Resolved - Ok learned from my after the fact geek squad that:
1. You dont have to remove the Woodruff Key, cam key, keyway whatever to take the gear off. I Did not know that and in my efforts to remove it scewed it up.
2. That the chain can be removed from the lower gear without removing the gear.
3. Because I had scored and chunked the key it had to be removed but could not be removed untill the ther gear was off. This required filling away the nicks on the key untill the gear slid off.
4. With a chisal and hammer the key slid out.
