Maybe some of you can tell me what to check? As of recently, the blade in my excalibur does not hold the tension. I.e. I tighten it, it makes the appropriate pling sound, I start sawing and then it wobbles, so I loosen the plastic tension switch and now the blade make a bow/arch, even though the screws in top and bottom are still tight. then I loosen and retighten the top screw and the game starts over again.
I have retightened the counter screw/bolt or whatever it is called that opposes the tightening screw in the top - to no avail. Today while cutting poplar 3/4" I broke three #7 blade and one #3.
any ideas what needs to be adjusted on the saw?
