Depends on what kind of table. If it is a tornado then you have some options.
1st option:
Did you know on a Tornado split top coin-op you can remove all the rods by taking off the handles and bearings. Then take off the legs and store them inside the cabinet. I beleave the rods will fit also. Remove the score keepers and you have a square box. If your moving 2 tables you can wrap both in heavy card board and place on a pallet for shipment.
2nd option:
Find your local distributor and see if you can buy the shipping boxes from a new table. Going rate is about $30 each for split top coin-op boxes. Using these boxes the cost of shipping will be less and the odds you will get your tables accross country with out damage a lot better.
good luck
