    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...

    Here‘s the pattern I let rotate on top of the workpiece with the turntable to center the microscope.

    Microscope

    I developed the following method for microscope centering on turntables: I used a b/w laser printer for a 2D dot pattern with about 0.3mm spacing on white paper and glued this to a magnetic label for inkjet printers. Place this on your work piece or on the ball vise‘s jaws. Center the vice...

    personalized silver liquor cup

    Very beautiful and precisely done. And you do not use pneumatic assisted tools, it’s all hand push engraving? Nur Handgravur, keine Druckluft Unterstützung? Cheers, Ralf

    What material ist the „ceramic wheel“ made of?

    Hi Archie, I use currently a brass wheel for polishing with 0.5 um diamond paste. It works fine in 95% of the cases. Every now and then, a graver „bites“ into the brass surface. I choose the sense of rotation always so that the wheel moves away from the „keel“ of the graver. I was just curious...

    What material ist the „ceramic wheel“ made of?

    Hi, I want to add a „ceramic“ wheel to my minihone. I use 50 mm wheels. Does anybody know what the original „ceramic wheel“ ist made of? The price suggests some high tec ceramic, like aluminum oxide or zirconium oxide. I could probably order a 50mm wheel made from such material to my...

    Inlaying Dots (small circles)

    If you want better control with rotary tools (burrs), and have to remove only a little material, rotate the burr backwards. I took this tip from a stonesetter‘s post at Ganoksin. It works well for Silver and Gold. I never tried it in steel. The backward rotation prevents the teeth of the burr...

    Does fine silver = easy job?

    I believe your equation „high end tool + soft metal“ lacks the years of practise required to cut the pattern in good and even quality… The pattern is definitely not an easy one. Many say Fine Silver is not easy to engrave. I cut only Argentium which is a good deal harder. I do not want to...

    Question: c-max carbide grade

    I wanted to try out carbide gravers at stainless steel last year without paying a fortune for the blanks. Instead of trying to find out the ingredients of C-Max or Carbalt, I went the other way round and asked german carbide manufacturers which grade they would recommand for “cutting metal with...
