Uwe,
It might not be compound or carraige slop. It could be flex in the work,
chuck or tailstock as well. Pay attention to all details. When looking for
something loose. It helps to use a dial indicator on the work and move each
unit with reasonable force and watch for deflection.

I recently got myself a 12" Reed & Prentice lathe which I am running
through the paces.

I noticed when I take a cut and backtrack the carriage I am still taking
another cut. I did not expect that to happen, rather after a cut I would
expect the tool to just barely touch the piece upon return of the
carriage,
but not so here.

Someone said that was a problem with the compound rest but I don't
understand the phenomena at all, where does that "slop" originate?

And what can I do if anything to remedy the situation??
