Has any Ex flyers had problems with your nozzle being a degree off angle or more. Either on a launch or a test stand?

Im very careful to drill the nozzles I have strait. Any of the bigger ones I need of I have done on a lathe. besides I can have ANY size pretty well on a lathe done vs specific sizes of a drill bit.

I’ve never really encountered that problem, though I can see that if you did do one on a lathe that if you turned the OD down and didn’t drill out your throat before re-chucking to turn the other face down how you could be off.

I have had a couple drilled slightly off center as well as a couple with slight off angle with very little ill effect. Those nozzles where only used on the test stand. I have not flown one in a rocket.

We are Good to Go with our scheduled and approved launch on Saturday April 5th and Sunday April 6th, from the North Site, subject to change – Mostly cloudy and High Winds predicted. Range and waiver should be active by 9AM on Saturday. The Pawnee National Grassland remains fragile and dry, so extra precautions are in order. Please stay on the authorized roads and please don’t park more than 100’ off the road at the flight line.
