Yes Al, thanks, I have visited your site. Do the compounds come with free wheels, and an add on room for my shop? As I said, not interested in that level of dust without dedicated space. There are other lubricants aside from mineral spirits that can be used while machining, no doubt. I'll just have to investigate those. I appreciate the well-meaning guidance, and it's not that I doubt the efficacy of the compounds & wheels, it's simply a matter of retooling combined with no dedicated space for this work. Does that compute? William R.
