  • This episode features the Sri Lankan technique for dressing and prepping a metal polishing lap.
    I want to point out one mistake I spoke in the video: around the 3:00 minute mark we used a 1200 grit topper lap not a 300-400 grit lap to smooth out the metal.
    Finally one thing I would like to add to the content of the video is that if you are rescoring during the polishing of a stone, you don't need to go through all these steps. A quick 30 second scoring and then smoothing out the metal with diamond slurry and a piece of synthetic corundum, then a good alcohol cleaning and a fresh coat of diamond powder is all you need.
    Also, I never intended this video to be an example of the "BEST WAY" to polish a stone, only a complete demonstration of the technique of scoring a lap.

    Thank you for the video. Clearly there is no "right" or "wrong" way, just techniques to add to the tool chest for use when the "standard" ones aren't cutting the mustard (or polishing the mustard). I'm a fan of copper and find it works well as a prepolish lap. Good presentation from folks that are clearly professionals at what they do.

    Yes, glad you pointed that out about using the 1200. I was thinking to myself that it couldn't be 300-400 grit. Anyways I loved your video. I am wondering about your machine. Who makes that machine and what do they sell for there? Could you point me in the direction to acquire one? It seems like it must be much faster than other types of machines as it seems that you could change the indexes faster...am I right? Thanks for your help in advance.

    • @JustinKPrim
      @JustinKPrim  Před 5 lety

      The machine is great. I teach on them and I think they are some of the best machines you can use for speed, accuracy, and cost. You can find them here; sterlinggemland.com They are about $1200 plus shipping and import duties from Sri Lanka. Nice people as well.

    My Batt Lap is scratched. Thinking of doing 800 grit wet sand. Would this harm it ? Thank you.

    • @JustinKPrim
      @JustinKPrim  Před rokem +1

      Is the scratch really causing problems? My bat lab has like three huge gouges in it and I still use it just fine. If you really need to resurface it, you could use a used 1200 grit topper like we do in this video. It’s not something that I do very often, this was the Sri Lankan dude showing me how to do it, but I have done it before and it does work. Check out my other video called “uncovering a buried treasure,” where I take a totally disgusting dirty lap and clean it like that.

    You'd think this guy would hit the doctor's office to get that staple or screw-eye backed out of his finger.
    Obviously that must have hurt when it happened and I'm sure it'll hurt when it's removed. But surely it's got to be better than getting i caught on everything and half yanking his finger off.
    And besides, it just looks goofy !

      Interesting. The sri lankans must know what they're doing if they're the ones who use and make these machines. I'll definitely look into this (and watch your video again). Thanks.

    Scary to imply this is the proper way rather than a technique that some use

    • @JustinKPrim

      D L owens I only meant that this is the proper way to score, not that scoring was the proper way to polish a stone. That choice is of course subjective.
