Stray pieces of thin walled tubing are cut from various diameter scraps to use for
cutting holes in clay - such as drainage in flower pots and planters. The aluminum
piece near the center is from a scrapped lawn chair frame! The rest are oll from
offcuts out of plumbing projects. The largest are nominal one inch shower curtain
rod, 1 1/4 and 1 1/2 inch pipe for sink drains. Most have one end cut at an angle to
ease cutting through the clay. The two largest were too short to allow the angle cut.
