John Kelley Posted October 10, 2017 Share Posted October 10, 2017 Hello, I'm just barely getting started down the forge road. Plan on finishing my makeshift anvil tonight. Making a 55 forge (actually a 30 forge..lol) this weekend. I'm trying to do everything with minimal expense. Anyway..my real question today is.. Would water based machine tool coolant/cutting fluid work well as a quench for "cheap" steels like 1075? My company actually makes the stuff and I could get a few gallons of concentrate for about nothing. My thought is it must be slower than water though not as slow as canola (which is my next best cheap quench from what I've read) and it's not going to flare up. The main components of the coolant is water, some water soluble oils, soap, and some sodium nitrite. Any thoughts would be appreciated. Thank you John Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted October 10, 2017 Share Posted October 10, 2017 I'd talk to the folks who "designed" it and get their take on it as a quench medium. They should know how fast it takes heat away from the hot steel as compared to plain water or oil based stuff. Quote Link to comment Share on other sites More sharing options...
John Kelley Posted October 10, 2017 Author Share Posted October 10, 2017 Thanks for the reply Mr. Powers. Your idea certainly has merit. Fact is the man who formulated it has left this world. It is now made by following the old recipe, so the knowledge behind the formula has sadly been lost. Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted October 10, 2017 Share Posted October 10, 2017 So your company is making a product that they don't know the technical details about? Must be hard to sell it by comparing it to other maker's stuff... Quote Link to comment Share on other sites More sharing options...
John Kelley Posted October 10, 2017 Author Share Posted October 10, 2017 yes it is..lol Fact is we have a few companies that swear by it and have been using it for years. Basically, the previous maker died, his kids wanted nothing to do with the very small company and sold it to the company I work at for a reasonable price. It is just a very tiny side to the company. Literally only make about 55 gals of it a year....sometimes less. ...it's almost done as a favor to the buyers of the stuff...lol Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted October 10, 2017 Share Posted October 10, 2017 You may be down to experimenting with it---if it does well as compared to Parks 50, there is a market with blacksmiths and bladesmiths---though again a small one... Quote Link to comment Share on other sites More sharing options...
John Kelley Posted October 10, 2017 Author Share Posted October 10, 2017 You may be correct about experimenting. ....though at my level of ZERO experience I don't even know how to tell if it works good or not. Sure I can see if the metal gets hard by running a file over it, try to break it etc...but that's about it with my limited knowledge...lol Just part of the fun I guess!

ThomasPowers Posted October 10, 2017 Share Posted October 10, 2017 Well if you lived in the USA you could connect with your local ABANA affiliate and try to find some more skilled people to work with in testing it. If you are on Chiron Beta Prime then you are out of luck... Quote Link to comment Share on other sites More sharing options...

Desmond Redmon Posted October 18, 2017 Share Posted October 18, 2017 As a machinist I would recommend no less than a 100% solution of soluble oil, since it is thin to begin with and should not be used on mills due to it's thermal shock to the tool. In years by gone machinists (myself included) used cutting OIL to cool tools and remove chips from mill and lathe operations (broaches etc as well), but in today's terms "coolant" is a mix of water soluble oils and water which are NOT recommended for any tool with intermittent or significant thermal cycling. In a machine shop this means no use on interrupted lathe cuts or any milling tools due to the heat cool cycling since "coolant e.g. 3-5% oil 95-97%" water causes thermal cracking. Coolant has excellent heat dissipation rates which as I understand it would be good for W class steels but risks fracturing most other steels like 1xxx, O, S, A, or L class steels since their desired dissipation far lower than that of water. My personal trials quenching in up to 50% (I ran out of volume in a 5 gallon bucket) was that coolant is good for W steels OK for <1045 and hard on >1045 (test 5160, 1095, d2, s7, a2). Can anyone remind me of the term I am thinking of for the span of time a super heated object is inserted into a quenchant prior to the vaporization phase? I think that is the proper placement for the phase beginning with L? Quote Link to comment Share on other sites More sharing options...

I'm a Pharmacist who works mainly with diabetics, and there is one in the making... an implantable device with live beta cells in a matrix, actually responds to and adjusts according to endogenous insulin and blood glucose levels. I believe the expected lifespan of the implantable device is estimated at 5-7 years? It's been a while since I read about the project, but its in the works!

ThomasPowers Posted October 18, 2017 Share Posted October 18, 2017 "The rule is, jam to-morrow and jam yesterday – but never jam to-day." nunc, nunc, nunc I've also read about the work being done with a two reservoir pump: insulin and glucogen with a CGMS to indicate which one is needed. Either way I turn 60 this year and so unlikely to get either one save on a trial basis. I'm just to sweet for my own good! (listens for the sounds of hundreds of smiths choking...)
