Hello everyone, my first post here. I'm designing a height adjustable table for a weld chamber, but the table has 2 independently height adjustable sides. when the tables are not at equal height I want a divider to automatically pop up between them so that material can't fall from the higher table onto the lower table, damaging the parts or falling on the operator on the other side. When the tables are equal in height, the back stop must come down and lie flush with both tables. as soon as they're more than say one inch different, the back stop must come up extending about an inch above the edge of the higher table. I feel like that is a poor explanation, how do i upload an image? I don't know how to get my jpg online so i can use the URL like it wants..
