I would like to make a fire proof safe, Does anyone have a CNC Plasma table?

Safes for personal belongings and documents on amazon don’t really strike me as “fire proof” even though they are advertised as such.
From what I can gather, the real deal fire proof safes start at 1000$+

I set out to make one myself for hopefully alot less and found this YouTube video of someone doing so.

The maker space currently doesn’t have the tools required, a plasma cutter for me to make such a project.

I was wondering if anyone at the maker space might have access to a plasma CNC table, and would be willing to work with me on this project to cut up some 1/4’’ steel to make the main carcass of the safe.
