The solid corks that will not be cut are first put in the approximate location.
I use a longer punch to work with the corks, but a pushpin works nicely to lift the corks out for applying the glue.
This brand of hotmelt glue works well. Purchased at Walmart.
Lift each cork out by placing the punch it the top, which gives you a good idea of where to apply the glue.
Applying the glue to the bottom of the cork.
After all of the solid corks are glued in place the others can be fitted in place.
I use a band saw for cutting these corks, but a utility knife or exacto knife would work also.
Fit and glue each one in place.
These are the hardest ones to cut, so its good to have a few extras.
All glued in place and ready to use as a hotplate.
