Used a norton n03 fly press no real pressure on it at some point I'll get a hydraulic press for home but for now the fly press in work will doWow that works incredibly well, if all it is is a round plate and pressing with a hydraulic press!
I had it cut .5mm undersized with the intention of smoothing it out but it came out slightly larger I've smoothed it out by hand with a finger file, I will create a lead in when I get it mounted to my positioner with a die grinder then smooth of with a finger file, I've another 4 planned of different sizes if I get this one to workIs the hole in the plate just plain jetted, no finishing/polishing? It doesn't seem to cause any scoring.
