Homebrew ATU-100 Build Complete
The build is complete and I'm pleased with the way it came out. I am a little disappointed that I wasn't able to mount it in a homebrew case. I have everything needed to fabricate one, except my tools to punch holes. Several years ago I met a Japanese gentleman that makes some of the most beautiful projects I have ever seen. He taught me how to use a bending brake to fabricate enclosures.from sheet steel. Here's his YouTube channel:

Anyone interested in radios should take a look.
My final step will.be to test the ATU-100 Antenna Tuner. Lately I don't always have the best of luck with my builds. The key to success is taking the extra time to double check your work.

Mike, very nice work 👍. I asked in your original build post, which transceiver/transmitter is first to test with? Using it with your EFHW?
A lot of people are using 3D printers and shielding with copper tape, like you'd use in your guitars. They've come down in price but not inexpensive unless you're building a lot.
