Steerer tube gouged, safe or trashed?

Aluminum steerer tube on an '87 Trek 560 Pro. Gouge is 0.2-0.3mm deep, tube walls are 2.5mm thick. It'd be covered by a shim and stem (1" to 1 1/8").

I weigh 120lbs, bike is for road use. I hit an occasional pothole and do ride some bumps here and there in NYC but nothing super harsh.

Is this still safe to use or should I look for a new fork?

Thanks in advance. Excuse the wonky top cap, it's not bolted in.

I would keep using it. It does not appear to have structural damage.

The gouge looks to be within the stem's clamping area. Is this so? If so then there's less to be concerned about as the stem's clamp will act as a sleeve and the bending force will concentrate at the stem clamps bottom. Still periodic monitoring is prudent. Andy

It's smack in the middle of where the stem will clamp. There will be a shim too because I'm converting 1" to 1 1/8" so, extra "reinforcement" I guess?

I'll definitely keep an eye on it.

Stay safe and healthy out there!

Due to its location, the forces on it are small and likelihood/consequences of failure are slim. I am pretty conservative on such things and it would not give me any heartburn.
