No clamps, I did not attempt to squeeze anything back together. Super glue dries very fast, usually within a minute or so. If you waited an hour, youd be fine. I soaked in pretty well because its so thin and did not seem to swell the mdf. I did tape up the wall and play surface around the goal, in case I got sloppy.
Side note: Alaskan Thunder (seems like a long time fooser and seen/dealt many tables) does not seem to think goal blow out is an issue any more on the Tornados.
