I'm using the 1/4" saddle valve for my flanged cartos. Got it from Lowes in the Plumbing section. I think I paid about $6.95 for it and it works just beautifully..... Using it mainly to punch a second hole in my 1-hole cartos.... Works just fine.
Say err, I just ordered a dct and some pre-punched cartos why are you folks drilling your own holes when they make pre-punched ones?
And crispy critter how are you making the hole in the plastice ce2 tubes?
I'm not even sure the newer thicker plastic CE2's would fit in a tank but slotting them with a dremel would be easy as pie even on a slow setting..I use cutoff wheels. Even the stainless tubed XL CE2's I use the cutoff wheel goes through it almost like a butter knife through butter.
Another option with CE2's is you can just cutout most of the center of the tubes just leaving enough at the bottom to go into the tank and a piece at the top just long enough to go through the tank into the rubber cup of the CE2
That just sounds brilliant right there. I'm gonna give it a try.
Interesting aside to this, I went to my local harbor freight tools over the weekend, looking for both a dremmel tool and a saddle valve. The guy who was helping me was asking me "ok well what are you trying to accomplish" so I started tell him, showing him my equipment and he went totally crazy. He was like "WHAT??? THAT THING IS AMAZING WHERE CAN I GET ONE? It keeps you off cigarettes? they have different flavors?"
I half wanted to invite him over for a beer to see my collection of stuff, but I didn't. I just sent him to my vapor store for a starter kit lol.
I think I will head over to harbor freight in search of a dremel tool then. I like the idea of using a ce2 rather than a polyfill carto in the tank though I've not tried the tanks yet but just ordered one. So slow speed will make a decent hole? I've got a bunch of old tubes laying around, guess I will practice. I would think using a ce2 would largely do away with the need to prime a carto.
Where are you putting the hole in the tube?
