I don't have the M- designations of the 'standard' HE and HEDP 40mm rounds I am thinking of offhand, but does anyone hapen to have some dimensions or even better yet some line drawings or CAD drawings of common 40mm rounds?

This isn't for anything underhanded, I just have the opportunity to use a CNC lathe for my CNC class and would like to turn some dummy display rounds out of nylon sotck for my 37mm RPB launcher.

Any info would be appreciated, otherwise I'll just eyeball it and program a close approximation.

...oh, and yes, I am aware the roudns will need to be of a small diameter to fit in my 37mm launcher.

It doesn't really have a lot of dimensions, but it does list a bunch of 40mm rounds with pics.  www.fas.org/man/dod-101/sys/land/40.htm

Might give you an idea of the general shape and coloring.....

That should work fine.  I can use the length measurement and known width of the casing to scale the illustrations in AutoCAD and then trace them to a close approximation.

Thanks!

Grog over at 37mm.com sells resin duplicates of crap tons of different 40mm rounds for displays.  Those would be what you should get your hands on.

He doesn't make 37mm replicas of 40mm rounds, and this actually is for a CNC calss fora  project, so his resin shells aren't going to help me get a grade.

However, I may be able to ask him for some dimensions!
