Hi Arnold, I was going to say I use hot rolled commonly, and if one puts the pieces in some vinegar overnight, it will remove the scale and leave you clean steel to machine, and you don't have to wipe out your high speed cutters, and they will leave a better finish without the scale wearing the edges prematurely. I also have some scrapers, made by taking a piece of rod, drilling and tapping a hole in the end, and screwing a TNMG insert to the end, with a handle put on the other end. This is a good scraper for removing the mill scale by force and it works well in taking bumps and nicks out, and deburring a long milled edge, and can't be beat for scraping surface rust of steel or iron without gouging it up, as the negative rake keeps it from digging in. I even use used inserts on occasion, as they tend to get all their wear in the tips, while most of the work of a scraper like this is on the straight edge between cutting tips. A scraper like this, with dark sulferated cutting oil will take surface rust off a machined surface leaving it smooth and no more than brown stain as long as it's not pitted, and does even better on machined cast iron surfaces. An insert will last me a year or more, with two or three of these laying around by different machines and used anytime it seems fit. It's the hard way to take of hot rolled scale, but it does leave a clean surface. for what it's worth :poke: mad jack |

Hi Arnold, and I thought it was my computer screwing up leaving out all the pictures :poke: the post looks much nicer, and is easier to follow with all the pictures in place, quite a nice job and very useful I would say. A solution of vinegar also removes blacking from heat treatment, or bluing from guns, and the like, for silver soldering. I tend to leave the blackening on from heat treatment just to keep me straight on what's been heat treated, and what's still in it's original state. Now I'm looking forward to what you're going to build out of that lump of metal you scribed with your new height gauge. :beer: I hope you put your initials on the gauge assembly, got to leave something for a future owner to puzzle over. I've just started marking the tools I make, it didn't matter when I was younger, but now that some of my own tools are reaching back into antique range, I look at the marks made by some of their former owners, and wonder what they did with them. Ta ta for now, mad jack |
