Honeycomb Tops
I'm wondering if anyone can give me more information about using a honeycomb pattern when making the top. I've heard of laminates that use a honeycomb structure, but I don't know much more than that.

Do you mean a double top with a Nomex core? Here's a thread by classical guitar builder Andy Culpepper showing how it's used.

yes, that is what i was referring to. I'm wondering if there are any other instances of it.

I'm pretty sure it's used exclusively for double tops/backs

I exchanged emails with Randy Reynolds (now retired), who told me about 5 years ago that he was the "first luthier in North America to introduce nomex double tops 15 years ago" (that makes it 20 years!) upon consultation with the originators of the concept ... Gernot Wagner & Mattias Dammann. This information is also available on his website:
http://www.reynoldsguitars.com/index.shtml Another luthier (who is currently active and also is familiar with nomex double tops) is famed classical builder Dake Traphagen. He builds stellar steel strings as well. https://www.traphagenguitars.com/ There are probably many others but these are the 2 whom I know of and may be able to help, although I am not sure what you need exactly.

I believe Tim McKnight and Paul Woolson also have quite a bit of experience with them.

Interesting thank you for pointing me in the direction of nomex.
I'm looking for more instances of the honey comb pattern being used in guitar tops. I see that Mcpherson has a carbon fiber guitar with a honeycomb pattern for the top. I suspect this is easy for carbon fiber as it is a good structural pattern without the same issues as wood.

The quandary and key is using the correct amount and an isotropic adhesive. Apply too much adhesive and you defeat the goal and use too little and the skins separate and implode. You can not apply adhesive to the entire surface of the skin and make a "successful" double top. By using Nomex as the core, you are in essence applying glue to the EDGE of a piece of paper.
Steel string DT's are NOT the same as classical DT's in terms of skin thicknesses, although construction techniques are similar.
