I'm learning about working on my bridge to lower the action. I have the string height where I want, but what should the width of the bridge be along the top where the strings rest?

thin...and "half-rounded" towards you.

my bridge is not so thin, in fact is quite thick, what would be the problem with that? Thank you.

The problem with that is, if it is too thick at the top, it will inhibit the vibrations of the strings and adversely affect your tone and volume.

Reedo - that's sort of what I was thinking would be the case. I assume that there is a sweet spot in terms of width. I have worked mine to 7/64" along the very top.

Your 7/64" is less than 3 mm. David Gage, a prominent NYC luthier, recommends no less than 5 mm. When fitting a bridge, he starts at 6-7 mm and adjusts according to sound, with the 5mm limit.

Yes, there are definite maximums and minimums. Too thin, and the Bridge could warp or cracrack. Too thick, And you will lose Tone and volume.
What Don said is Exactly what Gage told me when he worked on my Bridge.

I just checked four bridges made by Arnold Schnitzer. They're all 4mm. That's apparently his standard. He has a large number of major clients, and I'm sure that if 4mm presented a problem, he'd know about it. Nevertheless, 7/64 is less than 3mm.

Thank you, Don, for your fact-finding. Although the top of my bridge is 7/64", it is beveled so that the bottom of the string is resting on a little more surface than the top edge of the bridge, so I may be a little closer to the ballpark. I'll be sure future adjustments take into account the figures you found.
