I was asked for more information. Sorry for being so vague.
My classroom is carpeted. The tables are trapezoid shaped with a metal plate at each corner. Welded to each plate is a leg and two smaller supports forming a triangle.
These tables are very versatile and are moved around constantly by grabbing the tops and pushing and pulling. The squeak comes from the metal plate and wood rubbing together, I believe.
My thought was to turn them upside down and unscrew the plates, insert tiny rubber washers between the plate and the wood and some wood glue in the hole with the screw. I have fourteen of these in my room. I just see this as being incredibly time consuming.
These tables also have a rubberized edging glued around the edges. The kids are constantly pulling it off. I have tried attaching the edging with tape, glue, and small nails. Short of cutting off the kids fingers (lol), I am at a loss at what to do next.
I like the versatility of these tables. I don't want to get rid of them. What would you do?
