I know by now you have read a lot on removing pins, but here is my way.
1. Put 2 layers of blue tape covering the pin and the scale end to protect it.
2. Use a Needle file and flatten the top of the pin by filing thru the tape.
3. Use a micro Sharpie to put a dot right in the center of the pin to make it easier to see.
4. Use one of these... But much smaller in my drill press. I chucked up this big one just to show you better what it looks like.

I've put a long wide slot in a board that the scales lay in to help hold it steady while drilling. Drill slowly until the bit grabs the collar and takes it off. At that point, the scales should just about fall apart.
The bit I use has a tip that is 1/16". The same size as the pin. If your off-center a little a thin piece of the pin will still be sticking up, but it will be so thin it will flex out of the way.
Good luck! And Practice!
