A few things about re-wiring in general.
Electrical tape often comes undone in a couple days. I'm going to use wire nuts to re-connect wires wherever I crimped and soldered wires together and applied electrical tape over the connection, which I can do fairly easily because I have plenty of slack in my wires.
Patience is a virtue when re-wiring a medium to large size layout. IMO, it is a big mistake to rush a re-wiiring project. I try my best to keep my wits about me and remain ruthlessly rational throughout the project.
It's a very good idea to make a diagram of the re-wiring you want to do. That was a great idea someone else shared on this thread.
Take your time to carefully label the wires so if any get disconnected, you know the correct way to re-connect them.
Don't give up if mistakes happen early on and/or the project seems to take forever. For me, the beginning was the hardest part. Later on, you get into a good routine and find that the project is moving along more quickly than it did at the beginning with much fewer mistakes.
Get good equipment like a good soldering gun. I recently spoke to a Forum member with a great layout who recommended a Weller Professional D 550. I got it and it works great; much more powerful than the prior soldering iron I was using.
