French Aerophone

Hi, Pedro,
I discovered it this morning. It comes from an auction sale in Toulouse, 2014-11-21, I spent one hour trying to find sales results, and did not succeed.
You have got a good idea, I'll make the same request in french... Maybe i'll be more lucky.
Rgds,
Pierre.

Bad news. They answered me and its a sad story. Its a lady who is selling the gramophones of her deceased husband. She does not know where that elbow was made.

Yes... Igot the same answer...
Have a lok at this: http://www.primardeco.com/encheres-obje ... 74351.html
I suppose the auction sale did not occur for some reason...

Hi Everybody!
I got it !
It's the end of a long (and expensive) story... My friend, retired, is a traveler, and is sometimes home, and many times away... but he did it.
He used my suggestion to keep a long neck all along the building of the body, and built it in four parts (as stated on my drawing):
- the rotating cylinder neck,
- the sound adjustment cylinder,
- the bottom part for the screw,
- and the body itself.
We had to correct several mistakes on the measures (of course).
Several marks were done when he had to take back the boby to correctly cut the neck which is the attachment of the tone arm.

All the parts are glued with green Loctite.

Then Needs polish to erase the factoring marks...

I have also to find (build ?) a tone arm, because mine is lacking 5 cm long....

... This building has needed more than a full day of work with precision machines, and so could be very expensive; if you wish to do the same way, you had better to find a good friend who knows a good friend who knows a good friend... etc... who can do it !

That's some very nice engineering work , congratulations

C'est magnifique!

It looks perfect. It will need some time to loose some of its shinny to blend with the rest of the pieces.

Congratulations. Enjoy your Aerophone!

You can see inside scraping in the body...
It is because I forgot to leave place for the rotating of the inside part of the tone arm....
So I had to remove metal with hand tool...

I am working on a final scheme of that building, knowing all about, now.

I'll replace the first I posted when ready.

That's a good point, soaking it in washing soda will give the aluminium a dull grey colour

Wondering about why my tone arm is so short, I became aware that the crane is very far from the case...

Able to receive 50 cm Pathé records ? YES !!!

Unfortunately, to reach the correct speed, I had to completely remove the adjusting screw...
And the motor doesn't have enough power to maintain the speed up to the end of the record !

The catalog copy I obtained from Jalal Aro speaks only about "large disc records", and the motor power is only evoked as the number of records that could be played on one rewind...

In my case, a 50 cm record will be just 1 cm too big to be able to play it.

Regarding the power, it might be time to open, clean the springs and oil them again. You can see in this other post http://forum.talkingmachine.info/viewto ... 11&t=21929 that even with a tiny motor you can play fairly big records if everything is perfectly oiled.
