What kind of blade do you use? A reverse kind of blade? Pretty normal, just hold the wood a bit more.
Reverse Blades have teeth facing up to make the backside smoother.

Or are you using a spiral blade? in that case is the blade mounted upside down. Mount it correct and the cutting will work much better.

We need a lot more information to help. Type of saw, type of blades, type of wood and how thick is the wood?  :)

Yup.  More downward pressure if you're using a Reverse toothed blade and make sure you've got it in right side up.  Very small blades (i.e. 2/0) can be difficult to determine which way is up, so look closely!  Plain spirals are easy to determine, but I guess there are some with reverse teeth now, so just make sure they're right side up!

"Chatter" is caused by the blade lifting the wood as the blade moves.  If you are not using a reverse tooth blade, check to see if you have the blade in upside down.  We all do it from time to time.  That could also account for the cut not being as smooth as it was before.  I would suggest you order a variety pack from Mikes workshop.  That will give you a feel for the types of blades that you would like to use.  Buying good blades will make a huge difference in your work.  They are actually less expensive that the cheap blades you can buy at the hardware stores and far superior in quality and sharpness.

contact Mike: http://www.mikesworkshop.com/blades.htm

He sells Flying Dutchman Blades, which are one of the top blades. Working with them blades will improve your work much.
He will send them to you and has great service.
Alternative are Olsen blades, which you can get at several places (I guess cause I'm not living in the US).

So I came home from work anxious to try the tips you all shared with me. The first thing I would do was check the direction of the blade. I was sure I checked it when I put it on the saw. Sure enough if I did I must have done it standing on my head, cause the teeth were pointing up. Things are better again. Thanks for your help.

You will absolutely see a marked improvement in the cut if you switch to a good quality blade!!!  Several brands to choose from, so give 'em a try!  I guarantee you like the difference!

When I first got my craftman saw I used thier blades.  They did exactly what is happening to you, except maybe you do have the blade upside down.  Craftman blade are cheaply made and cost are high.  Like the others have sugested, call Mike and he will help you.  He sells FD blades.  I use olson blades and have really good luck with them.
