Shawn Borri has an electric cutter for cylinders.

Shawn Borri can probably best answer your questions about cutting a
cylinder. He makes the wax blanks that you would need to cut. But
cutting a 78 is a whole different kettle of fish and pretty much a pipe
dream if your purpose is to be able to play it on an acoustic
phonograph. NO practical means exists for recording onto a disc that has
sufficient durability that it can be played with an acoustic reproducer.
In the 1930s there were disc recorders that cut into aluminum discs that
could then be played back with the relatively crude crystal pickups of
the day. But these recordings were noisy and really only suitable for
speech documentation or amateur use. Vinyl records are still too soft to
be played without significant wear on an acoustic reproducer. But in
order to make a vinyl or shellac 78, you have to go thru ALL the motions
of recording a master in a soft material such as wax or the modern
medium of nitrocellulose "lacquer". But these recordings are WAY too
soft to be played by anything other than a very light tracking force
modern pickup. To make a shellac record, these delicate masters have to
be electroformed into at least a metal stamper (the typical process
includes going thru a metal master and metal mother before making the
stamper) which must then be put into a huge hydraulic press that
compression molds the shellac material into the final record. You can
pay to have vinyl records made this way, but nobody that I know of still
molds shellac records.

Subject: [Phono-L] Cutting records
Any info on best way to cut a cylinder (or to cut a 78 disc) from a
digital file (eg, .wma)?
Any service or individual that does this sort of backwards transfer?
I have one or two digital files of some music pieces (2 minutes each)
that I'd like to have cut for playback onto cylinder and/or onto (78) disc.
Or am I nuts?
Thanks
Kevin
