Thank you, i knew that clamshells had some pretty weird stuff going on. I hadn't tried digging deep enough into the subject yet to understand very much of the engineering behind them. I appriceate suggestions, it's pretty new to me.
So far i've got the axle between the jaw halves sleeved with 2 sizes of brass tube. I'm not sure how much closing force and weight something like this needs vs overbuilding it and reducing lifting capacity / working reach.
I do know that trying to keep the lines on this attachment balanced without them going slack or the bucket opening really makes just running a poorly built dragline bucket seem downright simple!

I run a Flysky FS-I6. Due to the next post, I'd like to set up a switch setting for Dragline that runs all winches straight, and throw a switch for jareds suggestion of mix the lines for clamshell ops.
This looks like i can set up switching Normal and Sport modes for Crowd and Hoist epa. So i can make 'Noob' and 'Send it' settings.

Not sure if my rig can actually toggle a Mix.
I'd also like to be able to run a servo slower than its nominal transit speed
