Hey all I just recently built a new ebb and flow system. This is actually my third design and I wanted to share the process in case anybody else wanted to make their own table and save some money!
Instead of spending between 300-500 plus shipping on a commercial table, I will should you how to make a stronger table that can be taken apart and put back together for under $200

These are all of the tools you will need: Hacksaw Saw Drill 5/16th bit 3/4 inch bit 1.5 inch bit 2 wrenches
I will break up the parts list according to the source. First, my extruded aluminum framing from 8020.net. I use their ebay store and search by parts number which I have listed.
http://stores.ebay.com/8020-Inc-Garage-Sale
8 ht series connector 4600 $18.80 2 ht series end caps (2 per order) 9755 $3.36 6 Ht series tubes 4 feet 9701 $74.58 8 5/16 18 screws 3111 $2.16
Next is Home Depot. The Walmart of growing pot.
8 5/16 18 2" bolts $3 2 1" x 8" x 8' pine boards $15 1 4' x 8' plywood $10 1 6 gauge steel bar 4' $12 Spray glue $10
Finally, the key to the whole table. 45 millimeter epdm pond liner. This stuff has a 20 year warranty and personally I have never had a leak. Here is a link for enough rubber for the table, but personally I floored my entire setup with larger rubber sheets. So worth it!

This is a picture of the completed frame. It looks more complicated than it really is. Take care to measure properly as these pieces fit together exactly.
Firstly, you need to cut off 3" of your aluminum tubing to make room for the legs.
4 45" aluminum pieces. Take care to leave exactly 1/2 inch from the end to the first hole. These are where the connectors are bolted.
4 24" aluminum legs with end caps attached. Once your frame is bolted you can screw a small .625 screw into the connector. You may need 1-2 washers per screw for a tight fit. (I did)
Cut and drill your pine boards and now you can attach them to the same connector joints.

As you can see, your plywood fits perfectly in the space. If you wish to be able to break it down quickly just let it rest on the framing and the steel support bar. Drill your hole for the ebb and flow fitting. I like a 1/2 inch deep counter bore so my fitting is flush with the table. I get near 100% drainage this way.

Here is a photo of the spray glue I used as well as the ebb and flow fitting. If you wish to glue the rubber I suggest installing the fitting first and folding the rubber into clean and manageable pieces. Start from the drain end and finish at the other end as seen in this photo.

Finally, just trim the rubber edges and you're ready to go! Hope this is helpful
