I don't currently have locs, but I was locked for 7 years and cut them off in 2010. I will be locking again later this year though. I did everything myself from beginning to end. I started with two strand twists and maintained by latching with my fingers, I didn't use any other tools. Sorry, I don't really know how big my parts were, but here's a picture that gives you an idea of what size my locs were after they fully matured. They were about 6 years in this picture.
