thats not how u fix a broken edge
go to a shop
or
1. get a new piece of edge, and epoxy
2. cut down edge to the proper length.
3. cut base around broken area in a smooth arc around the spot
4. after roughing up thoroughly, mix the epoxy in a cup
5. put some epoxy in the area where base/edge is missing (makes it easier to place edge in for me)
6. fit new piece of edge in to missing area
7. use tape to block the epoxy from spilling out the side
8. poor epoxy on to fill the hole
9. Let the epoxy set completely
10. use a file to scrape off any excess epoxy.
u are done
