I saw this so maybe it will help- https://www.youtube.com/watch?v=5eszFbLtKx4
Also the use of some thin felt or similar between the clamp and the record label to reduce wear and scuffing.
Thanks for the feedback. I will try something in between the clamp and label. I have watched the video and I appreciate it. It's hard to know if I'm "over tightening" because you do want the record flat to the resin platter. I just know now when I use the clamp, it leaves a "ring" on all my labels and I'm not happy with that.
