    Microscope camera question

    Look for the word “trinokular” in the scope’s description… They usually combine light from both objective paths for the third, straight port, where the video camera sits. Cheers Ralf

    3D illusion engraving

    Hi Monk, Thanks a lot! When I find out why my iPad doesn’t let me upload the pictures in origignal size, I’ll post them again, you’ll see the imperfections were the lines getting close together then… I use a stereo microscope, the field of vision was about 1.5 cm. When I set the magnification...

    3D illusion engraving

    This time I cut 35 lines at the 1” square surface. In the places were the lines are compressed, this seems the limit of my printer as well as my cutting abilities. Cheers Ralf

    3D illusion engraving

    Here are the details: germanium alloyed sterling silver sheet 0.5 mm thick, cold rolled down from a 4 mm ignot with annealing after every 50% thickness reduction, this alloy cuts very well and stays bright for a long time annealed while the jump ring was soldered in the corner flattened...

    3D illusion engraving

    Hi Monk, I engrave only the jewelry I make in my studio. I haven‘t given it a thought yet. I did not intend the 3D effect, I was surprised by it. It is suitable for things that move, like earings and pendants… For a start….

    3D illusion engraving

    Hi folks, ready for some abstract engraving? Normally I don‘t dare to post my work, as it‘s jewelry and I‘m not gifted on the (hand drawing) artistic side. But with the help of Procreate‘s Liquify option I created a pattern that surprised myself when it was engraved. If you look at the first...

    Graver or Scope?

    My microscope (Olympus SZ40, X20 oculars, 0.62x Barlow lens) made the huge difference for me, at the time for stone setting, which required only short graver strokes. Quality and control was much better than with the Optivisor. Stone’s size 1.5-3mm, three or four point bright cut settings. I‘ve...

    A working Brother printer transfer method

    Hi T.G.III, I read about your aftermarket toner post before and was pondering buying some non-Brother toner. The sandwich paper was the last attempt before changing the toner. Cheers Ralf

    A working Brother printer transfer method

    Hi Monk, that‘s the problem with recipes from other continents, the brands of stuff we put to an unintended use are hardly comparable… But I know of some european readers in the Café, maybe it helps them. The paper roll in the attached picture maesures 28 cm x 16 m, did cost about 1 Euro and...

    A working Brother printer transfer method

    I’ve finally found a transfer method that works with my Brother laser printer. Brother’s laser toner is notorius for unreliable aceton or Dammar transfers. The advantages of my method are: no printer or toner modification, no expensive transfer paper or plastic sheet, no paper fibers left on the...

    Saltwater Etching Instructions

    When you are patient, you can etch copper with powdered sulfur and olive oil. No, I’m not joking, it works. I got the recipe from a french book. I use it as substitute for liver of sulfur, to blacken silver and copper. If you leave it longer on the surface, it attacks copper. Works best warm, I...

    Trials

    I wipe the sides of the blades with candle wax in the direction of the teeth for lubrication. Sticky stuff like oil, burr saver or pure beeswax did not work so well. Most breaks occure to me on the upward stroke, when some chip of silver jams the blade in the cut and the workpiece lifts up...

    Heel drag issues

    I recently discovered that too short a heel causes problems with heel drag. I agree this sounds paradoxical. The same graver geometry (face/heel/V angle) I have to hold over the workpiece at a lower angle to achieve a constant cutting depth when the heel is very short, and at a steeper angle...

    innovative german workholding system for irregular 3D shapes

    Saw today an innovative workholding system for irregular 3D shapes. I put a coaxial connector in it just to demonstrate the principle. see picture. All the pins are spring loaded, you put your workpiece in and thighten a bit. The pins will conform to the surface. And now, you can lock the pins...

    Gold turning greenish in pickle

    Nitric acid attacks silver and copper, but leaves the gold alone. Hence the german name „Gelbbrenne“ (yellowing pickle). Muriatic acid might actually work, as it attacks Silver, but is soon stopped by an impermeable layer of silver chloride. As there is very little Silver to dissolve, it might...

    Gold turning greenish in pickle

    Hi Aman, this is a perfectly normal behavior for a Gold-Copper-Silver alloy. When soldering or annealing it, only the copper oxidises, your workpiece turns black. The citric acid pickle (as well as the sulfuric acid, sodium bisulfate or the sulfamidic acid pickle) dissolves the copper oxid but...
