    It's easy to wind up with damage on the taper bores, and hard to diagnose without some real care. Taper OD is much easier to inspect, obviously.

    Depending on the rotational speed, I believe you can get ballnuts that are slightly preloaded by ball diameter. That should prevent slewing under light loads.

    One thing to consider: some...

    Light load, low length to diameter ratio for the screw, reasonably centered on the nut(s) so overturning force is minimal - I don't see why not.

    So it sounds like your "bell" is just a flat part? In that case, I'd expect that you could find a sheet of 7075 to do the job. 7050 will likely not be as widely available where you are, but if you...

    If you can get 7050-T7451 (or the European/Asian equivalent) that would be my recommendation. Almost the same strength as 7075, but better retention of properties at elevated temperatures and better...

    I'd try to keep metal types separate if possible, to avoid potential corrosion behavior between Al and other alloys. Ideally this means different bowls and media, but that may not be feasible from a...

    Vibratory tumblers might be faster if the process is tuned right, but if no speed requirements a rotary might be easier to get results from. You can mix media, but it's a bit of a pain to sort media...
