    Got any links? I know of the Mini-Sonic (not that I can find all that much definitive data about it), but that's well below ultrasound levels (58ish Hz).

    I haven't been able to find anything online about the process, nor any similar.

    VIN are often stamped into chassis on Land Rovers, for example. ~3mm thick (or so we hope) mild steel - the plastic deformation of the metal is in the immediate area of the stamp, the depth of...

    I confess I rarely read all of the spammers posts - there's a pattern they follow and thereafter I only need one confirmation.

    Nobody mentioned video. Nobody mentioned tinned meat either, which I expect you'll grace us with in due course.
    (My mistake - found it. No, trying to hide links in plain sight doesn't work either).

    Defacing coinage in the UK hasn't been an offence for some years. What is still an offence is "breaking up" coinage (after a specific date from memory, need to check). I've not found a clear...

    I'd suggest that rubber clasps with chain rasping in them probably aren't destined for longevity.

    I've not tried them - is there any possibility you could insert an O ring in the clasp?
    Or alternatively give in and buy another one - the time cost of sorting it is probably higher than the unit...

    Thought that was probably the case, but I was waiting to see. The fact that the IP address and the claimed location didn't remotely tally didn't help.

    As for the kiln - yes, it's a bargain and...

    925 is not pure silver? Pure silver might not have reacted, but an alloy will. Chlorine is incredibly aggressive on metals, which is why I'd never advocate swimming in either salt or chlorinated...

    Good grief. If you order 2kg of copper, that's exactly what you ordered! What's next, will a quarter pounder burger include the weight of the bun, box and serviette???

    That's lovely. I'd agree on the matte finish (especially given the dings it's likely to receive in use); the only thing I'd suggest on layout is that I'd have framed it with a border just to break...

    One tip - to avoid graver tips - *ALWAYS* keep your fingers below the level of the workpiece. That way, when the graver slips it'll go off into air and not bury itself in your fingers.

    I've got to ask - where did you find 0.15mm drill bits? Even making them from needles I haven't gone that fine.

    Even though it's "only" .5-.7mm thick, that's still more than 3 diameters of the drill bit, so you're into deep hole drilling. I don't think I've any drill bits smaller than 0.3mm and they're quite...

    While the difference between sizes is not completely linear - http://www.ringsizes.co/ - the gap between K & L does look excessive. I'd guess that L upwards has been offset by 1 size.
