The bows consist of three 3/16" dia rods that fit in the clips and one 3/32" wire that is held to the roof by bend tabs in a roof brace, no clips needed. see photo 1. the 3/16" rods fit snuggly in the clips I made for them. An Elky needs 6 clips total.
All bows are longer than the usual 48" cold rolled rods available at Home Depot so I lengthened them as shown in the second photo. I ground long matching tapers on each end of two rods then laid them on my welding bench and brazed them together and ground the joint round.
