Are DROs worth the money/trouble
I've been looking at DROs again.? Seems I go through this exercise every six months or so. Wanted to bounce off the conclusion I always seem to come to and see if you guys have a different opinion.

Re: Cutting oil what do you use?
I use STP oil additive when I need an oil that stays in place on tailstock centers. It's as thick as honey and has a lot of ZDDP. ( Never tried using it as a cutting oil). Mike Taglieri wrote:
