Hi,
The tool is pretty common in brass musical instrument repair. Ferrees
music here in the US can mail you one. They are on the web somewhere. I
just picked up one at a hardware store that was closing... mine was made in
china so if you have any of the stores there that sell Chinese tools you
might find one.

I have need of an old tool called a 3 cornered scaper. It is at
first sight, similar to a triangular file, with no teeth. Does
anybody know of a place in the UK where one can be purchased? Or
failing that, I was informed that such an implement can be
manufactured from an afformentioned triangular file, with the teeth
ground off it by a grinding wheel, and three fine edges left on it.
Does anyone have any experience of this.

You cam make one from a three-cornered file.
It takes some time and patience.
I have several but the best one is made by grinding one side in a
curve. This curve meets the two other (straight) sides in a point.
This makes a much more versatile tool.

IIRC this is also known as a bearing scraper - at least that's what I
bought from Pascal Hardware about 25 years ago ($1.49)

I just caught up with your post Garry.
A bearing scraper (at least the ones I have seen) have all three sides
gently curved.
My design has two sides as straight as I can get them with the third side
curved (rather sharply) to meet the other two in a sharp point.
This allows the tool to get into an internal shoulder as well.
I don't know how many times I have stabbed myself on the point of this
tool
but it also lends itself for use as a scriber in a pinch.

Regards.
Ken.
