    Junair Air Compressor help

    Just checked my Jun-Air, it’s got just the this valve to get the water out, no plug at the bottom of the air tank. From my own bad experience, when I let the water out the first time after buying the compressor: this could be messy, rusty water and oil stain clothes and floor quite...

    Need help with graver sharpening

    When using round stock, I grind a flat along the rod opposite to the business end first. For this I set post dial and tool dial to zero. This flat serves me for orienting the round stock the same way all the time. The angle tables provided for the GRS Apex system are also some help, even more...

    What software

    When using the iPad, I employ Vectornator (this app is free) to import images, draw in the cuts as Bezier curves (aka splines) and scale them to the size I’d like them on the metal. It could also draw spirals for the use as backbones easily. Try a decay of 70%, it fits a Golden spiral.

    Progress on copper laps

    With mine, I wipe them clean with degreaser once they are slow down in cuttings speed or leave scratches in the polished face and heel. In case of the polishing wheel with 0.5um diamond paste it might be steel debris buildup that causes the scratches. One day the brass disc should be charged...

    Progress on copper laps

    Yes, 5cm is almost 2“ (5.08cm). The discs are 2mm thick (0.08“), punched out of sheet, roughly 2 $ per disc. As they are punched out, they are slightly domed upon arrival, it tooks some work to flatten them. This litte machine I made over easter. It works very satisfying for me. I‘ve just grund...

    Progress on copper laps

    Initially I was using diamond paste only for polishing. But after some encouraging reading here and at the faceter‘s guild I bought coarser diamond preparations and shape HSS gravers with 40 micrometer grit. Copper laps for shaping and prepolishing grits, hard brass for final polishing with 0.5...

    Question: turntable

    As I said a month ago, I‘ll replace my high-friction turntable. Did it saturday. It‘s a small potters wheelwith two 6062 ball bearings. It’s got a M10 thread which comes in handy to fix it onto my height-change rail. Cutting curves works much better now.

    3d printing a little workbench organization

    I‘m completely in favor of 3D printing. We used to have a 3D scan and print shop in the Karlsruhe city center, but they relocated and I would have to send files and recieve the printed parts much later by mail. I use CAD software a lot and did designs for complex 3D printed parts already...

    3d printing a little workbench organization

    When you liked the flat wooden graver stand, you might like this as well: It was a foot of some old furniture, could now rotate around it‘s magnetic foot and stores most of my flexible shaft tools. Saw something similiar in a Karlsruhe goldsmith shop, recognised it‘s potential and made one for...

    3d printing a little workbench organization

    Dear John, I believe it is dental laboratory equipment. I bought it about 20 years ago here: https://www.goldschmiedebedarf.de/product_info.php?products_id=11944 Still available, mine had a transparent plastic lid as well, normal length dental burrs do not fit under it, just the „RA“ stile...
