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.
WHAT?? ABS is NOT pressure rated! :smack: :smack: it can't handle repeated pressurization. You should never use ABS in pressurised device (like a CO2 hand grenade).

You need Sch40 or 80 PVC. Just look at what ABS is used for (Non Pressure rated Applications) so its not made to hold any pressure at all except of water under gravity. Pressure rated PVC is made to hold water pressure so it is suitable for pneumatics. Pressure rated pvc means that it has a pressure rating and "Schedule 40 or 80" printed onto the pipe.

2" PVC Schedule 40 pipe has a pressure rating of 280 PSI. Take a look at the 12gram CO2 chart, for your safety :

Take care and remember, safety first :salute: :wink:
