One note. copper and steel fittings should be seperated by brass, or some other metal. The copper and steel corrode. Remedy that with a gatorbite brand fitting for your pipes if need be.

Well i was wondering about that, i had heard about this before years ago but i wasn't sure how much of a roll the teflon tape would play, i put a generous amount on and hoped it would prevent any issues.. any thoughts?

You will not get much if any reaction between the different metal types touching. Generally, noticiable reactions will happen only when the metals stay wet or in contact with corrosive liquids.

It didn't take but 5 brews in and sure enough, the copper and steel were corroding and rusting. I used generous amounts of teflon tape as well (3-4 revolutions.) A friend of mine alerted me to this metallurgic terminology and it sounded right. He was definitely right. I switched it out and made sure these two did not connect again. wort is acidic, hence it will hasten corroding of the metals copper and steel which are placed together. no amount of tape will prevent them from touching.

check out galvanic corrosion

Brewed a Black IPA this weekend with the new keg MLT / Boil kettle and the tested the two new dip tubes. They worked great and maintained the siphon until there was only an ounce or two of fluid left. The total cost to build was about 6$ so i would chalk it up to a win.

What I did is slipped my pieces together and with a center punch put one dimple at the joint. Keeps the fitting snug but still removable.

Just don't do any extended soaks and you should be fine.

Main thing is to rinse well after cleaning to flush away the flux

Why do you mention not doing any extended soaks with the oxyclean (etc.) Curious as I haven't come accross that before and I let my immersion chiller soak for a little while sometimes to remove oxidation before using it.

I use fine steel wool clean up copper pipes that have discolored from heat. you might want to 'pickle' the brass union.

Aside from lead solder is there any good way to join the pipe to make this option work? Any thoughts??
did you buy that false bottom or make it?
