Hello Rick,
Let me welcome to LJs. I am sure that you will find being a member of this group to be both a rewarding and an inspirational part of your woodworking adventure.
Rick, questions about blades for Craftsman jointers have come up before but I just don't recall where the responses suggested finding replacement blades. I will look through here and see if I can find it. But if you want to re-post the question as a blog or forum topic it will get read by more members as opposed to posting it on your profile page.
Rick, I did a search at Sears Parts Direct and it looks like Sears carries replacement blades for your model.
Here is the web page that shows the parts list for your jointer. It looks like the cutterhead assembly is part number 53 and the blade is number 54.
