Sandvik coromant carbide way scraper
I have a couple of Sandvik Coromant way scrapers, they look like this:
http://yabe.chudov.com/Sandvik-Corom...raper-0578.jpg The stuff under the red plastic tip is a big carbide insert. I am trying to decide if I should keep one or sell both. Are they only useful for high end precision way scraping (which is something that I probably will never do)? Or do they have some more mundane uses? i |

Or do they have some more mundane uses? i One mundane use would be to mount the ends securely to a block of wood and keep it on the verandah. It'd do a fine job of cleaning the dog crap from my boots after a walk in the park. |

Or do they have some more mundane uses? i If you you drop something on your machine way or table, this is a good tool to scrape off the raised ding it made. You might find precision scraping is fun. It is one of those mindless concentration tasks similar to meditation, only instead of just staring at your navel, you end up with a beautiful flat surface. If your kids like making stuff, it might even be something they could do on a small scale. |

Apparently if you start playing with that, you'll probably be making a lot of your own scrapers. Doubt I'll do that, to many projects, not enough time. On the other hand, I've rarely seen anybody get as much accomplished as you, so who knows? Besides, remember that first lathe and sweet Clausing mill you sold? Bet you wish you hadn't at least once, would have made good tools for your boys some day. Plus those don't take up much room, just keep them in your personal tools. Pete Keillor |

Pete, thanks a lot for the compliment. I am, actually, happy that I sold my busted Clausing lathe and replaced it with a much better clausing, glad that I sold two mills and got the Interact, also. I will probably keep one of these Sandvik scrapers./ i |

: I will probably keep one of these Sandvik scrapers./ Iggy, I've only met two people who actually knew how to scrape the ways on a machine. Both were OLD, and both made their own tools from HSS blanks. Although I'm sure the carbide will last longer between replacements than a hand-honed edge, these guys both "tuned" their tools about every ten minutes. I think the attention to the "instantaneous" condition of the edge made a big difference in how their work turned out. My question with a carbide scraper would be, "How do you tell when it's not quite keen enough to do the quality job I want?" And then, of course, how fast can I get new inserts? I learned rather quickly that indexable inserts get dull, too! G LLoyd |

I made inserts for an Anderson Bros. handle from pieces of scrap steel brazed to 3/4 x 1.5" x 1/8" carbide blanks that I got on sale for a couple $ each. They work VERY well, and are easy to sharpen on a diamond wheel. I scraped in a Michael Morgan straightedge, then did a set of 3 right angle plates. My Sheldon Lathe was too hard to scrape, had to spot-grind that using the same techniques of spotting but used a die grinder for the removal of material. Jon |

: HSS dulls so quickly even on soft cast iron, that it is a major pain. Carbide stays sharp enough for 15 - 30 minutes. Yeah, that's probably the "old guy" vs. the "new guy" thing. They did pay a LOT of attention to their edges. One guy used a stone, but the other one had a nice diamond lap. Both checked their edges for a blackout on a small surface plate. Lloyd |

I've never attempted a scraping job myself. I probably will in a while, when I completely re-build the old R2E4... if for nothing else, just to check how it is. Lloyd |

Lloyd It's worth trying it, if only to see why you're glad you don't do it for a living. d8-) Back in the '70s, I spent parts of several visits to Moore Special Tool Co. watching their scrapers flattening jig grinder and jig borer tables to +/- 20 millionths, corner-to-corner. Moore guaranteed 50 millionths, but the scrapers had too much pride to stop there. They were interesting people. One was an attractive woman about 25 years of age. I've only dabbled at it. Scraping, that is, not attractive women... d8-) -- Ed Huntress |

Back in the 1960s or so, Univac 9400s had a hydraulically actuated disk drive. When it worked, it worked well. But not for long. I never knew the reason, but these drives were famous for breaking and spraying oil everywhere. Puddles were normal. These drives didn't last long in the market. http://www.iceinspace.com.au/forum/archive/index.php/t-69978.html IBM had (and probably invented) hydraulically actuated disk drives, but I don't recall that they tended to spray oil. http://en.wikipedia.org/wiki/History_of_IBM_magnetic_disk_drives Joe Gwinn |
