Often times I would find vintage persimmon woods with uneven surface on the face. From golf balls missing the face plate. When I run my fingers through the face , there would be obvious concave spots at both the toe and the heel, mostly toward the toe.
I had passed quite a few of these vintage because not sure if the integrity of the wood structure had been compromised, and not sure if I could make the vintage a playing piece again.
What would you do to refinish the face ? I know the face plate must be removed , however, do you take down more to expose new surface ? Couldn't be building up the face , could it ? How to maintain/measure the roll and bulge angle ? By eye and feel or there is another way ?
I'm always worried of taking off too much to influence the shape and the swing weight, majorly don't want to change the original shape.
