Chuck, on reply #11, you show an up-elevator limit screw. I did something similar on DE Stubby. One concern I had on mine, and on yours, as you show in your picture: IF the stick was pulled back real hard, could, maybe, somehow the elevator horn get past the phillips head screw and get hung up on the screw? That would be a bad day. I ended up putting a larger surface, larger diameter on the up-stop screw so the elevator horn could not get past the up-stop.
Just a thought, I can't tell the exact details of your situation.
