Actually, there is a trick. I saw Chris Kvale demonstrate at a Cirque several years ago. You cut the stitching on the casing a few inches at the valve stem. Cut the old tube in two. Take the new tube and cut it in two(!) near the stem. Fish the tube around tubular (using the old tube). The last step is to use patching cement to glue the two ends back together. Chris used something like a double lap by everting one tube and folding it back over the other. I can't remember the details but expect that it wouldn't be hard to replicate. It was very cool watching him work.

I seem to recall that there a video of Chris' demonstration. Any one have a copy of the video?
