Don…..you’re a Genius - Love your videos, That said; might I also suggest that the vacuum source would need to be much quieter, or isolated in another room so that the cartridge does not pick up that noise and transfer it to the recording, especially for quiet pieces. I once had a phono cartridge pick up the sound of a low-flying plane and could be heard on the resulting transfer - I know this is only a proof-of-concept video, but definitely, the vacuum source needs to be isolated - again Love your work.
2 minutes is probably not long enough to kill your vacuum cleaner, but this will kill a vacuum cleaner if left on for any long period. It needs a lot of cooling and it uses the air flow to provide that cooling. But once this is sealed up, the motor will work very hard (much harder than usual) and get little active cooling.
To play a broken one you would need a lead screw, with the same tpi as the cylinder, so that the stylus would track right to left by itself, there is only one other alternative and it would create the problem of possibly wearing out the groove walls
The machine does have a feedscrew, which is computer controlled to move the carriage/cartridge/etc... at the correct speed. It can be seen in the other videos I posted of the phonographs...
Very interesting concept Don, well done. Hope to see more at ARSC in May.
What an amazing concept! This could be a big deal for archivists.
The potential for this is awesome

Thanks, Steve. The Shop-Vac isn’t ideal, luckily there are plenty of other options for the vacuum source.
Don : You are a Genius!
Very clever 😎👍
