Then, using a boron machine, he removed all the burrs remaining on the bank after opening the lid.
Next action. there was a hole in the center of the bottom of the can.

The guide pin drill was made of a threaded rod, one edge is sharpened under the cone.
Attached to the bank with nuts through a previously drilled hole.
The bottom of the can is quite flexible, so the author poured it with hot glue from a glue gun.
Additionally, he also processed the nut fixing the drill so that it does not loosen.
That’s it! The hole saw is ready! Told ya. that everything will be simple.
