Patching up bored cork rings

I stopped by the hardware shop the other day to get a hole puncher for the job. A few cork rings was "sacrificed" for project.

Using the hole puncher, I punched holes on the cork rings to make the cork plugs to seal up the bore. Here's how the process look like..

Some cork plugs made by the hole puncher.

I used TB III to glue the cork plug to the ring. A dab of TBIII at the hole and push the cork plug in.

My patched cork rings are ready for its' next process.
