I need to make a collapsable, portable table that when set up is beyond stable. I'm a dj who uses real vinyl and I do a lot of scratching and beat juggling. I haven't been able to find an affordable, portable stand for my turntables that doesn't wobble when I'm performing. Has anybody made anything like that? I would be extremely grateful for any advice, or blueprints, or ideas that can help me keep the needles in the grooves of the records! Thanks!
