Best tooling ever. Check out the Mach rings [URL=http://s980.photobucket.com/user/d9inger/media/DSC_0692.jpg.html][IMG]http://i980.photobucket.com/albums/ae286/d9inger/DSC_0692.jpg[/IMG][/URL]

Why are YOU regulating which comments are posted. WOW!!! I paid for end burner advertised! And got a nipple machined WAY wrong. 1 inch nozzles formed 1 inch inside the tube making for way less space for fuel. Not standard. Wanted the right one shipped to me. Nope, somehow it's my fault and I am supposed to find something to fit over to make it correct. Horrible experience followed by horrible customer service

I own Rich's 1" and 1.5" end burner sets, and they are perfectly machined for their intended use. My only reservation is the fact that the Kn of the sets are so low, that even meal "D" has trouble generating decent thrust. My solution was to adapt the 1" nozzle forming set to a 1.5" tube, to get the minimum Kn for BP of 44, on an end burner rocket motor. Upon making this adjustment, I got a decent performing (4-5 lbs thrust) motor that burned for 15 seconds on about 200 grams of fuel. Recommended, with the mentioned modification, or the use of whistle mix, at your own risk (not tried).
