    scope

    If the scope is that retro (instead of saying old), it might not only need cleaning, but also regreasing. Perhaps you could find a service manual on the web. Cheers Ralf (ditto Olympus SZ 40 from ebay)

    Uneven belly facets with Lindsay template

    From my experience with the Lindsay-style templates I designed and built myself, it might be a slight misorientation of the graver blank holder in either the shaping or the facetting template. The facets are sensitive to a fraction of a degree in graver rotation. Or your different grit bench...

    How nessasary is a class?

    I tried to learn mostly myself. Had a lot of help with stonesetting from a turkish jeweler I met during holidays in Turkey, you could call that a course. We had no common language at this time. Engraving I still try to learn myself, some techniques work (flare cutting e.g.), for some I dearly...

    Question: Cheaper power hones available?

    Hi, I‘m also from Germany, faced with the same problem concerning new GRS tools or machines. I first designed Lindsay style templates which fitted my 2mm HSS blanks and the height of my Degussit (=german sintered ruby) bench stones. They are a little lower than the original half inch. Worked...

    Help with foot throttle

    I assume that you are using a GRS system. It will not work without throttle. The throttle regulates the amplitude of the pulsating air from the control unit to your handpiece by opening the “bleed” path of the rotating valve more or less to to the open air. Leaving it out will mean constant...

    Denatured alcohol to remove shellac destroys the polish

    I’d support the hot glue fraction, easy & cheap to get, detaches when soaked in acetone. I use it to glue flat pieces to the support (wood or MDF). If you stick to shellack (no pun intended), try to soak the piece in Isopropanol, instead of alcohol denat., as you never know what was precisely...

    You've heard of snake guns, well, here's a lizard gun.

    Wow, a double barrel blunderbuss… Beautifully built, no sights required, just point it largely in the direction of the target…

    Graver drift problems

    Happened to me when the graver‘s point (120° carbide) lost an all so tiny chip on one side. Visible only under the microscope. Even the tumb nail test still worked. After sharpening it cut straight again. Cheers Ralf

    Stereo scope comparisons

    Talk about “too expensive”: The Leica A-60 F starts at about 2000$ in the US and about 3000€ in Germany. Additionally, 1€ is worth roughly 1.1 $ at the moment. Leica is a swiss/german company. I wonder how they could sell it in America for less than 2/3 of the european price. Makes me wonder...

    Stereo scope comparisons

    I use an Olympus SZ40 from ebay. I guess I was lucky to get one without damages at optics and mechanics for 250 Euros 10 years ago. Never looked trough one of the famous Leica fusion optic scopes, hence I could not offer a comparison. I work with 10x okulars and a demagnification objektive lens...

    sterling silver jewelry care

    In my experience it’s not the Germanium that makes the cast brittle. I had such problems when I used too small a torch to melt the alloy, thus adjusting the flame with too much oxygen to make it hotter. Nowadays I use a big torch with more BTU (=calories, for us Europeans) but less oxygen in the...

    sterling silver jewelry care

    Juliette, Argentium is a good start. I use it a lot for flare cutting and “manual guilloche”, it cuts well and the cuts stay bright for a long time. Cheers Ralf

    sterling silver jewelry care

    Continuum is, as far as I know, a Silver alloy containing Palladium. It is harder and more tarnish resistant than Argentium, but due to the extremely high Palladium price much more expensive. Cheers Ralf

    Leica A60 eyepiece focus locks

    Very nice idea, which might be useful for other microscope types as well! To avoid the ludicrously postage fees for international shipping, how about putting a .stl file for sale on your video download site? Local 3D print shops could make the focus locks from PA or something similiar strong...

    Inlay

    Prof. Brehpohl was a german master goldsmith and taught apprentice goldsmithes after WW2 for several decades. He wrote the book cited in the article as textbook for the apprentices. It became the standard textbook in both halves of Germany (a rare occasion) and is still used in goldsmith...

    Printable drawings for practice plates

    Hi Dani Girl, did I understand correctly, when I’m going to shade a leaf, I’m not supposed to make the bevelled outline cuts? Cheers Ralf

    argentium and sterling silver

    Argentium looks to my eyes a little bit whiter than normal Sterling silver a couple of days after polishing. When in use, it is a little bit more scratch resistant, so it will keep the shine longer. I do oven-harden it some hours at 300°C before the final polish. Cheers, Ralf

    Looks far too good for a beginner… I’m curious, how and how long did you train already? Cheers Ralf

    Rene Lalique Cirque 1900

    Thanks for the picture! I happen to live a 1 hour drive away from the Lalique museum in Wingen, France. Whe we visited it I was surprised to learn that René Lalique started as goldsmith and jewelry designer before turning to glass design and manufacture. Very impressive exposition they have got...

    Setting up the bench

    Looks good already! Ist there enough space to get your knees under the lower bar in front? In case the setup shows too much springiness (slips out of focus when you lay your hands on the vise or vibrates while cutting), you could put a simple adjustable table leg underneath to give it extra...
