    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...

    iPad or ?

    Hi Roger, You’re right about the beauty of the Alsace, we live were other people come to for their holidays. I choose the location carefully after living 5 years in Grenoble, in the french Alps. I‘ve not regretted it after 20 years… The iPad is not yet up for replacement, I‘m not using all...

    Handpieces on Graver Helper (newbie here)

    Well, as you have the machine already, you might as well try to get it working. I use the same machine, bought from ebay many years ago, before I knew about the engraver‘s café. You might take a lead from the GraverMax manual (https://grs.com/wp-content/uploads/2019/08/004-041_MaxMate.pdf) for...

    iPad or ?

    I second the 256GB memory choice (iPad 12.9 3rd generation, bought it 2019, still only half full). I bought also a dual port USB-C + USB-3 Flash memory stick for easy file transfer to Windows systems (printer…) and as external memory. For drawing you could also use Vectornator (free), I use it...

    A60 Adjustments

    Paul, did you start using the A60 very recently? As far as I heard (I use Olympus, not Leica) the fusion optics might need some time to get used to, as the two pictures of different size and sharpness are overlaid in your brain’s image processing departement and reconstructed into the large...

    Greetings from Croatia

    I can see where the confusion about the index screw comes from. My brass graver holders are completely drilled trough, hence they have two holes, one at the top and one at the bottom. The set screws have to be in the top, as the flat surface on the graver that serves as index is at the top of...

    Greetings from Croatia

    Correction: If you put a 2mm blank in a 2.3mm hole with the indexing screw on the top, it will sit no longer in the designated center of the template, but about 0.15mm too low. It does not change much for the shape of the graver, but it will alter the heel angle. Too what extent I could not tell...

    Adjustable height chair

    I use one with a large flat seat slightly inclined towards the front. Actually, it was my office chair until the armrests broke. They held the back part as well, so just the seating pad was left, and I use it now turned back to front. This promotes also an upright posture. I replaced the gas...

    Simichrome Polish for finish on ceramic disk

    Yes, I can name it, but as most of you are located outside Europe, it will be hard to come by… It is called MENZERNA-POLIERCREME "Rosa", I’ll attach a picture as well. The name on the package is different, but suppliers often use pictures supplied by the manufacturer. As I already said, the...

    Simichrome Polish for finish on ceramic disk

    I used a german metal polishing compound sucessfully to polish the heels of HSS gravers on a flat ruby stone. The cream ist normally used for aluminum, brass, copper, chrome and noble metals by hand with a rag. The manufacturer makes no comment on the composition. Traditionally such creams are...

    Greetings from Croatia

    As I dug out my sharpening templates for this thread, it remined me of a method I devised (and somebody else might have devised as well) to hone a defined radiused heel onto flat gravers. I do the same today with two adjustable stoppers on the post of the dual angle fixture, the top one set...

    just another picture, to make the flat surface alonge the graver more clear… it serves as index for the sharpening templates

    Greetings from Croatia

    One or two of the 2.35 mm QC holders could not clamp my 2mm gravers with the flat surface ground on without „beer can sleeve“. Also, their set srews were rather soft and developed deformed tips when they had to clamp HSS gravers. Both problems are solved, thanks to the beer can… The main...
