[Jukebox-list] OT: The shape of the playing tip of steel needles.

[Dicecco, Michael]

Glad you found some of this helpful. 

Re the brake: many machines used a small piece of round leather as the
friction material. Many shoe repair shops carry this, or you can get it
from one of the suppliers I mentioned. 

I should have mentioned that the speed of the turntable will need to be
adjusted. I use an inexpensive strobe scope disc to set it at 78rpm.
You can contact me off list at michael.dicecco at rbc.com and I'll send you
one. 

Did you know that early Columbia records were recorded at 80rpm?

Let me know if you have any other questions. Enjoy.

Mike

Mike,

Thanks very much for your mail which is impressively full of information
that is valuable to the beginner in these machines. I expect to spend a
lot of time exploring the articles and links in the websites you
suggested.

I'll be looking into the motor unit very soon since, as I said the brake
is not working very well and so the motor runs until the spring is fully
unwound.
I will also dig out some of the older 78s I have in my collection. At
the very least I know I have a few first world war 'patriotic' songs
including 'It's A Long way to Tipperaray' that are well before the
thirties and should be tough enough. It has to be said that some are not
in top condition but we can see how they do. There are also some 12inch
HMVs that are too big for the AMI B.

This will definitely be a chance to explore some of the items I've
collected and never really played after I bought them.

Thanks again for your help.

regards,

Doug
