Locate your local high school physics teacher and get an explanation of the relationship between the contact area of the stylus and the actual pressure in psi. The material (wax, vinyl etc.) will actually liquefy at the contact point from this pressure.

Hello Kenneth,

If you play a blue amberol four minute record with a model C two minute you 
will get sound and you can tell what the song is which surprised me as I did 
not think you would get sound.  You never want to play a four minute with a two 
minute stylus.

With celluloid records the light weight and sapphire will not cause enough 
additional wear for you to ever notice.  Sapphire is softer than diamond and I 
am certain that the H styli will cause more wear than the proper two minute but 
again not enough to be concerned with.

There has been a debate about playing wax two minute records with a Model H for 
many years, one man said he has done this for over 20 years with no wear noted.

It is a fact that playing two minute records with a Model H will cause more 
wear, the contact area of the H is .0035 for Edison.  I would say occasional 
playing with of a wax record with a model H would not be bad, but it depends on 
how you want to treat your records.

For example playing a brown wax with a model C will cause addition wear and 
remove more wax because of the shape of the ball stylus.  Some people do not 
care.

I welcome discussion.

Steve

Bob and Curt,
If I do have an Edison H Stylus put in my Lyric reproducer by Steven Medved, 
would I still be able to play 2 minute record with out damage to them?  The 
Edison 4 minute diamond stylus doesn't work on Edison 2 minute records, does 
it?  I have always used a K reproducer so I can switch between 2 and 4 minute 
cylinders.
This is all a learning experience for me about Columbia reproducers and 
conversion kits and the change in stylus needed.
Thanks to you both for your help, I really appreciate it very much.  Honestly 
even though I might not post always post on Phono-L, I do get a lot out of it 
and everyone that I have met here has been more than helpful.  I must say if it 
was not for Joan and Rob Rolfs in 1993 and how they introduced me to thier new 
Charter Chapter of M.A.P.S. in Wisconsin when I was only 26. Without meeting 
them I would have missed out on one of the greatist joys in my life. Now that I 
have been collecting for 19 years and 45 years old, I still learn new things 
and always will and other than that I feel I have met some of the nicest and 
honest people here that always reach out to me when I am in need of help.
Thanks to you both Bob and Curt, and thanks to everyone else that has made this 
a very enjoyable experience!
Kenneth Keeton

PS:  Sometime I will have to post here the story of how I just happened to walk 
in to collecting phonographs and how it was for me at an early age.  I feel I 
have a very interesting story that goes to show how wonderful our collecting 
community is.

I can attest to the same, Steve does very credible work at a "down to earth"
price.

Ken,If you do find a 2/4 conversion kit, you will also need a 4 minute
stylus in your Lyric reproducer. Finding a 4 min original Columbia
reproducer is another needle in a haystack and not cheap. I sent my original
2 minute Lyric to Steven Medved and he installed an Edison H needle bar and
stylus, along with a copper diaphragm, which works perfectly and solved my
problem. Steven is on the list frequently, so when you need him, just ask...
he does great work.Curt

Curt,
Thanks for all the information.  I printed it out so I can refer back to
it later.  I do that with some posts so that it is easy for me to remember
and cataloged.
Thanks again,
Kenneth

Ken,
If you would like to see what a BE conversion looks like, go to our
webpage: http://www.carolinaphonosociety.com/ After clicking on ENTER, you
will be on the page with a woman and Nipper - at the top of the page, click
on the link "Columbia BF 2-4 minute conversion"
I recently did the same thing you are attempting to do with your BE, to my
BF machine. However, I could not find the actual BF conversion kit and
adapted a BE conversion kit to work. The main difference between the two is
the length of the feedscrew. The BE is approx. 8" long and the BF is approx.
10" long - the adaptation would not have worked in reverse - a BF kit will
not work on a BE.
No one seemed to know much about Columbia 2/4 conversions when I was
researching mine earlier this year, so I have learned quite a bit about
them. First, if you find a kit, it has to include a feedscrew with the
gearing attached and an adapter plate with a locking post for the conversion
to work. Make sure all the parts are there before purchasing one, because
they are a needle in a haystack to find. The pics of my machine with the BE
adapter on it are on the above website.
Although, Columbia made the adapter kits to be used with a number of
machines, they apparently did not make many of them because the cost for the
adapter was almost as much as the original machine and Columbia did not make
4 minute cylinders (other than the Indestructible brand). It was also at the
end of the cylinder age, when most people were starting to opt for disc
records.

David,
I went back and check with the Columbia Phonograph Companion Vol. 1, and
you are very right.  There was more than one attachmemt made to work. on
different machines.
Oops, Thank you for correcting me.  I should have double checked my
facts before talking out of foggy memory and scatchy mental pictues.  Still
I would love to find a BE 2/4 minute attachment.  I wander if the other
attachment for the BK might work on my Columbia Oxford, it was based on the
BK but my Oxford Machinehad has the bedplate and gearing all look to be
identical to the BK.  The Oxford case is plain with trim around bedplate and
base of machine. It is correct to be without decals of any kind other than
the double pinsripe on the Japaned black lacker bedplate.  Information
passed on to me by Tim Fabrizio about the interesting fact that they did not
decal the case at all, just plane oak.  The tone arm conmected to the horn
support is painted glossy black to match the backmount and bedplate, the
elbow connecting to the reproducer and the slide tube are nickeled.  The
slide tube just turns under and connects to the elbow unlike the BKT
  that has a "U" Tube at the end of the slide.  I have a really nice
larger Columbia Black Petals Horn with raised accents aound each petal and
there this is a double yellow rose decal on each of the petals too.  I
really like the way it looks with the black parts of the machine.

I will attach a photo with this posting so you can see the machine.  I
am quite proud of it as I am sure you can tell. But not as proud as my
mahogany Triumph and Home model A long case.
Any ways David,  I would like to say thanks for correcting me, I have
learned many things from the post that have been made here.
Kenneth Keeton

PS:The Picture of my Oxford Cylinder Phonograph is as an Attachment
within this post.

Ken,

I believe the 2/4 minute attachment for a BE, BF, and BG is different
than used on the BK, BO and BQ.  I think I have a complete 2/4 minute
attachment for the later, but I think it is different than what you need.
If you are interested in the attachment for a BK, BO, or BQ, let me know and
I'll locate it and send some pictures.

Regards,
David Boruff

Hello all,

I posted a message several days ago and saw no replys.  I have a
Columbia BE in
fantastic condition and I would really love to find a 2/4 minute
attachment for
it.  It is the same attachment that fits the BK, BF, BG, BO and the BQ.
If
anyone has a complete attachment for sale I would really love to know
and if you
have any leads to where I can find one, it would be most helpful.

Thanks much as alwasy,
Kenneth Keeton
