Thanks for sharing your designs. We’ve got some beginning builders who are just starting to work with 4-bar mechanisms and noticed that you have a few that use a single-wide bar configuration that connects to the center of your claw/collection device, rather than double bars on the sides. I was wondering if there were any issues related to balance, and also how you connected the center bar to the collection device. We use axles and bearing blocks for the double wide lift, but I’m imagining that with C-channel in the center, this could also work, unless you’ve got something more clever that I’m not seeing.
