Steve, outstanding wood working prowess.
The Festool Domino joiner shows you're serious about this & the cabinet proves it.
I'm looking at a Lamello Classic X which is 1/2 the price of the Festool
For whatever reason I love the curved cabinet design and understand the investment in tools, work, patience & time involved.
From the pics it looks like you're using epoxy instead of wood glue.
Certainly a positive solution but far more involved.
Does it have a longer open time?
