I use “Caboose” ground throws and find that they tend to go all the way over when thrown, making them hard to grab and throw the other way. I use florets wire as the link between the ground throws and the turnouts. Now to stop the ground throws from going all the way over I made a staple from the florets wire just high enough to stop the throw bar level either way it thrown. As I use 1/2" foam board for my layout surface with 1/4" under that the “staples” are 1/4" wide by 3/4" long. With this measurement the plywood stops the staple at just the right height to make the throw of the ground throws stop level. Making it’s just a flip of my finger to operate the ground throws, no more stopping to pickup a ground throw bar.
Now, in my thinking if the ground throws were used prototypal they might have a stop bar just to keep them from being thrown too far if the hand of god should come down and throw one. [angel]
