Quoted from vid1900:The next tool you will need is a pair of End Nipper Cutters.
The jaws come together with the perfect trajectory for removing Spiral Nails that are almost flush with the rail surface.
HF didn't have flush End Nipper Cutters and Lowe's/HD only have semi-flush. Where do you get these? (NM, I see the one on eBay from Forceflow. Will order it. I didn't finish reading this topic to the end)
I plan to use a Picture Framing Brad Setter to push the nails back in.
Something like this.
