“We drew a circle the size of the post holding the copper against the post top.
Cut the copper 3 1/2” inches larger than the circle. Marked off about 2 inches indicating where each of the bends will be formed. Started bends by placing copper circle on two boards secured about 6/16 space between them.
Starting on edge, we pushed a piece of angle iron slowly from outside in on 2 inch lines forming a coke bottle top effect.
After making a complete circle, trimmed side even again as they change during this faze.
Fold outside lip over making for a smooth edge and squeeze with pliers gently.
Place over post and complete bending using squeezing force and hammer
Lift off and push sides in a little more.
It should now fit very snugly.
Put quite a bit of glue on top of the post. Placed copper over top and push down.
Tap around sides with the hammer and let dry. We used liquid nails construction adhesive.”
