Re: [TCML] connecting tubes to make primary
James-I have spliced many copper tubes to make a longer primary without a problem. But don't use tape! The adhesive is non-conductive to begin with, then the tubes will arc from the ends and burn the tape off. Last thing you want is a loose piece of foil floating around the primary!
I have gotten the best results using small diameter tube in 2 ways. One way is to machine a very thin wall sleeve to splice over the OD, ad then either crimp it slightly, or use a couple tiny set screws at 90 degrees off the plane of the primary, facing away from the secondary. Try to make them flush as possible. The second way is where I made some plugs to fit snugly inside the tube, and then put a slight crimp or ding to secure it. Make sure the tube is cut with a saw at the ends you want to connect, as a tubing cutter will compress the ends in, and not allow the plug to fit.
I have seen some manufactured copper 1/4" sweat fit couplings in the past used on some refrigeraton systems that would probably work great too, but I could never find them in a size smaller that 3/8 inch. So I don't know if they are still made any more. But if you can find some, that would be the easiest way to go.

Subject: [TCML] connecting tubes to make primary
Hello. I have two packages of 25ft flexible 1/4 inch copper tubing.
Is it wise to connect them together with aluminum tape to make the 50 feet of tubing that I need for my primary?
Are connections ok to have in a primary coil? Or should the wire be constant.
Thanks!
