Mica,  
 
     My curly redwood Darling # 13612 came with plastic backplates.
What would be the approximate cost for brass replacements?

The regular brass thickness is half that of the plastic. So if we make standard plates, they will sit down lower than the surface of the back of the guitar. If we make the plates out of 1/8 brass, they will cost a ton and weigh a ton.  
 
Look for an email with some pricing options.

Just a suggestion. A spacer ring or small washers of proper thickness under brass plate.

Spacer sounds like a good idea. Should probably attach to the ledge so they don't go rolling out of control every time you go to change the batteries. I'll see if my supplier has something that would be suitable.

1/16 plastic or brass with a few dots of glue underneath.

Why don't you do 1/16, brass and 1/16 plastic or wood glued together?

I'snt it neat what great minds can do when we get together.We just invented what I am going to call a gasket.Heading out to the patent office now.

We've made brass plates with spacer rings - just takes time and $.  
 
I'm also awaiting a sample of a brushed brass looking plastic material for an easy replacement on plastic-routed plates.

That might be the answer while I mull over the real brass.  I do like the light weight.
