   Hi Elam,

   Ernie Conover passed on this question to me as I'm more familiar with the plans available on this site.

   I'd like a better description or a photo of the type of table you're looking to build. What exactly do you mean by "three-tier?" And, are you looking to make a coffee table, dining table, or some other variation?

   Looking forward to your reply,

   Hi Matt!

   By a three tier table I mean a  three topped table each with a round top on top of the other. I would like to support each top with a pole in beween the tops. Each top diameter will be smaller the higher they go.    The pole between the tops will be in the center. I need to know the best way to attach the center poles to each table top below and above it. My wife would like this table to go in her retail store to display items at different levels. I may just make a two tier table but that should not matter  as far as how the table tops are attached. The table base I will probably order already made from Rockler. Thanks for you help on this project.

   Hi Elam,

   Thanks for the extra detail. It makes perfect sense now. The first idea that comes to mind is to cut a round tenon on the end of the center pole that extends through a round mortise in the center of the tabletop. The bigger the shoulder of the tenon (this is the flat area that the tabletop will rest on), the more support you'll have. If that doesn't offer sufficient support, you can make a round disk that connects to the center pole using the method described above, that is then screwed to the underside of the tabletop. (now that I think about it, this is probably your best bet)

   The method you choose also depends on the type of material you are going to use to make the round tabletops. If you are using solid wood lumber you will need to take some special care to deal with wood movement. If you use sheetgoods, such as plywood or veneered MDF, then you don't need to factor the extra support into the design.

   In the case of a solid top, check out this article on making a pedestal table. While your base will be different, you can see how the author used a series of cleats to support the underside of the table. It allows for movement and provides good support across the entire radius of the tabletop.
