Done the same myself.
Such repairs will usually last years (decades?) for our infrequently started Ns.
Another ho-made "fix" is to pull the engine over a bit with the fan upon each shut down. Engines usually stop in nearly the same position upon shut down so ring gear teeth wear accordingly. Why not use some other teeth?
