The shelves in all our kitchen cabinets are supported by plastic supports which look similar to this:
They were put in 30 years ago when the place was built and every once in a while for no apparent reason other than age, one of them snaps off where the peg joins the support, leaving the peg stuck in the hole in the sidewall, flush with the surface.
Years ago I used to drag out a power drill with an assortment of bits and drill out the peg so I could insert a new support.
That worked, but spewed plastic shavings around and once I lost control and let the drill break through the sidewall of the cabinet.
That's when I thought up this safer way.....
I just take an appropriate size sheet metal screw, hold it by its head with pliers and heat the tip to nearly red hot with our small propane "kitchen torch" and then melt it into the broken off plastic peg. I step back and sing God Bless America to myself once while the screw cools down, then grab the screw head with pliers and pull out the peg.
BTW, how many of you know there's an opening verse to God Bless America that's rarely sung these days?
It goes:
While the storm clouds gather far across the sea, Let us swear allegiance to a land that's free, Let us all be grateful for a land so fair, As we raise our voices in a solemn prayer.
God bless America........
Those of us old enough to remember Kate Smith would have heard it, she always started her singing of God Bless America that way.
