Tony, there are two factors I emphasise when sawing, whether it be dovetails or tenons, and all else ...
1. You have to see the lines clearly. That is why I use blue tape when transferring dovetails. If you have not tried this, then do so. There are articles on my website. Here is one: http://www.inthewoodshop.com/Furniture/HalfBlindDovetailswithBlueTape.html
2. Saw against the line. A fine knife line, that is. The ideal is to just see the edge of the line remaining.
I'll add two more ..
3. When sawing, saw to two adjacent lines. That will keep you tracking straight. I have never practiced sawing. I just saw to the lines.
4. Go for it. Don't be conservative and saw away from the line. The more to tune, the greater to chances of creating an off-square wall.
