Thanks trickflow for making such nice ports .
I'm roughing up/ removing the CNC step over.
I will cartridge roll these the hit the floor and bowls with a rougher burr finish.View attachment 1716380691
Do you have a pic of an unmodified (by you) port for reference? I’d like to see the step over you’re talking about if available (or do you mean all the little the grooves the CNC machining leaves?)

Edit:
I googled stepover and learned a thing:)
