Double bladed sink tube question

[Nerdicus]

If I was trying to make a sink tube saber and (theoretically) I wanted to make it double bladed, could I/how would I be able to connect two of those screw on nut things like on the end of the 1.25 dia. sink tubes:

I'm mainly asking so I know whether this is possible for a later build, I'm not planning anything like this now

Large flat washers and a bolt with a nut. Or use a coupler made to do that. look in the plumbing section of your local hardware store.

Thanks again Jay-Gon. Somehow I always seem to run into you when I'm researching this stuff :P

Well, he does make some of the best sinktube sabers in our hobby.

That is what I like to call an understatement :P
