There is an introductory article in the current Horological Journal.

… To be followed by a constructional series, commencing January 2013.

It looks an excellent device; as one would expect from Jim Arnfield.

Unfortunately, the price of the specified Tungsten Carbide wheel might come as a shock.

Any thoughts ?

Michael, personally I'd forget it, you can almost buy a trio of Valorbe combination pivot file / burnishers for less than the price of that stone, …….. that would give you left and right hand edges in a choice of narrow or standard blades ………. and one spare

Not sure about current Bergeon kit, but i think they're similar money and do a superb job, all you have to do is dress them well!

Fair comment, John

The difference, of course, being that the classic File/Burnisher is a hand tool … requiring great skill to produce precise [as distinct from shiny] work.

The beauty of Jim Arnfield's device is that it's a "settable" machine

My apologies Michael, with the thread title and no access to the original article to go by, I assumed it was a hand tool rather than a machine,

Hand burnishers aren't that difficult to master really, there is a skill to develop, but just like competent filing, it needs practice,

John,

Absolutely no need for apology!

For info …

Jim's preview article shows the attachment being used on a Boley F1, and also on a Schaublin 70; and he mentions that it should suit the Myford ML7, etc. … so it looks pretty versatile.

If you don't take the HJ, it's definitely worth seeing if your local Library has it.

John – you say "all you have to do is dress them well!"

Could you give is your method for doing this. When I was shown how to use a burnisher (a long time ago) I do not remember any mention of dressing.
