I don't know if I can be of much help, but I will tell my experience so far. I ordered this a few weeks ago and set it up, but never got around to trying it until a few days ago. The first time I used it I found the finger bar somewhat difficult to move back and forth. I made some through dovetails following the directions in the manual. The dovetails came out somewhat okay, but the pins were less than acceptable. I then called Leigh support (highly recommend them!) and they gave me suggestions, including pages in the manual, to improve set up. I then asked my wife to help me and with her reading the manual and giving directions, we got it set up better. We then made a few dovetails and pins to form a box and it was better. The next day I went out and did it again and the results were better yet. So, I think set up is essential and then practice, practice, practice. I am going up to Kalispell today and buy some hardwoods to practice with.
