    This is why I have a 3D printer

    This was as far as I can tell PLA or a close relative. I mean seriously who would think to use PLA for a window security part that is constantly bombarded with UV?

    Making metal cones for antique Scottish sporrans

    This is what I had in mind. A male and a female die could be made using Y wrapping to the A axis on a 4 axis CNC. Assuming annealed cartridge brass ~ 0.8mm thick, the rolling pressure required to emboss 0.5mm deep is approximately 4kN/cm width. (DM if you need to see a lot of math). A...

    Shop Truing up Diamond cup wheels

    Well, after watching that video I took a look at my collection of wobbly wheels. To my horror there were 8 that I had put aside for various reasons. The Quorn grinder doesn't like an out of balance wheel - so these had been tossed in the Tuit drawer. About an hour later I had a perfectly...

    Making metal cones for antique Scottish sporrans

    IMHO likely not cost effective at all. The filament for sintering is very expensive, as is the post-processing. Printing is also slow - about 30 minutes each would be my guess, based on a 2" part. Print success rate ~ 75-85%. If the detail is not as important, the die stamp or roller die...

    Making metal cones for antique Scottish sporrans

    FWIW, this is what my AI buddy said.... Sporran tassel cups were typically produced by combining traditional metalworking methods. Artisans often began with a model—sometimes using the lost-wax (cire perdue) process—to cast the cup in bronze or brass. Once cast, the piece was refined by hand...

    I do not see these images in your post. They do open when clicked on. But many of the thumbnails I have uploaded recently do not show up in the post, nor when clicked on.

    Making metal cones for antique Scottish sporrans

    Welcome aboard! Probably like a "penny press" - you know, the kind that you might find at an arcade, where you feed a penny and wind the handle. The machine is heavily geared down and it flattens a penny between the male & female dies to produce a souvenir. If you are using annealed brass...
