One thing about the mando was that I wound up having to press the frets in with the same block I used to mill the board. Pretty easy with a single radius. Turns out I felt pretty good about pressing frets. I can do a great job with the hammer, but am willing to believe that a press may do an even better job and leave more fret after dressing.

Is there a press system for a compound radius out there?

or I just made up my own flexible caul with UHMWP and a brass strip.

Check out Section 15.6.3 in the white book. Quite straight forward to make your own. The caul in Fig Fig 15.21 can be used in a press as well as a clamp.

Here you go. UHMWP about 8mm x 15mm curved to 10" on bottom, groove cut for fret.
Used for 12 - 18" radius frets.
Originally had brass strip screwed to bottom, but I removed and cut off the ends.

Me too, don't remember a compound radius fret press.

Colin, how does the plastic caul work? Does it flex?

Yes. It's not absolutely perfect, but does a good job if you work it across the frets.
