Oregon 410-120 vise is garbage

[Tree Tater]

I'm really getting aggravated with the vise on my Oregon 410-120 bench grinder. It won't grip chains and is causing me to lose so much time fiddling with the vise trying to get it to securely grip the chains....

Any insight to what the issue is and how to fix it? Really p#$&3d off at this point.

Can you post some pictures?
There should be no clearance between the rails when the lever is moved to the closed position

How do you adjust it to lock up that tight. Or can you. Mine is having the same issues.

I HAD that issue with one of my grinders, I say had. I removed the clamp jaws entirely, filed them smooth on the inside and adjusted the cam lever to clamp tight.
The clamp jaws are stampings with no extra attention to burrs or anything else, btw and the cam lever is adjustable btw. Actually, the 100 buck Vevor clone I also have clamped tighter than the Oregon did from the get go.

I also removed the 2 threaded end screws and shortened them about 1/16"

In fact, I think the Vevor clone is a better grinder, especially when it comes to the depth stop. Amazing what the Chinese do when copying something and then selling it for about half price.

The Vevor has all the same angle adjustments including the 10 degree base offset.
