Club tooth escape wheel

OK, this is to all those "helpers" out there.

Several years ago I obtained the remanents of an "Ithaca, Shelf Cottage #9 (new)". It is all restored now with a new base, finials, dial and other work.

The Welch club tooth escape wheel has never given satisfactory service-having had several mangled teeth. Efforts to hand repair and use the wheel have proven fruitless. I will run for weeks then start refusing to run for more than a little while. It stops in the same general area of the wheel.

Would a rounding up tool reveal the bad teeth? Will I have to find someone to make a new wheel? Use of standard machine tools and micrometer/calipers don't suffice.

I need some ideas on this.

Hi Bob,

As far as I can see, you have no properly formed teeth left on your escape wheel. They are all mangled!! If you can measure the diameter of the wheel, I might have one that I can loan to Bill Curley to copy.

Oh, yes-I was aware of the "adjustments !! " made to the escapewheel while I was restoring. But, like some, I was lulled to sleep because it would run for a long period, then start hanging up on one tooth.
Maybe someone out there has a derelict movement with a satisfactory club tooth wheel.
The measurements are:
34.01mm / 34.06mm
1.3385" / 1.3410" diameter

Richard: Can I please hold you in reserve. A clock with right wheel came up on Ebay and I have a good photo. My Son-In-Law is enhancing it on the computer and we will do the same to my wheel. I'm beginning to feel that dressing will do the job.
