Joe,

You have a point, but if you don't want to go through all of the trouble of doing that you should look at what's available at HLI.

I used to be able to find and buy stuff like this 30 years ago. I didn't think anybody still made instruments like these. They are molded in black plactic with the knobs, screw heads, and bezels. They even come with the clear glass.

Why go through the trouble of building them if can buy them like this.
