Cut my first barrel tenon threads today.

Looking good! Cratex makes some abrasive rubber 'sticks' that are great for cleaning up threads. I mostly just use the course (dark green). I'd slide that barrel into the chuck a bit. Looks like everything worked out, but that's a lot of stickout unless you used tailstock support.

I will keep that in mind for next time!

On a side note, I got the nicest turning surface finish when I accidentally took off 0.020" at 700 RPM. I got the nice blue chips that we all love to see! I'll have to find a bit that gives as nice a finish with light cuts.

Tony.
