C96 Stock repair ?

If it was mine. I might say I am not too heavy into C96 apparatus.

a drill press is not a mill. I personally think the mill is the best machine for this attempt, just an old guy's opinion. The mill is lots more stable left/right sorta speak.

I would ponder the actual line of travel thru the stock of the screw , and try to get that line upright to the cutter. Not sure how to do that other than by careful eye, and then use an indicator to center the top of the screw proper the best I could.

I think I would use a carbide centerdrill to establish the divit for the drill to follow. The carbide and the attributes of a centerdrill(relative stiffness) will help get things started.

Screws are not too hard I do not think, so a HSS drill(135 degree) would be my choice, unless I had carbide drill on hand. Let there be gentle movements.

A little Kroil on the bottom existing screw/steel support would not hurt before using an easyout. I do not know if the screw is threaded on top and on bottom, but a little Kroil helps threaded objects come loose with judicious persuasion.

A bit touchy to set up, but is done everyday really.
