Everyone says to toss a blade the second it kicks back, but my old Skilsaw taught me otherwise
Last Thursday a knot in a 2x10 pinched my Skilsaw and it jumped about 4 inches before the guard caught it, so I pulled the blade, checked the arbor for runout, and it was dead true, and now I'm wondering if my 6 month rule for swapping blades is costing me money for nothing.
Did you ever check the arbor on the new blades you've been buying to see if they were true from the start? I read somewhere that a lot of "worn out" blades get blamed for wobble when the real issue is a bent arbor or a bad bushing, and runout on the saw tells you way more than a calendar does. Six months of cutting soft pine is nothing compared to a couple weekends of hard oak, so a flat time rule never made much sense to me.
