Hi Y'all,
Anybody actually drilled out the 6-48 scope mount action holes in a PTA to re thread to 8-40?
How hard is the stainless steel?
I've done this on other actions by setting the job up in my mill and using it as a jigbore to drill out the holes then put the tap in a mill collet chuck and hand feed the tap in to and fro small increments with lubrication to prevent breaking the tap.
A lot depends on how hard these actions are
Experienced comments appreciated
Thanks
Peter :D
