I do the same as Denny but I also I use a worm clamp to attach the hose to the cane. I tighten it down after I squeeze out the bubbles. It may be the tubing I am using, but bubbles were reforming

I assumed everyone gets bubbles.  I think it's just the physics of the cane that air gets trapped there somehow.  Pinching it has always worked for me.

I guess I'm old fashioned...I just use a plastic racking cane and a piece of tubing.  No autosiphon, no carboy cap, no pump.  I guess if ti didn't work I'd change, but I've never had a problem using such a simple setup.  I can't imagine why I'd want to do anything more complicated.

This is exactly how I do it as well and for the exact same reasons, simple and basic and functional

Bubbles cause oxidation?

It's what I've done for 20 yrs.  I like low tech (unless it needs to be more tech).

Bubbles cause oxidation?

Yep

[klickitat jim]

If that happens I'm going to throw a full on hissing fit

[hopfenundmalz]

Bubbles cause oxidation?

Yep

I might have one bubble at the cane hose junction, a pinch gets rid of that.

A stream of bubbles is a loose fit, or a hairline crack in the plastic cane. I have had a hairline crack in a plastic cane. A SS cane fixed that.

Not every bubble in the hose is air.  If you start with a clean stream of beer, and start to develop bubbles at the junction of the racking cane and hose, or even farther down in the hose, they are probably CO2 coming out of solution due to the pressure differential going from the cane ID to the hose ID.  On the other hand if you have a steady stream of bubbles forming, it could be a crack in the cane or a too loose hose.  But even with a clamped hose on a good cane, you will get CO2.  Not to worry.

That sounds more like what I was seeing

[Jimmy K]

I have a SS racking cane. It has all the high-tech features it needs - it's round, long, and straight.

[klickitat jim]

Hmm, why not copper? Could use a tubing bender and make the bend big enough to actually fit a scrubber through. I think I'll make one.

[Joe Sr.]

I don't think you want copper in the beer once it's fermented.

[hubie]

You wouldn't want to use a copper as a racking cane.  You wouldn't see the buildup of any of the bad blue-green oxide (verdigris) on the inside of it.  Either that, or you should always assume it is there and treat it accordingly (e.g., acid clean it) before each use.

It would be a killer racking cane

Ok, scratch that bad idea.
