in the past, when I've wanted to cut an interior groove, I've made a tool
from an allen wrench - it's good steel and will take a great edge

That looks like a simple tool to make with a file and a vise.

You might be able to find a large screw driver that can be ground down
and then defined just right. I'm thinking of the 18" long thick ones.
Provided handle and shaft.

You can make a paper overlay for easy testing while filing / grinding.

Thanks Duncan

I went to the web site and looked at the sketch of the tool and believe I
can make this. Being in the US I would probably not be able to easily get
the special made tool from Stiles and Bates. If you have any other
suggestions on a source of the scraper for this application I would
appreciate it, especially if I have trouble making the tool.

There are now a couple of places selling scrapers to make the groove
but
it's pretty easy to make your own, and that's what I did.
If you go to the Stiles and Bates website and look at their Crushgrind
page you'll see one, along with dimensions (although you can just work
from the actual mechanism).

Hope that helps. If you need more info just ask
