    If your referring to peening the Babbitt, I dont believe Tyrone was talking about that but I may be mistaken. Peening Babbitt is done whenever its poured over a material which doesn't tin, such as...

    Upon seeing your last post, it looks as though it can be saved. Your gear mesh in previous posts is straight horizontal, or so it looked, therefore making it much more forgiving. I would still check...

    It looks to me to have quite a bit of use on it, just very well maintained. You would be surprised how long it takes scraped ways to wear out if they're kept well oiled.
  4. I have seen a grinder run so far out of...

    I have seen a grinder run so far out of maintenance that the labyrinth seals friction welded to each other, .200 deviation from center on the pulley side, and as much as I dreaded having to rebuild...

    Looks to be no more than a few tenths wear to me.

    At .035 wear, your running the risk of gears meshing funny, labyrinth seals rubbing etc. I dont see how re-babbitting is avoidable. On most plain bearing machinery, at rest, the spindle lays dead...

    Not knowing specifically what and where your cleaning I can only throw this out there and let you decide, but easy off oven cleaner removes things that nothing else will in my experience. You have to...

    A small tangent, if I may inquire: there used to be a machine rebuilder roughly in that area of the SD. They seem to have disappeared a few years back; I merely assumed the owner retired or similar,...

    Yes that would be the way I'd go about it. Also, since were talking about scraping methods, with turcite I have found a lovely way to cheat whilst your in the very initial stages, and say you need...

    Was it by chance a kearns? I know the newer machines now use porous graphite under the saddles and it feeds the oil through the graphite giving an even pressure film and while also acting as a...

    I agree with demon on the roughing and finishing. With turcite, since we scrape it a little deeper, it's more important yet. Scraping is just like milling, turning, grinding etc. in that, it's the...

    By how they work I mean ptfe liners like turcite and rulon have high conformability, they're fairly soft, so they dont support hydrodynamic lift at normal machine rapid speeds and when they do its...

    The scraping looks really good in my opinion. From the pictures it looks plenty deep, I shoot for .003-.005 and I know many say .001-.003 is enough but from a tribological standpoint once you...

    It's a copy of a starrett, except starrett uses a little hardened roller instead of the wedge

    What it looks like to me is pinning, like when a file plugs, it's really common on steels and ductile iron. Those two materials cold weld or gall back to the parent material very easily, especially...

    On the plates I've dealt with, it is based off of the bottom of the plate. It really doesn't matter if the plate will get lapped as long as it's on those points all the time. Most likely if it's a...

    Hard to beat oven cleaner, it will remove your paint but also the other stuff. I buy the cheap stuff from the dollar store. O and wear gloves.

    Its interesting to note that while the method they chose to separate the gap looks rather crude, with the drilling and fracturing it from the bed, it's actually quite ingenious from a functionality...

    One red flag that your part is convex across its width, when you go to hinge it on the plate usually it walks sideways across the plate as you sway the one end back and forth, not always, but if it...

    Thanks for the kind words Rich. I only contribute when no one else has. Most of the time, when I get around to reading through the threads, the questions are already answered by the other fellas out...

    If you only need .010 your better off leaving it loose as sauerkraut said. Your spot on otter about denting and scraping tin foil, its hard to bond anything without it needing some attention...

    I've bonded brass shim several times to gibs, it works well, and you can scrape it in once it's bonded, the thing to be careful of is its pretty slick so you need to be sure your prep work is good on...

    Forget about the obvious contamination issue for a minute. Rulon (turcite) is way too soft a material to serve as the longer "master" in any way set. No matter the machine or which axis you are...

    Not ill but very busy, I appreciate the concern.
    This got me thinking of the trak mill that was done about 3 1/2 ish years ago. That mill was hand ground and then lapped, so today at work I lifted...
