I just used my lazer...... 
yeah, pretty much cut half of the penny away, leaving only the remaining half, first a grinder then a file then sanding. oh and I did crazy glue it to my hand this time while repairing it, really had to tear it off because I held it securely for several minutes before I realized I got some glue on my hand too
unfortunately I couldn't just leave it glued to my hand... maybe I should have, but I didn't, it was glued to the wrong hand anyway
playing with this thing today while fully awake again I can see now that this penny actually makes this whole toe of the mod much much stronger. this ring breaks because it is thin and hollow and it doesn't take much force to compress the roundness, causing it to deform and crush and crack. the penny winds up keeping this round form reinforced and resisting the ring from crushing so no cracking as the O compresses. before I could have snapped this ring extension off by just squeezing it with my fingers if I tried hard enough, now it feels dead solid. it has to help quite a bit I guess. even though it's been broken twice already I believe it is now much stronger than it ever was, even before the first break.
