Wands are 1/4 or 3/8 pipe thread. If you want to thread your own, you will need a set of dies, a wrench to hold the die while you thread, a vise to hold the pipe, and cutting oil. I use only Ridgid brand pipe wrenches, cutters, handles, heads and dies. I estimate you will have $150.00 to cut 1/4 and 3/8 threads. Or you can go to the hardware store, and buy just the dies and use an adjustable wrench to cut your threads. Why not buy the wands ready made, and insulated?
