Since Pat Waite quit producting centering rings I have been making my own with the device below (see attached). This has worked just fine, but he limit is 5.5" in diameter. I am now putting all the parts together for my L3 rocket and I'm short two bulkplates and a CR. The rocket is using 7.5" LOC tubing and since the arc on a 7+" ring is pretty shallow I was just going to put 6 or 8 drill holes around the outside diameter and use a jigsaw to complete the ring cut out. But before I began to desecrate this nice piece of aircraft plywood in my workshop, I just thought I'd check, how do those of you that build large rockets do your rings and bulkplates?
