    If you wanted anodised aluminium, making a split wooden pattern, and casting it would be not a bad option as you would save a lot of material that way ... but you would need a metal lathe that had a big enough swing to clean up the casting and cnc would be best for a consistent finish. If it was a 4 axis cnc mill you could also add another design element such as the sweep of each ring spiralling into the next..

    You can spin ally on a wood lathe and use a spindle gouge too with no problems



    A lot smaller, but no problems doing it on my wood lathe..

    I have never tried it with brass, but if the occasion ever arose then I don't really see why not? If anyone knows any different then I will bow to your experience..

    I had the speed for the ally at about 1000 rpm as it is a small item and held it in my O'Donnel jaws with support from a cone live centre at the other end. Then slowley, slowley. I finished up with a huge pie of ally wool for the size turned!



    Light cuts. If you try too heavy cuts it chatteres like hell! And keep your tools sharp. If you have decient HSS tools they don't blunt too quickly.

    High speed steel tool bits are still used on lathes, mills, drill presses, and shapers for metal cutting of steel, brass, bronze, aluminum, pot metal / zinc, and cast iron.

    I have faced a cast iron face plate with a sharpened broken Phillips screw driver bit using a metal lathe.

    One must use the proper surface speed per minute. See:

    Machine Shop 2 - Lathe Cutting Speeds - RPM Calculations
    So much timber, so little time.

    Blasphemous to the gods of music as it is, i've started to mock up a basic version of the lamp using a few of my less treasured vinyl records, just so that i can see the sizes of everything as well as get an idea for how hard it'd be to to get tools into some of the undercuts

    25 layers used so far and i think there's probably going to be another 25-30 layers of rings and circles to complete the shade

    Never stand up when you can sit down!

    Never sit down when you can lie down!

    Oh I give up?

    Good luck with your new record lamp shade or whatever it is. I don't really connect very well after a 5 hour French pre Christmas lunch Not enough wine? Or should that be the other way around???

    Now THAT"S a good idea. The form has come from the objects used then. You have 60 "less treasured" vinyl records? I don't even have 60 records. If you want any help I'm just here.

    Haha, i was gifted quite a few by my dad, but in this case i can get a lot more bang for my buck by cutting rings out of them so one record can be used for 3 or 4 layers
