Measuring ring shank with jeweler's scale

Hello all,

what is the “formula” to measure the ring shank using the raytech
ruler?

I thought it goes like this" if the ring size is 5, I should
substract 1 1/2 and start.

is that the correct amount to substract?

thanks
Sonya

If the desired size is 5 you add 3x the thickness of the stock you
are using to fabricate the ring then that is the length you cut the
stock.

That has always worked for me.
