How to Build a Hank Drum

Step 3 Remove Welded Ring

Next, remove the welded metal ring attached to the tank bottom. Try to avoid damaging the tank as this is where your notes will be cut. Chiseling or manually stressing the joints should allow you to "de-ring" the tank very quickly. File down any remaining nubs.

I assume a metal grinder could also (carefully) be used to get the ring off, right?

Absolutely.
