WELCOME TO THE FORUM
Hey, I am building a very nice file cabinet and have everything already built and am now at the sanding stage. The only problem is that I realized that I did not plan for the hanging rods that the hooks on the sides of the files hang on. The draws are already built so I cant instal rods directly into the wood, And there is no clearance at the top of the draws for something like this to work: http://www.rockler.com/product.cfm?page=212
Please help me, I would like to think that I did not spend all of this time making a file cabinet that cant hold files.
There's an easy solution to your problem. Solving what you do depends on the size you made the drawer. The inside of the drawer must be wider than the metal tabs on the Pendaflex® type file folders. The inside height must be enough to clear the tabs of a file folder so the drawer opens and closes without rubbing. Also allow enough height to add index tabs to the top of the folders if you desire.
You can use 1/8" x ˝" flat metal bar stock
for your hanging rails. You can use the table saw (1/8" saw blade kerf) or can be done with a hand saw, or jig saw, and cut 2 slots in the front and 2 in the back of the drawer pieces to a depth that when the ˝" bar stock is tapped down and the file is hung on it, an empty file folder won't rub on the bottom of the drawer.
Once you have determined the distance between the slots (for letter, and for legal), a one time fence set-up will do the slots by running the drawer upside down through the saw. This has to be done as the drawer is already together. But, the good news is, if you set up right, it comes out perfect.
The length of the bar stock should be the length of the drawer (outside measurement). The slots can be any depth, and the file folders slide nicely on 1/8" stock. That stuff is pretty cheap, and I think it's sold at the box stores in the hardware section.
If all else fails, and there is enough room inside the drawer for clearance, you could use a drawer rack, like this
