Low stinger shot: golf?

I am wondering how to hit the low stinger that Tiger Woods has made so famous. I have tried using a 3 wood and 4 iron for this shot. For the three wood i place ball in middle of my stance and the four iron just slightly back of middle. When i swing through i keep my hands way ahead of the clubface to deloft the club, around my front thigh at contact is what I am trying for. I cut off my backswing where my wrists start to hinge and I do the same in the follow through of the swing. I never get the ball flight that I expect though on this shot. To be honest, instead of hitting a low stinger my ball comes off the clubface barely just below normal height and then balloons up into the air higher than normal! I dont understand what I am doing wrong. Am I attacking downward into the ball too hard. I play a draw on this shot to try and shallow out my swing plane because playing a fade on it seems to multiply the problem. I do attack down on the ball hard on normal swings. I am most certainly not a sweeper iron player. Do you guys think that this is the issue, or are there other swing flaws that could cause this low stinger to balloon up into the air so badly? Any tips on how to hit this shot consistantly would be greatly appreciated. I would love to take this shot off of the driving range and onto the course!!!
