Hello,
Well, I think the hand grenade is about done. Thanks very much to Kenneth for
coming up with a method to make the bumps on the body of the grenade. Prior to
his suggestion I was befuddled. It's not perfect, but looks pretty good in the
intended scene.
Regards,
Dave Blandston

Cool! This looks VERY good. I was *hoping* you'd stick with the M2 grenade.
:-) (BTW, I kept playing around with the code example I posted for ya, and
couldn't get it to look as nice as what you've done.) I also like the slight
curve where the 'conical' shape meets the 'pineapple' shape. Again, nicely done.
I was wondering about the 'pin' (the ring) that needs to be pulled to activate
the grenade...specifically the 'clevis pin' part that sticks out the other side
(to hold the ring until it's pulled.) The two tangs, bent as they are at almost
right angles, would seem to make it difficult to actually PULL the pin. Looks
like the poor soldier would have to exert a *lot* of force to bend those, to get
them to go through the hole. Or maybe I need to look at the reference photo you
posted awhile back...

Thank you for the compliments! I almost gave up on the pineapple shape but the
plain round grenade looked pretty boring in my scene. The Mk2 is much more
interesting.
I've pulled the pins on a few training grenades (one every year, to be exact...)
and yes they do require some effort, but not excessive. According to the
Wikipedia entry, the rings had a tendency to catch on brush in Vietnam and cause
unintentional explosions.
Thanks again for helping me with the bumps. I'd be happy to post the final code
if you're interested.
Regards,
Dave Blandston

As a non-military man I always wondered what would happen in the following
situation:
You pull the pin and release the trigger for a second. Will pressing the
trigger again stop the detonation or, once released, will it explode?
Just an idle thought I had when watching a certain brand of movies...
certainly not something anybody should try out. ;-)

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.
