    engraving a VIN# ?

    Thanks for explaining it! Now I remember, I’ve seen the german version of VIN in my Miata’s handbook (VIN hidden in a compartement under a seat) Cheers Ralf

    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...

    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...

    This HSS is not specifically sensitive against overheating. I even silver soldered pieces of it to brass supports, and they showed no significant decrease in hardness. I think this is a main property of High Speed Steel (HSS), it was developed to keep it‘s cutting edge when working steel at very...

    Hi, I buy HSS blanks from https://www.zujeddeloh.de/produkte/drehen/werkzeuge/drehstaehle/hss_--509/drehstahl_rund--_4942.html They are a little above 100 mm (4 inches) long. Tungsten carbide blanks I got from tribo.de. They proposed D2,00h6x330 Hm-Sorte U12 K20-K40 330mm long. I can‘t...

    Vectornator. Free and (meanwile) well documented Vector Graphic app for Mac and iPad. Use 71% spirals for the backbones… The functions in Adobe Illustrator that I would like (e.g. smoothing a vector by stroking it with the pencil) where not included in the iPad version when I tried it last...

    Here‘s the set of sharpening templates I made myself: (left to right) 70°; 90°; 105°; 120°; flat graver, round graver For each graver geometrie there are two templates. The small templates are used to grind the shape onto the blank. I use 2mm round HSS blanks, of which I glue 5 pieces at once...

    Apple Pencil

    Apple Pencil One (with lightning plug), I guess… The version two is rumoured to have no battery but a capacitor… There is another interesting thing about iPads / Apple pencils: do NOT bring them close to Helium gas. It creeps inside and disturbs their clocking devices. My colleague (AP1) and me...

    Question: treading on sensitive ground...graver formulas

    A nuts and bolts approach, using the dual angle fixture as a calculator: Take a piece of square mild steel of 3 or 4 mm square. Clamp it in the Dual angle fixture, such that the corners of the square profile are up and down if the tool rotation is set to zero. Turn the tool rotation angle to...

    Asian pneumatic engraving machines: Your mileage may vary. I bought the asian version of a classic GRS machine before I knew about the engravers’s café. So you may forgive me this purchase. I had a new rotary valve body made from Iglidur G as the old one was leaking like hell, replaced the speed...

    Greetings from Croatia

    Correct and consistent graver sharpening is the key to self learning success, I would say. Especially if you’ve got no teacher to show you the ropes, as it is in my case. I started out with the same simple graver sharpener You showed us. I set the angle with an angle gauge. It works for the...
