I cleaned the 5/16"-24 thread cleaner that I previously machined and a 7/16" socket in acetone. I rinsed the paint off the 7/16" socket with the acetone spray bottle before putting it alone in a 100 mL beaker with acetone and sonicating for 3 minutes, replacing the solvent, and sonicating for another 7 minutes. I sonicated the thread chaser and socket in the same beaker with isopropanol for 10 minutes.

I used the thread chaser on a few holes on the LFC Input Vacuum Cube Top Flange, but the threads did not seem greatly improved. Either we just power through and hope the threads are actually fine with the silver coated screws, or we re-tap the threads. We have a 5/16"-24 tap, but I think we want some slightly nicer ones, including a bottom tap (which I don't think we have) to reach the bottom threads.
