Glass Cutter Point?

[Martin King 2Participant @martinking2]

Hi All,

I have a very nice antique diamond Point glass cutter that sadly is missing its diamond.

Does anyone know how this might be replaced as I have several other scrap ones that could donate a diamond?

Looks a bit like solder?

I think that you can use a low melting point alloy called "Cerro Matrix" which expands when it solidifies. That's what my FiL, who was a grinding expert, used for wheel dressers.

So perhaps gently melting the tip where the diamond was, the dropping in the replacement might work?

Also probably the way to remove the point that will be used from the old cutter?

Cheers, Martin

Very likely, Martin

Noting also that “Cerro Matrix” is probably in the same family as CerroBend … but may well be a slightly different [tougher?] formulation of alloy.

You could use one of these ?

I made one from a piece of silver steel which I drilled the end deeper than the diamond but a loose fit. I dropped the diamond in with some flux and with it held down with a titanium pin I silver soldered over the diamond with a low temperature silver solder. After it had cooled I ground back the end with a champher till the tip was sticking out. The body of the diamond which was still held by the solder was holding the diamond in situ. Hope this helps.
