A couple, maybe 3, years ago, I added a coolant system to my old Sheldon so I could do an order of 25 barrels that would not fit in my Acra/Hardinge. Today I decided to see what the coolant was like. The coolant system has not been used since then. The system holds 7 gallons. Enough water had evaporated so the pump would not pump. Added 4 gallons water and let it circulate for a while. No smell, color and clarity were normal, concentration was 9%, so I had added a little too much water.I don't have any experience with Castrol 9974, but have worked with about half a dozen other coolants, all the way from straight pig fat naturals through semi-synthetic to full synthetics. All of them will eventually go rotten if they sit idle with a scum of tramp oil on top. Anaerobic bacteria can flourish in that environment.
Keep tramp oil off the top and make sure the coolant circulates regularly. An aeration or circulation pump is not a waste of time.
That is really amazing! Dealing with rank coolant is an unfortunate part of my work.A couple, maybe 3, years ago, I added a coolant system to my old Sheldon so I could do an order of 25 barrels that would not fit in my Acra/Hardinge.

The lathe has a 3 position switch - on, off, auto. I have a switch in that circut to control the solenoid. It is just one less thing to mess with when chambering. Turn spindle on or off and the coolant goes with it.Just curious Why a normally closed I assume solenoid as opposed to a foot switch etc, ie manual control so to speak. I appreciate your replies

New Acra 1440TVS variable lathe and want to set it up to flush but also want to flood for threading, etc (I think?) 1) With the mentioned ProCon pump kit set up is anyone using Viper's Venom successfully? Bought the ProCon and have plenty of Venom already on hand that would be nice to utilize of course. 2) anyone try running Oil (ie Venom) in the existing onboard flood coolant system in this specific lathe? Someone in the 28 pages (Ha!) mentioned having an Acra. I see the PM pump/system did not work with oil rather water based coolant. makes sense. 3) if the existing pump doesn't work it is my feeble understanding that I can switch out the existing Acra pump with an oil capable pump? 4) I'm for not going the bread pan catch pan route but I can't get my mind around utilizing the lathe chip pan etc and yet having a separate tank for the flushing. Obviously I have no idea how my existing Acra coolant system would work and tie in possibly (and to what extent) to the flush system. I want to flush and flood and can separate entirely but I believe LVLAaron got sick of spilling the pan, as I would, and "tied" in to the lathe chip pan. sorry for all the questions. I am an overhinker. Thanks in advance
so aaron when you went away from the baking pan catch set-up did you also eliminate your remote tank and just go with the lathe tank/sump? are you using the oem flood nozzle system? and if you are, with the oil?
