what would you suggest is the best washer size to use. 1/2 inch? or 7/16th. id perfer em sensitive but if they explode in the hand with 1/2 i wouldnt want em. what do you reccomend?
any idea how many times you can reuse them? you should refill and deflate the nade over and over choppa and see how many it takes till it bursts
I used 7/16" for all the grenades you see in the photos and video. I will say, with 7/16" washers, the washer must be pulled very tight against the pin so only a little of the top fold in the tube is exposed past the washer once the pin is removed. I mean that washer has gotta be barely on there. Using a 1/2" washer, the grenade is more sensitive even if the washer is not pulled as tight against the pin, but having used both, I prefer the 7/16" washers for the little bit of added confidence they give me while pulling the pin. Just make sure if you use 7/16" pull the washer tight to the pin so they will go off with very little force. Check out the video. I know it's tough to see, but in the beginning you can see how little of the fold I leave sticking out of the washer. I suggest playing with several sizes and play with how tight you pull the washer against the pin. You will find the setting that is right for you.
In regards to how many times they can be reused, I would say MANY. My suggestion would be that if you find a spent tube with the intent on re-using it, just give it a quick visual inspection and make sure it is free of punctures. If it holds pressure, I say go ahead and refill it. I can tell you the first prototype grenade we made was refilled at least a dozen times and it never broke.
