I have a 9" Southbend lathe, which doesn't have a T-Slotted cross slide. I keep thinking about fitting one (they are widely available as the Boxford sized ones fit). Things like being able to mount a rear tool post, easily mount special toolholders, easily use a tool height gauge, etc, etc seem apealing -plus so many "special" setups can be done. So the question to people with this luxury is whether it's as good as it seems, and if it's worth the expense (about £120 I think).
Regards
Kevin
