Well, the Crown 10" Dovetail saw arrived and initially everything was good, but practise and the real thing are two different animals. Over this weekend I have cut about 50 dovetails and to be perfectly honest, although they were getting better I was not happy with any of them. When I looked at the saw cuts, mainly in the pins, every one of them had a right drift from top to bottom, some, I think dependent on which saw stroke I finished on had a pronounced "J" shape (but mirrored to the right). With one set to go I decided to try and improve the cuts with more practise, but whatever I did I got this problem. Never to the left so consistent. I thought I would make a saw guide that guided the saw at 8 deg and straight vertical and try as I might the saw would not track down the line. It was literally pulling itself to the right. However much I tried to steer the cut I could not stop it. I could hold the saw at any angle and still the right drift. In desperation I took some of the aggressiveness off of the right hand set with a few light rubs with a diamond bench stone and Low! an improvement! well nothing venture nothing gained and another few strokes and the track gradually became straight. I also noticed the the cut was not as smooth as it should be; now bear in mind this is being done looking through my new best friend - A jewellers type head mounted magnifier! A single rub over on the left side and tried again. Now of course the saw feels tighter in the cut because of the mods, but it tracks perfectly straight. I can split the line every time. I will still use the cutting guide for the last set, but at least I know that the result will be good. So I may not have a perfect technique yet, but I was being made to look worse by the saw. So now it's all down to me!!!!
