Spacing problems with connected font

I'm working on a connected script font and am trying to limit the kerning as much as possible. To make the characters connect smoothly, what I did was to use the entrance and exit strokes of the "r" and to paste them on the other characters. However, this sometimes creates spacing problems, since some characters are narrower than others. I've tried to change the angle of these entrance and exit strokes, but that doesn't make it any better. 
Does anyone have any suggestions on how to solve or maybe make it less of a problem?
