Sturdy Turntable Stand


I am looking for a very sturdy turntable rack or stand, preferably with a couple shelves below the turntable top shelf. I've seen a couple expensive ones. Any solid ideas that don't cost $3K or more?

DIY: Baltic birch carcass screwed and glued to structural posts, 3 x 3/4" bb layer under solid slate slab, all assembled with elastomeric glue (Chemlink M1). Nearest thing to a concrete pillar.
Oh, brother! It’s the Amish vs the Mennonites. Well, shut my mouth and call me corn pone!
DuPont Corian is great. It’s very stable and inert. Easy to get a variety of eye-pleasing patterns, and machines like wood with a table saw.

sleepstalker, yes, Dorian is very stable. Unlike yourself. Are you happy to see me or is that a 🍌 in your pocket?
