Mike as I said, cut at the groove and the top will slide in. If you can do that with a pipe cutter, great, the OP didn't. Not sure how you can do that due to the differences in diameter. Enough said, and I'm done on this one. Every one has their ideas and if you can use a pipe cutter to cut on the "grove", well, never tried it. I just use the dremmel and cut there.

PS: are you watching the Olympics? I think Russian is doing a very nice job.
