Help On Cass Main Mirror Hole

I have a homemade 12 1/2 Cass with a hole in the
primary to hold the diagonal mirror support. Once
while removing the support, it slipped aginst the
mirror chipping the edge of the hole. While the chip is shielded by the holder it has no
effect on the optics... I know it is there and it
bothers me. What method can I use to chamfer the
edge of this hole, thus smoothing out this chip?
This chip is about 1/8" wide x 1/16th deep and about 3/4 ' long around the edge of the hole. I would like to chamfer the complete circumference of the hole and blend in this chip. Anyone know how I can do this without doing more damage to the mirror?

Thank you..
