Re: Coolant/Oil for Chamber flush

Nat,
That is a lot of 308's. I'm thinking you chamber more barrels a year than some of the smaller barrel makers make.

Love your MARS.

Shawn

Re: Coolant/Oil for Chamber flush

Great! Some replies going. Thought I might have to look over on the hide and get whipped a bit for such a question . I agree secrets should be held close but once your in the grave they go with you. "Us" young guys need to learn from the been there done that fellas.

I emailed Greg at GTR and he recommended Re-Li-On for my limited use and long time in between reamings. I also spoke with a rep at Rustlick or whatever the parent company is and he pointed my towards Oakflo products for my needs. Said to stay clear of water soluble all together. I then spoke to a nice lady/rep from Oakflo today and they are gonna get back to me with a recommendation sometime soon and perhaps a sample she said. That would be nice for I only need so much coolant sitting around that will never get used. I have a few allready!!!

So I have been beating the streets so to speak. I want a thin product, high EP, low viscosity is what the nice gent at rustlick advised me to find. "Gun drilling" oil is what he advised. I'll admit I am not all to hip with all these oils/products/terms out there. Back at CST we used what I imagine was a generic cutting oil and applied it by brush. Very slow and I know there is a better way for me even with my low volume.

Thanks for the replies. I'll get it figured out soon enough I reckon.

Keep em coming if you have any thoughts.

interestingly that the guy said to stay away from water soluble cutting fluids. They're kinda the standard in the industry right now, and have been for thirty years. Petroleum based fluid are now only used in gear cutting and certain specialized grinding ops (thread grinding mainly). Still a lot of folks are using spray mist systems for basic surface turning on engine lathes and light milling ops. Mostly used to keep the inserts cool.

When they first started using water based stuff there was a problem with acidity, but that's been gone for over twenty five years. Rusty is right about bacteria forming in them, and we did the samething he did with a gallon of bleach per hundred gallons. I recommend adding bleach to whatever you use as there is a fungus problem with just about every coolant out there these days, and bleach is the cheap fix.

Whatkind of a coolant system are you using? With an open end deal like a gun barrel, a Jet Pulse is the hot setup if you can find one reasonable. It will literally blow the chips out of the cutting area like nothing I've ever seen, but it dosn't work well with super thin coolants like mineral seal.

Re: Coolant/Oil for Chamber flush

I tried the water soluble oils and it started brown staining (rusting) the ways on my new machine in the first couple days. Never again.

I'm now using straight Rigid Extreme Peformance Oil. It's made for thread cutting on stainless. Works great. Doesn't stink or eat my machine. It acts like about a 10 wt oil. My threads look and feel like chrome.

Re: Coolant/Oil for Chamber flush

Hired Gun, Are you also flushing with it or just applying it directly when threading/chambering?


Trickymissfit, I built a DIY setup. Not sure what sort of pressure I am getting for I haven't found my first fluid to run through it to even guess a PSI. I plan on fixing that real soon however to know just what pressures I am running for it seems that verifying a certain pressure and maintaining its setting for consistency, may be a better way to go rather than simply using a ball value to guess my way through fluid flow. Greg also advised me of that.

The Rustlick guy said with intermittent use the water soluble will be troublesome as did Greg at GTR. I don't beleive either were telling me that they were not great products, but just not for me at this time.

I'm a small shop. Once I get all the rifle orders I can handle for a year I'm done. Right now its around 15 per year with my other obligations taking away from expanding operations. When I told all these various folks that number, thats when the "stay away from water soluble" advise came forth. Maybe a chamber flush method isn't for me at this time, but it sure seems like the way to go.

Maybe the gal at Oakflo has just the product for me. If not I'll try something else and perhaps even a water soluble with the bleach trick.

Re: Coolant/Oil for Chamber flush

I flood with the same coolant I mist with. Kool Mist 77. It isn't the best stuff in the world for flooding because it needs to be changed often. But the stuff that doesnt need to be changed so often starts stinking so bad that it gets changed even more often. It yields a fantastic surface but does require a very high equipment maintenance schedule to prevent rusting. - surface is what it is all about not tool life or just walking away from a machine and being able to let it set!. For interupted cutting and threading I use Beeswax

Re: Coolant/Oil for Chamber flush

I am flushing with it. I use it for all threading and general cutting. It seems to work good for everything and the beauty of it is it seems to be good forever. I will probably change it out once a year whether it needs it or not.
