Help cuttting hole for underfolder

[Swampcrip]

Im currently working on a childers reciever and have a polish underfolder kit. I really want to keep the stock but im not sure how easy it will be to cut out the needed hole for the pivot pin.

Has anyone done this? If so what method did you use?

I have and do. I used a 2-1/2D CNC
Worked perfect.

Are you talking about converting a fixed-stock receiver for use with an underfolder parts kit?
Childers will do it.
