so notch it like a side ways triangle?
When i was imagining the wheel turning more and more cutting into the arm that it would be one hell of a notch. I felt that grinding it that much compromise the structures integrity.
I would like to see a picture for reference of how much you had to take out.
I'm not going to tell you that it bad or anything, just curious that maybe its not that much material that i have to remove.
If you cant post a picture that ok maybe a general guess 1/2 inch cut?
I appreciate and look forward to your comment.

EDIT i just re read your comment if its just curled lip...I can do that
Thank you
