Calling all Panzerholz Aficionados

This marks my first journey into the Analog domain. My question is for all those who know about the engineered wood material, panzerholz. I'm a digital guy, and over in the digital section, no one seems to have discovered the virtues of panzerholz for digital audio. Hence my journey here, where panzerholz plinths abound. I have some panzerholz left over from my audio stand project and I can't quite decide how to use it. Any suggestions?

Dimensions of panzerholz left over (all 40mm thick):
1. 40" x 8.5"
2. 30" x 9.75"

My ideas:
- platform for my floorstanding loudspeakers (two 18"x15")
- platform for subwoofer (21"x18")
- platform for future additional components (29.5" x 20" (matches two of my other audio stands)

I thought about making bases to screw component circuit boards into, but I don't think I want to get into that mess. After all, my audio stand platforms will all be panzerholz, and all of my components are dampened with Dynamat (where applicable).

Anyway. Suggestions welcome.

Thanks,

Aaron
