As there doesn't appear to be a tools section, unless I've had a 'word blind' senior moment.
I have a Ryobi table saw and cleaning the saw dust out of the innards notice on checking the blade alignment it runs very slightly off as though buckled should I stop using it ?.
Most of my cuts are carried out with the blad protruding 1 inch above the timber to be cut so lttle blade is showing.
I've check the drive shaft is doesn't appear to be that.
