I'm putting together my Grizzly G0661 table saw. I also just purchased a Super General blade. The blade on the saw was bolted down quite tight. I actually bent the wrench that holds the arbor trying to get it off. I had to use a real wrench on the arbor side and a 1/2" socket to undo the bolt! I looked at the arbor and noticed some of the material had deformed a bit around where the arbor wrench goes. Is this going to be a problem? It seems the arbor material was a bit "soft". I was able to get the new blade on and tighten with no problems. Thanks!
