Pathé Sapphire Ball Stylus - Question

[jamiegramo]

Hi,

I'm in need of a sapphire stylus to play Pathé records. The following stylus is being offered in France at 28 Euros, which seems very reasonable, to play Pathé vertical cut records. But does it look right? It looks pointed rather than ball-shaped. Any comments much appreciated.

Hi Jamie,

It's difficult to be sure without a scale in the image but the two I inherited do look hemispherical on the tip. Looking at images of others on the web, they all seem to be rounder than the one on offer.
Unfortunately, I don't have a suitable lens to get a good image of mine...


PS - on further web browsing (and after measuring mine) the tip diameter should be
1/32 inch ( ~ 0.8 mm). This is correctly reported here:-

but completely wrong on this wikipedia page:-

hope this helps

The diamond disc styli have sharply pointed tips...

Thanks for the replies. All I have to go on is the pictures on the web but using the brass post as a point of scale it looks like the stylus being offered isn't wide or hemispherical enough. Basically too pointed. Perhaps the maker was thinking of Edison diamond discs.

I could write to the seller and ask why the point of his stylus doesn't look like this:

The point does look rather strange but he seems knowledgeable no ? Although the contact with the Pathé groove might be a bit odd as it looks pointy

I have one left of the ones I had made if you want to offer £30 which was what they cost you can have it can't get any more made they were always well liked !

The diamond disc styli are diamonds

Mike,

Does it have a sapphire or glass point? If sapphire I'll definitely take it.

Thanks, Jamie
