By the end of the month I am going to be up to 6 machines with coolant tanks and I am trying to come up with something better than running running a bunch of skimmers. I saw a demo of a coalescer down at the Houstex show a couple of months ago and I am thinking about putting one on wheels and running it from machine to machine on a nightly basis. Is this worth looking at or does anyone have a better suggestion? I am presently running Ashburn semi-synthetic but the Blaser rep is going to do a free fill on the lathe to so I can try it out. The Ashburn does not stink but does turn everything brown and is a little rougher on the paint than I care for.
