Refacing from scratch

Anyone out there know how to establish the arc of a facing curve? What's too much or not enough relative to it's length/tip opening? How do you find the proper length? Any idea where you can get info on other same mpce stats?
I got 2 mpces that were worked on, the facings are almost flat and they don't play. I don't have the reference of the old curve to go by, thus the above question.

Any input would be appreciated.

It's a secret, arcane art, like witchcraft or alchemy. All mouthpiece guys learn through trial-and-error or as apprentices, like sorcerers. If somebody has put a flat curve on your mouthpieces that won't play, you're in deep doo-doo. The table will have to be taken down (if possible) to generate material to then cut down to create a new facing. Depending on how bad it is, it may not be possible to fix them.
The Yahoo mouthpiece group might be a good place to start. Lots of info to be found, tools, measurement, facing length etc.
