I recently purchased a Diablo finishing circular saw blade, but I accidentally twisted off the middle part mistakenly thinking it wouldn't fit my Ryobi saw. After realizing that it was just sitting in place while the saw spun, I put the piece back in and tightened everything up. Now, it seems to be spinning fine. However, I'm going to be building a closet carcass soon and need to rip some long pieces of birch. Should I return the blade, buy a new one, or can I trust it to be reliable as long as the middle part is securely back in? Thanks in advance for any advice!

I wouldn't worry too much! As long as everything is tightened down, it should work fine. The blade won't go anywhere if the bolt loosens up; it'll just spin on the shaft. I’d say go ahead and use it.
It's not just a simple spacer; it's actually a laser-cut centering guide, and if it’s not centered properly now, it could affect how well it cuts. Even if it doesn’t come loose, it won’t perform like you expect from a finishing blade. I recommend tossing it and picking up a ripping blade for your birch project. Also, don’t try to return it—they might not accept it back since the piece was removed, and you don’t want to leave a faulty blade for someone else. Just ensure you get a blade designed for ripping, with fewer teeth engaged at once. It'll make cutting fibers much easier!
Honestly, I'd be cautious about using it. You might want to consider returning it since that part is crucial. If I were to vote in a forum like AITAH, I’d say returning it is the way to go after that mistake.

Could you explain more about the last part? I’m not quite following the details, and a reference video would be super helpful!
