I thought I'd post this to help anybody with a similar situation.

I've bought most of my kegs used. I get them for $20 - $30 through sites like craigslist and offerup. Usually they need a bit of work such as heavy cleaning, o-ring changes, and relief valve changes.

One keg was very strange. It's an AMCYL MODEL K2009(2). Any lid I tried on it would not form an airtight seal. It appeared that the flange was too narrow.

My solution:
1. I ground the flange with a 4" right angle grinder with a fine sanding pad.
2. I then used a carbide burr attached to a drill.
3. I then used a 3/4" drum sander attached to a drill.
4. I then used a cup brush attached to a drill.

Step 1 removes the majority of material.
Steps 2-4 are for smoothing out the sharp edge created by the grinder.
