    In my preparation for MHM, I noticed the AMW 75mm casing I borrowed is missing the “nozzle washer”. Can someone bring a spare that I can borrow? I’m hoping I could get it from Wildman but I would like to make sure one is waiting for me.

    I am also in need of a 1/2″ launch rod, preferably over 6′ long. I know my comments about not using rods but this is a special case for the Mars Snooper III. It wasn’t practical to use rail guides on it. I’m sure the club has one…

    Doug, the club most definitely has a 6′ x 1/2″ rod.

    Doug,

    I have both Pro-x and Loki 75mm hardware, likely have something that will work–is the amw a full nozzle or one that fits within a sleeve?

    It does fit in a liner but the washer goes between the nozzle and the snap ring. I estimate a 2.75″ OD and about 2″ ID and about 1/4″ thick. I think it distributes the load to the graphite nozzle. I thought about trying to make one from aluminum then reconsidered, what is the melting point of aluminum?

    1200f, or several thousand below exhaust temps.

    Doug, I have a 75mm nozzle washer for an AMW 75-6000 case. If that fits, you’re welcome to borrow it.

    I can’t see why it wouldn’t – at least with all the loki hardware I’ve seen (38, 54, and 75), the rings are the same size for all the cases in that diameter. I would assume AMW is the same way.

    Not sure I was clear, some of the pro-x hardward for instance have nozzle adapters, so less graphite used–sounds like Warren has you covered anyway.

    Thanks everyone. I’m not that familar with other brands other than Aerotech. I’ve used AMW on a few occasions when Jim was still renting. The guy I borrowed it from says Tim is suppose to send him one (it was missing from the set he bought). I was just estimating the size from the place it is suppose to go… Thanks again.

    No problem Doug. I’m not using that AMW 75/6000 case this launch so I made sure I threw the ring in my range box. Just see me when you get in and I’ll have it.
