Saw blade vibration?

[chopnhack]

For the many of us using WWII blade in our bt3x: Did anyone notice a lot more vibration when switching to the WWII compared to the stock blade? I attributed it to the heavier blade can anyone else weigh in? It still cuts really well, just curious.
Thanks

no, not at all.

Hmm...I guess I will have to check my runout.

[RodKirby]

Absolutely not.

Mine works fine. Suggest you loosen yours up, turn it 90 degrees in either direction on the arbor, and then re-tighten. Don't over-tighten.

I'd typically expect less vibration. Be sure it's not too tight, and definitely check for blade runout.

Thanks all, it brings to mind another question now...
With an expensive and dangerous blade whizzing around at a 100 miles an hour, just how tight is tight enough?
thanks in advance.

Not very tight. A left-hand thread is used because the rotating blade tightens it rather than loosens it.
I just turn the nut to finger tight, bottoming out, then use the wrench to turn it about another 1/8 to 1/4 turn.

too tight can warp the blade making it wobble and cause other problems. No need for it.

Exactly what I do. Probably much closer to 1/8 turn than 1/4 turn ... I just give the wrench a short, firm pull and put it away.

Awesome, thanks fellas, hadnt thought about the fact that it is a left handed thread!

You might want to try the stock blade again to see if again there is no fibration, just in case something else is involved. If there is none, you have a problem with the new blade.
Good luck
