I've recently purchased a J-30, Breakaway. I think there are others named that. Anyway, I want to remove the table. PO said it doesn't come out. I didn't quiz them any further. I got the table off the legs, but the tubes are not wanting to budge. Question is, how hard can I try to turn or otherwise free them before I either destroy them or cause some other damage. My thought is they are just stuck and perhaps I can find something to unseize them. It's in my way.
