I have started a plinth build. I’m using composite deck wood from Lowes. The material is very dense with no resonance that is audible when plunked. I ripped 18 pieces 1 x 1.5 x 18. After trial bonding with different glues I found ‘No Nails’ to have the deaf grip I desired. The 18 pieces will be assembled butcher block style. The top will be covered with black Formica and the side’s natural oak.
The finished product should be heavy, strong, dense and most importantly no audible ring (plunking your knuckles on this material is like raping the side of a tightly bonded bag of sand). The choice of feet will be an important key to success with this project.
Just a little more food for thought Jdawg
