Rotory cutter blades wobble

[toddt73]

I removed the blades to clean debris and lightly grind a few nicks out. Problem is, I've tightend them as much as I could but the blades wiggle up and down just a little on the shoulder bolt. Is the "shoulder" on the bolt what is doing that so the blade can be tightend without the blades binding? I didn't think to try to wiggle the blades up and down before I removed them. I feel like it's supposed to do that, but with such a crude, powerful and dangerous impliment, I am questioning myself. I am new to all of this and need to be extra careful. Sorry if it is an obvious answer.

They'll straighten out when you get it to full RPM.

Yes, they will wiggle.

Yes, they will wiggle.

Thank You. I figured as much, but as mentioned, my confidence in my judgement is a little low. I appreciate it.
