I built a vacuum table for my CNCRP 4896 pro and I do a far amount of routing onto rough cut lumber so I wanted some t-slot track around my vacuum zones but now I'm realizing that with the tracking around the outside edge, it's hard to clamp down anything because there isn't any material for the back side of the clamp to push against for leverage. I've got a bunch of the Rockler clamps but I'm wondering if there is any other styles I can buy or any I can build.
