RE: [TCML] primary voltage

Strange here too. I can get it in 50 or 100 ft lengths at home Depot.
Another source is your local auto parts store, NAPA in my case, or a shop that does refrigeration and AC, they use that size by the mile. 
I actually find NAPA to be cheaper.

Copper has shot up the past 2 yrs and is at a ridiculous price these days.
As for bending tubing, it is easy too. If you are winding a cylindrical coil, find a piece of tubing, usually a piece of sonotube will work, that is smaller in dia than you need, wind the tubing tight around it. When you release the tubing, it will "unwrap" a little to a large dia so you want your form to be smaller in dia that the finished dia. I even bought some nice 1/8" OD tubing from NAPA for small coils. This is used for the oil pressure gauges, usually they have to bring it in and it typically takes a day if the local store does not stock it.

Or check with customer service in each store... they can usually special order it for you. 
Or order it on-line from either store's website.
