I am working on a project where I need to mount a speaker inside a pre-fabricated 8” steel sphere. The cutout diameter for my speaker is 5.25”.
What is the cleanest way to cut the 5.25” hole in to the 8” steel sphere?
I have access to a drill press, a Dremel, a hand drill, and some files. Open to buying other tools for the project if they’re not super expensive, but don’t really have access to any water jet / laser cutting thing.
Here are my steel sphere and speaker components for reference. Thanks!
