    pretty awesome condition for a shoe buckle.  nice save!

     

    The key is in cleaning it correctly. The original surface is hair thin and totally corroded. You see where it has cone off in a few places. Underneath it fluffy green corrosion, and under that pitted metal with brown corrosion. To preserve the original surface, I dried the buckle slowly, then used a soft brush to get the loose dirt off, then applied a penetrating, hardening oil (Odie's Oil) to stabilize the surface. I used a soft brush to work it in, and a soft, lintfree cloth to remove the excess (and extra dirt). Then  I put it away for a week or so to give the oil time to cure. Now it's safe to handle, and the surface is preserved. You can even see tool marks where the maker cleaned up the casting. 

    if I had rinsed it in water, all this would have been lost.

    I really like the pocket watch case.

    It's a bit of an oddity. The two extra ports at the top indicate that the movement had extra features, such as an alarm, that would have made it quite an expensive movement. The case is disproportionally cheap - super thin gold plating, etc. I've since learned that expensive movements were sometimes put into "starter cases" by the manufacturer, and were intended to be upgraded eventually. As there was no trace of a movement in this case, I would like to believe that the movement, like a hermit crab, found a better home, and that this case was discarded.

  3. Version 1.1 is out. I installed it this morning but haven't had a chance to try it yet. The change log reads: 

    ""V1.1 - Bugs fixed: 1.Remote rebooting issue; 2.WS6 freezing; - Other improvements: 1.The FETID setting is ON by default. 2.Silencer correction has been applied to P1, P2, P4, P5 and P6 to minimize false iron detection."

    Two friends of mine installed it as well and are reporting mixed results. It's odd that they didn't fix iron falsing in Sens FT as well.

    I was very happy with the new audio and then this silencer f...up happened.

    What's going on with silencer? I'm out of the loop, and searching the forums didn't yield any results for me. Can someone fill me in, please?

    I was a tech director for a school system for 20 years, built networks all over the northeast, and worked in IT in general for over 40 years, starting with IBM system 360 mainframes in the 80s.

    If I can get to a site it's up. I seriously doubt they missed the step of having enough server space after a year of development. Just so ya know 🙂 I was on it the whole time, and refreshed. 

    I'm not here to measure dicks, but you should know that you're not the only one here who works in IT. There can be many reasons why a site is down for some users and not for others, but with a circumstance like this it's most likely because they didn't anticipate the number of simultaneous connections they'd have to handle. I assume they are on serverless infrastructure, since they were able to fix it so quickly. Nonetheless, it is an oversight on their part.

  6. Here's a puzzling find from eastern Massachusetts. I've pulled over 100 spoons so far and know a run-of-the-mill plated spoon when I see it. This is different. Between the fig-shaped bowl, the symbol at the inside top (I don't think it's a hallmark), and the notch where the handle detached, this looks pretty old to me. The surface isn't plated. Much more like a wash, or even like tombac. Underneath the silvery layer (which only has a microscopic thickness) is a thick, crumbly layer of powdery green corrosion.
    I am cautiously optimistic that this is indeed an ancient spoon, as I have found 18th century artifacts nearby. My city was founded in 1642, so it's not impossible. But I've learned to control my wishful thinking and am seeking an expert opinion. Any ideas? If not, do you know of a spoon expert?

  7. Rough sanding bit on the dremel, then increasing grits of sandpaper, finally 0000 steel wool. Could probably take it further with a buffing wheel and some rubbing compound. 
    It's really not cleaning, more like resurfacing. The buckle was never this shiny when it was new. I'm also not certain I'll repeat the experiment. I polished another buckle I found a couple of days ago. This one was bronze and came out looking rather tacky.

  8. On old copper I prefer a mechanical approach. I let them dry slowly to prevent the top layers from separating, and the I prep them the same way I prep fossils: with tiny tungsten needles and scrapers, under a microscope. It's very laborious, but I don't find that much old copper and I like doing it. The results speak gor themselves, I think.

  9. On the subject of copper cleaning, I'd like to offer my method:

    This one came from a farmyard in eastern Massachusetts and was completely crusted over. It had good details though. They are preserved entirely in verdigris (the green corrosion that forms on bronze and copper). I scraped the encrustation only from the high areas and left the dirt in the fields. To do this, I used a stereo microscope and tiny scrapers (think dental tools) that I use for prepping fossils. Lastly I polished the high areas a little with a fiberglass brush, and applied a little penetrating oil-based finish.

    Total time spent so far is about four hours, and I haven't done the reverse yet

  10. At this point I am about 20 hours in on the 11 x 13 coil. Here are some first impressions:

    Pros:

    * Coverage is enormous compared to the 9" coil. It doesn't detect just under the coil, there seems to be a significant halo around it as well. It gets my shovel every swing unless I drag it behind me. I found two silvers that rang from outside the area covered by the coil (and, to be fair, many beer cans)

    * Whatever problems existed with drooping appear to have been addressed, or are yet to appear. No noticeable drooping. 

    * There seems to be a significant depth advantage over the 9" coil. I haven't verified this yet on an actual deep target, but air tests seem to indicate it. 

    * Doesn't seem to be a lot more affected by EMI than the 9" coil. 
     

    Cons (none unexpected): 

    * Compared to the 9", it weighs a ton. Swinging it for a couple of hours is a workout.

    * it's not great in dense undergrowth. 
     

    Overall impression: I love it and think it's definitely worth it if you have the 9" coil.

  11. Minelab puts out unbaked software...everybody complains. 
    XP takes their time to do it right...everybody complains. 

    As a software engineer, I'd rather they get it right than rush it to please the squeaky wheels. 

    It gets here when it gets here.
