JimPAC,
The entire piece was milled... the center hole and the taped holes were drilled on the mill as well. After milling, I placed the piece on the lathe to chamfer the edges and about 15sec with a sanding block.
I can lathe some of the operation but the main holes still have to be milled becuase it is exactly 0.505. A 0.5" pellet fits inside so dimension of the holes have to be exact.
I can tap after finish so no need to cover the tapped holes. So if I bead blast... will it be able to remove tool marks inside the holes as well? What type of media should I use to remove tool marks?
