Thanks Bob, Jim and Hubby for helping out. After wiggling and spraying compressed air, to no avail, I decided to unscrewed the brackets from the floor and table to actually see what was going on. Not so stupid a question, Hubby. What I found was that there is a plastic sleeve that covers the ends of the metal leg which prevented the compressed air from working. It is also probably there to prevent rusting. (A nice sign of Carver integrity) Plus, the part of the bracket that holds the leg is tapered. So the further you press down on the table top the tighter it gets. You're right Bob, this is the 3257 I just got. So after years of that dinette not being converted (according to the seller), you could wiggle until you were dancing the Twist trying to get it off and wouldn't nothin' be movin' but your own rear end. So what I did after I lubed everything was put a piece of wood inside the recessed bracket between the end of the leg and the table so that the bracket can only go so far. No more dancing. Thanks guys.
