I build a Langolits unit and used 1/4" OD copper tubing on the base,
and a tee so I could pump water into that tube.

Since I used compression fittings, I just made a section and soldered
some brass tubing to that. very simple. the hobby shop sells 3 foot
brass tubing for about $4.00 or one foot sections for about $1.50

They carry 1/16 and 3/32 so that is pretty easy. I can get 1/4" hard
copper at the refrigerator supply house. Makes that pretty easy as well.

I bought a Ralmikes Spark Eroder, but never could find any information
on how to use it. Still using my home brew version.
