Steve I thought I had the trump card with picometers! Never heard of a zeptometer. Surely that's the smallest unit of measurement, no?

Funny...I'm used to looking at scanning electron microscope images of thin sections at micrometer scale (=10-6m). Picometer is 10-12m and zeptometer 10-21m...makes a micrometer seem massive!

Gil, I've never had any need to use a zepto anything, apparently a zepto is a relatively recent addition.

I'm pretty sure that Wife-O-Meters are the best measurement for splitting hairs.

So it looks like most folks here run something between 0.09" and 0.110" thick.

Does anyone use a different thickness based on the top wood? Would you go thicker or thinner if it were a softer wood like Englemann Spruce or Western Red Cedar vs something stronger like Sitka or Adi?

Or would you use a different type of wood for the bridge plate based on the top wood?

My latest build a somewhat period correct 1937 Martin D-18, My John Arnold supplied tracing of 1937 Herringbone D-28 the bridge plate thickness is .95, I also have a tracing of a 1938 OO-18 and the bridge plate is .75

What wood do you folks usually use for the bridge plate when building steel string guitars? I just read that Martin used maple up until 1968 and changed to a much larger rosewood one that year.

From my experience as a player, maple sides and backs are brighter than rosewood. What do you use and what do you think the effect is on the tone of the guitar?
