Acid Washed

28 02 2011

All photos.

I just disassembled and acid washed all the parts for the coil former and electron gun. This degreases and cleans the parts.

I used a 15% HCL solution.

The aluminum started bubbling, so I didn’t leave it in long. The Stainless and ceramic I left for 15 minutes.

The parts will dry overnight.
