[QUOTE="Randy338, post: 148137, member: 7022"] Well guys the EDM that would be used in a Barrel Chamber would be a sinker type NOT a Wire EDM..Wire would be used on like a action ,something with a through side to it of closs to equal size...Any kind of EDM-Wire or Sinker type. Can hold very close tolerances...But with any kind of metal removal there is always a drawback...With EDM there is what is known as a recast layer. This is a layer of material that is metalurgically changed after the process. As for a chamber it should work fine but there is an amount of change in the metal structure. Wire EDM has less recast layer on the metal surface than the sinker type. On the sinker a electrode must be made in the male form to burn a hole in the female form. Your tolerance and finish can be controlled by the amount of flushing,Electrical current and material being used for the electrode to name a few..Should work great for a chamber if process is stable enough...Still like the bored and reamed method ..a step better would be a complete ID Grind operation...But who could afford it?
