hibjib10987 Posted July 9, 2008 Share Posted July 9, 2008 I went to wal-mart to buy oil to do some oil quenching on a chisel. There were numerous kinds. My question is does the type really matter? I don't know to much about oil. Does viscosity matter? Is there a best kind or is it all the same? Thank you for your help. Quote Link to comment Share on other sites More sharing options...
son_of_bluegrass Posted July 9, 2008 Share Posted July 9, 2008 Steel type matters. Viscosity matters. The size of the chisel matters. Many things matter. The more detail you can provide the better answers you'll get. As for oil, I use vegetable oil heated to around 120 degrees F. ron Quote Link to comment Share on other sites More sharing options...
S.Willis Posted July 9, 2008 Share Posted July 9, 2008 As son of bluegrass says a few more details would help with answers. I also use trans fluid on unknown steels. Quote Link to comment Share on other sites More sharing options...

nc_cooter Posted July 9, 2008 Share Posted July 9, 2008 I second the canola oil. Preheat it to 120f. Quote Link to comment Share on other sites More sharing options...

Rich Hale Posted July 9, 2008 Share Posted July 9, 2008 Now you have to temper it or it will be too hard to work and will likey fail There is a blueprint by Quenchcrack on file with a lot of info about hardening and tempering. Quote Link to comment Share on other sites More sharing options...
tompdw Posted July 9, 2008 Share Posted July 9, 2008 I use used motor oil from my vehicles with some used trans fluid mixed in and it seems to work fine. Quote Link to comment Share on other sites More sharing options...
