Appreciate the introduction to those hinges, I've never encountered them before.

Looks like they're for overlay doors only, though. Wouldn't work for these inset doors.

Blum has a 26mm cup hinge. Not sure if it's small enough to work with your stiles.

Thank you! That just might work. The 26mm are for frameless but I was going to put a block in behind the FF for undermount slides anyway.

The 26mm are probably the closest thing to a solution that won't cost me $300, but those are only 90 degree. Really would like a bit further of an opening with roll-out shelves.

Curious that a customer is demanding 1 3/4" rails and stiles. How many years has she been designing furniture? I suggest you ask her what hinges she wants. I'd also add a clause to your contract about not being responsible for door sagging with the weight of all that glass on that narrow of door parts.

Now you have me worried the glass doors are going to fail. My first glass doors tbh.

The inspiration cabinet is metal.

That's how they did it .

That is not a good cabinet to build in wood IMHO

Also that hinge is not concealed, look close it's a normal barrel type hinge .

Has anyone mentioned Soss?
It has been a few years but, I have used them on 3/4" thick cabinet doors. Soss sells a hinge template that goes with different hinge sizes, which is a must. You also need a plunge router.
The best part is, the hinge offers zero adjustability. ha ha
In the end they worked well and gave the look desired.

Also, how much more would an 1/8" glass panel weigh then say a 3/8" or 1/2" wood panel (or mdf)?

The biggest issue is all that area at the top of the door that can't have a hinge.

And the area of that narrow stile that gets removed for the glass and retainer. Going to make a really narrow M&T.
