Some interesting things about their build:
TOURNAMENT AMERICAN model
RAILING
Produced with Papel Coating on MDF
Impact Resistant Varnish
MDF works but is not high quality.
65 U Profile Jack System Adjustable from 12 Separate Areas Used
I’ve asked for photos but not seen this yet. I bet it is superior to 12 wood screws and some shims.
TAPE
Specially manufactured rubber band
What is this?
SLATE
Marmara Marble (4 cm) =1.575 in
My experience with thick slate - 1.75” on a Unik from Joy - is great. They stay level for years with the public playing on them. Is there some down-side for marble?
Optional (2.5 cm) Slate Marble =1.0"
MASTERS AMERICAN
their fanciest
RAILING
Impact Resistant Varnish Coated on Imported Plywood
Probably Baltic birch with an oak veneer.
