Looking for a replacement ring for a Giant Leap 75mm Classic SlimLine motor retainer

I thought I would ask here to see if anyone had one available. GLR doesn't even sell a classic motor retainer bigger than 54mm anymore. I have a Slimline tail cone that is mounted on a 4" airframe and retains a 75mm motor. It is my L3 rocket that I built a number of years ago. I am finally going to do my L3 cert flight in 2018 and I can't find the spacer ring. I have the retainer clip and got spares on that from GLR just a few months ago, but they didn't have any of the spacers.

Let me know if you have one that you would be willing to part with. Hopefully not too expensive...

Thanks!

I cut a slice off an airframe section [motor mount] to make one. Careful cutting required 'cause it's so thin, but patience and it easily doable.

Hi Jim, Thanks for the idea. I can certainly make something, but that all takes time and I was actually trying to save some...

best regards, Steve

Go here: https://www.mcmaster.com/#retaining-rings/=1a5rahj. Pick something close to the 75mm internal dimensions and likely you will be fine.

Thanks "Big Bucks", I already had taken a look at McMasters. I already have the retaining ring. I need a 80mm OD 72m ID 1.3mm thick washer preferably in steel. McMasters has nothing I can use without having to modify it and as I said, I am trying to save time...

best regards, Steve
