on rib notching

Hello list,
Would anyone care to share their technique for locating and notching rib ends into the inner rim?
My first piano I used two sided tape on the rib ends and set the board in - the tape stuck to the inner rim and I used this to cut the notch.
This was not as accurate as I would have liked.
Some of the other problems were the shape of the rib end - being tapered presented some difficulty with this notching - trying to match the taper was not easy. On the second piano the rib ends are flat.
Also the depth of the notch - should the depth of notch exactly match rib end hight? Be slightly deeper?
How thick or thin should the rib end be? Thinner is better in my mind. Is there a limit on how thin?
Thanks for any insights.
Gene
