminium bar between centres.
That assumes your tailstock is dead nuts on. If not you're going to be
trying to compensate for a mix of tailstock + bed errors. If you use the
bar unsupported there are flex issues. Having said that you always get
some flex in the work so maybe it is a good thing that the test bar
flexes slightly...
When I was playing with the head alignment on my Colchester I used a
large chunk of Delrin bar and a very sharp cutter. The bar was pretty
stiff and cutting forces were low.

This is also true. But that test bar costs money too.
It can stay in stock as useful material. I am talking in terms of a
