Polished prong stone setting system from Rio

Hello again!

I bought this system through Rio. It works great but even though the
item description says 1.5mm to 10mm the largest punch won’t fit an 8
mm stone. I am using on tube settings and love how effective it is.

My question is - is there anyone I can have build one of the punches
that fits an 8 mm size stone? Does anyone know of someone who
already manufactures one?

Any one with a metal lathe, hardened would be nice but not required
for short runs. Off list with all details/dimensions and I can help.
