I looked this up once, which means don't bet your life on it. But I 
understand that releasing the trigger starts a fuse burning inside the 
shell. Pushing the trigger back down doesn't help.

As I understand it, the moment you release the trigger enough for the 
fuse to start, there is no turning back.

It can be a fuse that burn away, a chemical that run down a porous 
material or something else. The importent thing is that once the process 
start, in can't be stopped without entirely removing the detonator 
assembly before the fuse finishes it's work: a few seconds.

The spoon is spring loaded, when you let go of it, it should go flying.
The spring lifting it also lifts a striker that ignites a slow burn
fuze, extending to the bottom of the grenade. It reaches the explosive
inside, and then it goes boom. The fuze is also never exactly three
seconds, like in the movies.

Not military myself, but I found a deactivated training grenade at a
surplus store and keep it on my desk. Startles people when they notice it.

Wow. I had to dig out a Mk2 w/ M228 training just to compare. The fuze
assembly looks perfect. All the curves are spot on.

The ridge around the neck doesn't look quite up to spec, it might cause
the frag to go off in one direction more than another, what with the
extra reenforcement. But if you add the right color markings, I don't
think anyone will notice.

Excellent jape! Just the thing to shorten meetings. I can see you, in my

That's very kind of you to notice those details. I worked really hard on the
fuze and it's great to hear a compliment.

I did cheat on the body of the grenade. I wasn't able to maintain the vertical
indented portions around the neck because the bumpy part is a height_field and
therefore hollow and can't have anything differenced from it. My original plan
was to continue the height_field all the way up to where the cone-shaped top
starts in order to maintain the indents, but that didn't work out. But like
you're suggesting, it does look good with realistic texturing.

Dave Blandston

I'm not quite sure how you modelled it, but I was under the
impression that both height_field objects (and also meshes,
which might be created for spherical versions, when closed
and using inside_vector) are solids and can be used in CSG?

Cool - it worked! Maybe now I can get that part correct. Thanks for pointing
that out.

See this is why I love these type of newsgroups.  I've been wondering about 
that for a while now but have never spent any time on it.  Now I know its 
possible it opens up a heap of new possibilities!

Passing comments like these can sometimes be priceless!

Cheers Dre
