I am trying to finish up some unfinished business with my Clausing
6913 lathe. This is my question #1. Do I really need to set up a
coolant system on it? I have plenty of parts and bits for it, it will
not cost much, but I question its necessity. This is just for shop use
to fix stuff up, not for production.

Depends on what you are doing, but I use coolant a lot. It makes a big
difference in surface finish and precision.

You will want splash shields - it can be messy.
