Personally I don't believe in gluing together sawn wood. The edges should be machined on a jointer prior to being glued together. The joint depends on the wood being tightly together and the coarseness of the saw cut prevents this. If you are going to do this you need to eliminate the gaps between the boards. Otherwise a lot of pressure would be needed to force the wood together. How ever much pressure needed to force the wood together is how much stress the wood will be putting on it to pull the joint apart. The best way to make a glue joint on a table saw is to make a sled to keep the wood straight against the fence. It also helps to use a really sharp blade. Any deflection of the blade when ripping the parts will cause the joint not to be straight.
