Subject: Re: [Phono-L] Edison Brass Mandrels... some idle thoughts...
Hello Steve
I am new to the site and wondered if you could help. I am
interested
in learning about the Edison phonographs circa 1900 to 1910. Are there
any
good books written on the subject.
The Sound Box. Do you know who publishes this magazine and any phone
number
to call so that I can subscribe?
Thank you.

>> Greetings Harvey:
>>
>> The solid brass mandrels were on the early M and E electric machines.
>> They
>> were press fit onto the steel mandrel shaft. Even in those days solid
>> brass
>> of that diameter was expensive so few are found to be solid after
>> 1896.
>> As
>> the M topworks was adapted for the Springmotor machines the brass
>> mandrel
>> became a hollow cylinder with brass ends pressed in. It was a thick
>> wall
>> brass which still carried some weight. The smaller diameter end was
>> indented
>> to allow for the needle bearing guard on the endgate. In 1901 the
>> nickel
>> plated thin walled drawn brass mandrel allowed for a drastic reduction
>> in
>> brass
>> costs and reduced the number of machining operations. The indented
>> end
>> continued for the M and E but the new Triumph line did not require it.
>> For the
>> rest of the Triumph production the drawn brass mandrel continued to

>>
>> The Home phonograph had the thick walled hollow brass mandrel with end
>> pieces almost from the earliest machines. Only the very lowest serial
>> numbers
>> are occasionally found with a solid mandrel and the indented end. The
>> Home
>> had that thick walled brass mandrel for a long time but wall thickness
>> was
>> reduced as nickel plating was added. The drawn thin brass mandrel was
>> introduced before the 1901 new style cabinet change. The length of the
>> mandrel
>> shaft remained the same until the Model B was introduced.
>>
>> SADLY, there are sellers who swap out the brass mandrel for a later
>> thin
>> walled nickeled mandrel. They then charge more for the brass mandrel
>> than
>> they paid for the whole phonograph. So, you can find a Home with a
>> serial

>> And

>> mandrel
>> for a higher price than the mutt machine. Grrrrr ! ! !
