I started a Cutter inspired rat. It's an octogat with ruger firing pins and extractors like Cutter used on his rat gat. Pics coming

Yes I have anodized a lot of small items but for this I had to use bigger tools. I used a welder for the power supply and made a tank from 6" aluminum pipe for the electrolyte.

very different. It creates a hard surface on the aluminum that is then dyeable. It involves putting the part in a diluted acid bath and energizing with DC for about 45 min.

Nice job, you probably saved over 200 bucks on that bearing.
