To e-mail, I've figured out, click on the thing that says (No Name).  If you have any questions about the trap, I can send you a diagram if you e-mail me.

It's a good idea, but chipmunks are pretty smart.  I have constructed a lot of live traps.  You could just "dispose" of your catches after you got them, but the workings are simple.  First, make a cage out of wire mesh, leaving one side open.  Then, make a platform out of a really thin piece of wood or use corrugated cardboard.  Put the platform in the back of the cage, then attach a paper clip to one side and make it stick thru the mesh, and attach the platform in the back to the bottom of the cage with paper clips, too.  Make a door out of wire and attach it at the top with some wire "hinges," then attach some rubber bands to it and the inside of the cage to pull it shut.  Use a piece of bent metal stripping as a latch, so it can close over it, but the stripping will click back up after the door closes.  Finally, attach a string to the door and tie a paperclip to the end.  put down a piece of wood for the clip to rest on, and hold it to protrude over the wood towards the bent paperclip on the platform.  To get the string to curve around to work that way, you will need a piece of wood attached several inches from the back of the trap with two nails protruding from the side to string the string around.  Stick the platform clip, which is bent, in the other clip, so when the platform goes down, it pulls out from the string's clip and lets the door close.  Lastly, bait the trap.   E-mail me if you have questions.  Another method to catch chipmunks is to find the second entrance to the hole and put a milk jug's open end in the first.  Stick a hose down the second hole and turn it on.  The chipmunk will run straight into the jug.  One of my friends' grandma does this, then beats the life out of the thing with a blunt object, while it's still in the jug.  I think it's a good idea.  Wage war upon the chipmunks!
