Burnishing pallet fork staff pivots in a Jacot tool

[VWatchie]

While taking my daily walk yesterday, I was thinking about a pallet fork pivot that didn’t seem in great condition and what I could do about it. My next thought—incorrect, as it would turn out—was how unfortunate it was that you couldn't burnish pallet pivots using a Jacot tool. But then I took the thought one step further and realized that a pallet fork is just as symmetrical as a wheel and that it might be possible to use the pallet fork's arm as if it were a wheel spoke.

It felt a bit of a long shot, especially since I had never seen anyone do it or talk about it. But when I got home, I figured it was worth a try—and to my astonishment, it worked perfectly! I was so thrilled that I felt I had to share this, what was for me, a groundbreaking discovery. It’s probably nothing new to many of you, especially not to the professionals, but I hope those of you who, like me, thought it couldn’t be done, now know that it absolutely can

Its great when you discover a new procedure to do something! I usually just chuck it in a collet, as my spindle is very true.

Do you have a tailstock attachment to support it while burnishing like a jacot, or how do you burnish it?

I'm a mad man and burnish from underneath freehand. I get great results this way, using a steel burnisher and diamond paste
