Re: Drill Rod 1.25 inch Re: [multimachine] Building a lathe/IMPT
- From that article, "Low-carbon steels typically do not require normalizing." I believe CRS is low carbon steel.I think that normalizing the ways would only introduce a potential for mistakes such as uneven heating and uneven cooling. There is no point in risking handling something that has to be accurate while it is in such a soft state. The article discusses the use of vacuum furnaces. This implies that correctly done normalizing for acceptable results requires something more sophisticated than a pile of charcoal and a mud pit.CRS should serve fine for ways, especially if it is not machined unevenly. Why risk ruining the only two straight pieces of steel in the village when a 0.001 stress in the ways is the least of your worries?I have been thinking of doing some experiments on this, I have to order a small surface plate.Gordon

Dave not to be contentious but performing either is done more or less the same way. Maybe the difference ultimately lies in how much heat, how fast?
A guy once told me to put crs in a crock pot for, iirC, an hour or more. Maybe he was joking. But in any event is.there a way to carefully normalize crs w/o altering the metal (except of course to take warp out of it)?

- Thanks Bill
I think that is the best place to start.
