Versatile Two-Channel Pinch Weld Puck

This is a very useful and durable pinch weld puck, offering a wide and deep channel as well as a shallower and narrower channel running perpendicular to the 1st channel. It is robust in diameter and depth and will last many years. The pucks are 3 1/4" diameter and 1 3/4" tall. The deep channel is 3/4" deep and 3/4" wide at the top, narrowing to 7/16" wide at the bottom of the channel. The shallow channel is 3/8" deep and 9/16" wide at the top, narrowing to 7/16" at the bottom of the channel. While the bottom has a ring, the middle and outer sections are level with the bottom of the puck.
