Wow. We are upgrading to thicker tubing, but not THAT thick. I guess there's no harm though using thicker stuff, might as well.

Tell us how it goes!

I see you've discovered speargun tubing.

We picked up some after a recommendation and found the results to be pretty impressive compared to your usual surgical tubing. Amazon has a nice selection in a wide variety of lengths.

At that point, why not simply go for solid? Though then its not technically tubing....

Looks like a nice upgrade to our current black surgical tubing.
Instead of knocking the lights out, we could shoot a hole through the roof.

LOL. Yeah this is 19mm diam "tube" for a spear gun. Good news is that it is simple to use seeing as you don't have to tie it off you can use the inserts specifically made for spear guns. In our case, we can now wind thin diameter spear gun rope around a drum instead of the entire tubing to make the shooter variable.

It's pretty much a rubber rod. My team has a roll of it, too.

Bummer...we thought we were the only ones using speargun tubing.

Re: pic: This should do the trick

We just finished prototyping our linear rail gun shooter in PIC below.
It uses two lengths of not quite as big, tubing (one on each side) to power our ram.

The hole in middle is useful for end inserts to to anchor tubing and transition to end elements. The extreme wall thickness makes it hard to prevent inserts from slipping out. We ended up having to add a nylon insert nut to our threaded H/W ends to prevent H/W from slipping out past hose clamp at extreme (3X) extension levels.
