Hello Hammergun,
Thanks for the tips!
This is good info. Once I get that wood screw removed, I can follow these directions. One interesting point is that there is no screw under the top lever. I see where a bottom screw threads up into the top tang, at the rear-most edge, but there is no bolt hole or screw under the lever.
Thanks for the information and tips!
The biggest problem is that a previous owner buggered the wood screw, and it is in there TIGHT.
I will try the drill press technique to create constant downward pressure while attempting to unscrew it.
If it is a wood screw and the head continues to disintegrate, I know I can remove it and repair any wood hole issues with a hardwood dowel cut to fit. I was just being cautious until I figured out if it was wood or steel that it was threading/locking into.
I just hope to not need to do that.
I am also sure I need to replace this screw once it is out. I don't want to put it back in and have the same problems next time.
At least it isn't one of the engraved screws from the bottom of the floorplate.
