Another great video.  I have never used the drill press like you did but I learned about it from a fellow car collector that does videos on every step to do a frame off restoration of cars.  Dissimilar metals on motorcycles causes stuck screws.  So I’ve had an impact driver for many years that accepts the gunsmith bits too.  When you hit this with a hammer it rotates to hopefully loosen the screw.

 

  

 Chuck,

 I use the impact driver quite often on anything but guns. The key word in your post is “hopefully”. When you strike it with a hammer, it can be the final step before drilling. I like to stop short of screw damage. T/R

  

I use gunsmith screw bits and I don’t use a sledge hammer.It is important not to let it slip.  So maybe I should have said to tap it?  I think that when trying to turn a stuck screw you are in the same situation.   In either case a reasonable amount of pressure is required.
