Some how between the machine shop and my house I chipped the front edge of the harmonic balancer. It's on me he painted it all, and there's no paint in the problem area!
So what to do?.... The pic doesn't really show that the whole front edge broke its about 3/8's long. Can I grind it's smooth, or is it now junk? It appears to be some type of pot metal?

Here is another angle.
How do the pics work on this site?

Not an expert on this particular part, but in general blending sharp edges and radiusing will keep it from cracking, but removing material from a balanced rotating part would require rebalancing. That is what I would do no matter how little was removed. 6000 rpms is not the ideal time to find an imbalance of a rotating assembly.

Pretty sure the one I have been using for the last couple years had a similar nick out of it...has been working fine. Not saying thats the best thing to do, but it wont automatically self destruct the first time you rev it either.

No doubt it may work. Well balanced parts will last longer and cause less issues throughout the entire vehicle. That little shake you feel at idle is imbalance. The rattles in the back are imbalance. Some can't be avoided, or it is not economical to fix some things anyway. Up to the discretion of the user. The ol Cha-evy tree-fidy fixem upper style is tried and tested by rednecks all over the place... It will probably work for awhile, but how long is the question.

Mines been chipped just like that for atleast 5 years and has been on 3 separate motors, no problems.

get rid of any sharp edges and use it. No problems.

That's it? Use junkyard ones worse then that all the time without issue.
