What kind of saws do you have, eg sabre saw, circular saw, jig saw, etc?

What diameter holes are you drilling?

The piece of clear plastic has to be cut into two a terminal cup sized rectangles, then each's four corners drilled to make the mounting holes.

I have a drill. I have regular bits. I have no saw.

Here is how I did my speaker terminals. I can help if you want. I used a small milling machine to drill the holes for the banana jacks accurately -

I got most of the tools in the shop when I made this in the early 2000's. Now they are available for building speakers and other electronics -

Another way to build some one off projects is to construct the parts using JB Weld epoxy. I transferred the guts from a stereo push pull 300B amplifier prototype built by David Berning that a member of the local audio group owned to a new chassis . The way I did it, I needed a tube cage for the 6JE6 tubes used for the switching power supply. They have plate caps and I did not want access to the caps by prying fingers. I build the cage using strips of aluminum angle and perforated aluminum as shown in the photos below. Crude but effective. The strips that made up the bottom frame was first screwed into position on a scrap piece of wood covered with waxed paper. Then the perfed aluminum was cut and bent, then glued together with epoxy. Finally, it was glued into the base. After all was done, It was painted with Krylon textured black spray paint. Just another way to use basic tools to create a required piece. BTW, I don't have a brake to bend metal so I cut a scrap piece of MDF to size and then used a rubber mallet to bend the metal around the edges of the form.

Your cases remind me of the old Dynaco tube amplifier kits.
