Hi, I have recently been given a craftsman radial arm saw from my wifes uncle. The blade has a wobble sorta.....when you spin the blade by hand you see a very noticeable wobble, about 3/8". When you start the saw up you can see this same wobble until the saw gets up to full speed then you cannot see the wobble anymore. If i cut a piece of wood it cuts clean and straight 90 degree cuts. I've also cut a groove into a 2X4 and it's cut strait and at a 90 degree and the groove when finished is the same width as the kerf of the blade. It would seem to me by what I have tried is that once up to full speed the wobble in the blade goes away. When I line up the blade to do a cut the blade lines up where I want to cut but then once I start the cut because of the wobble of the blade it cuts off the line somewhere random in this roughly 3/8" area where the blade wobbles before seeming to straightenout once up to full speed. I have tried interchanged the blades with those in my table saw and mitre saw and there is no wobble in the blades in those saws so it's not the blade. Any ideas would be greatly appreciated. BTW this is a Craftsman 35th Anniversary Limited Anniversary Special Edition Model number 113.278541C. Hmmmm, do you think the wobble is part of the after affects of the celebration?????
