I have two latex tubes, I want the one inside the other. Latex is extremly flexable.

I tried fixing a string to one, putting the string inside the other, coating the tube with the string attached in grease and pulling it through put that didn't work. Any ideas how I can do it? These are for my paintball grenades, I need the new ones to be extra tough.

There is a pic of the tube below.

For paint grenades, you don't need to double layer them. I just use 1/4" ID rubber/latex tubing with 5/16" ball bearings and they don't pop when they hit the ground. They should be fine with only one layer. It's going to be really hard to fill them though.

Yes, I have the same latex tube. It is really simple to fill them, I made a pressure vessal for injecting liquid at a pressure, let me show you one of my banana bombs. I am developing my own version of the big boy grenade, just with a different trigger system. I want to sell them at my home field in the holidays (December). I did manage to sleeve it once, only a small piece but now I have a double layer latex tube with an aliminium pipe stuck inside. Oh well, at least it is fun to bounce off walls

could you somehow role one up like a donut (inside out sorta.)

Those are pretty nice, mine don't have fancy safety pins. I can use them in my nade launcher without doing anything to it first though. I just keep the launcher loaded and pressurized so if I see a group, I can shoot fast without having to waste time pulling a pin and throwing/launching.

I would thing you need special tools to apply foce in all the right places in order to do things like roll tube. I can't use these in small launchers becasue they are curved, I think because the tube came rolled up, and they are quite large. I have given up trying to sleeve tube for numerous reasons, I am going to experiment more later today.

JEEZ! With the size comparison, that thing is enormous!

Hence the term banana bomb

This one worked well, I added a double fold to the top to see if it helped, there was no difference. I managed to sleeve the first 1'' of the grenade, it is only 5'' long anyway. I wanted to see when it would burst, it didn't and it was huge! I put the extra tube on the end so it wouldn't expand there and folded it closed like normal. It popped on contact with the ground, the ring didn't even pop off. It had split all the way down the length. It was so big you could fit three hands on it.

maby force air into it while putying a dowle inside it, then just roll it up

It probably burst because of how big that thing was. If one of those three-handers did work, it would be spraying for at least 3 seconds!

I don't need to sleeve latex tube anymore, I found that it does not preform that well.

The normal ones spray for about three secons. That is with water, I havn't tested paint yet. I am trying to get the realese mechanism more constant, that is the only thing that matters.
