    How To Remove Rust Without Removing Original Scrapings

    Hi guys, As many of you know, I wasn't planning on buying a Bridgeport mill, but then I recently stumbled across a super deal on one. This 2J Bridgeport had been used for years at a San Jose vocational school before it ended up with the private high school that I bought the mill from. The...

    Scraping straight down and datum points

    Hi all, It's been a little while since I've touched some scraping projects. I've been on a roll of machinery upgrades, namely the new to me Wells-Index Super 55. But, that has only lead me back to scraping and checking of machinery. As I've been reading Machine Tool Reconditioning(RTC), I've...

    Camelback Straight Edge Scraping

    I have a 6' camelback that I bought on eBay a while ago with no confidence in its scraped surface -- probably not too far out given that it has been scraped before, but likely not Grade A anymore. My biggest surface plate is 18"x24", so I picked up a 5' granite parallel when it dropped in my lap...

    Scraping a mini lathe?

    Probably a silly question, but I was wondering if anyone has scraped in one of the Chinese mini lathes. I want to learn more about scraping and thought it might be a good project to see how smooth and accurate they could be made.

    Lathe Bed Restoration

    Hello folks, I've found a lot of good information on this forum so I though't I'd pick the brains of the experienced machinists here about restoring the bed of my lathe. I have an Atlas 12 inch lathe, and like many who own one, it's seen better days. I've done a lot of work on the thing (and...

    Scraping Question

    I recently acquired an Atlas 10 with a 54" bed. It has wear along the first foot or so of the ways. In order to scrape the whole bed back together would I require a straightedge that's around 54" long? Would a surface plate that long work if I scraped both sides in simultaneously? Just...
