Even a single pound of weight is too much to safely throw in someones direction. This is why madbull decided against using a gas to power their hand grenade design. Any gas system will be either too heavy, or wont last in the long term.
Hockey tape wont provide protection from injury either.
You need to consider the amount of force someone is likely to throw it with in the 'heat' of battle. A plastic pipe full of powder to the head could still easily cause damage.
the hockey tape is just for testing purposes. i do agree that weight is a factor. and yes there is some metal on the inside (a washer and small copper tube that houses the Co2. also a puncture pin. the prototype is about the size of an areisol can but im sure i will be able to miniatureize future versions.
this should cut down on weight. the size of the claymore wont change as it is just right and it will speed up development to have it more than half made. it would be nice to have a limit to work within as far as weight goes. what is the maximum weight you would suggest for something such as this. keeping in mind propper use of this grenade is to be lobbed, not directly fastballed at someone. any grenade aside from the cork ones will break your face if whailed in the heat of battle. while this may eventually happen it would not be propper use under the instructions. thus limmiting liability and placing all ownace on the users head.
pvc will barely hold the Co2 pressure u need to use black ABS pipe.
i think there has got to be a compromisible weight that everybody should agree on. i am not too concerned with making a crappy ass joke grenade but i do want to keep playability in mind. the nerf look just doesnt do much for me.
