I've been too afraid to tear any of mine down. I've heard it can be very hard to put back together.
That is true. Chances are there will be some mumbling, groaning, complaining and if you use such words, well..........
There will be some mistakes made which don't require you to back up a step or two. They require you to go back down to ground zero. LOL. Believe me. I did that yesterday. Some things have to go in FIRST.
But, the second time, it went pretty smooth so within a short time it was all back together again and working fine.
