Well, with thicker tubing, the outer layer will be thicker! How much thicker would it be? As I understand it, the frequency determines how deep the current flows. 73 Jim W5JO

Hi Brett; I am going to wind a pi section tank coil from 1/4 copper tubing tomorrow. Mine will be 4 in diameter and 3 in diameter. Which tubing is best (no kink) thick or thin? Thanks. 73, Ed Richards K6UUZ Simi Valley, Ca 93065 Home of the Air Force 1 pavilion On Sun, 08 Jan 2006 18:48:57 -0500 Brett gazdzinski [EMAIL PROTECTED] writes: If it does not need to be real small, one way to get a good coil is to wind one out of copper tubing. Home depot sells various types, small/thin, bigger and thicker... I made the pi net tank coil for the pair of 4D32 rf deck out of copper tubing, I soldered big wire terminal lugs (the crimp on type) on the ends of the coil and bolted it to large ceramic standoff insulators. Here is a link to a picture: http://wa5bxo.shacknet.nu/N2DTS/new%20coil-a.JPG My thanks to wa5bxo who still has my pictures up! The wine bottle in the picture was used to wind the tubing on. The home brew receivers are in the background... Brett

- Original Message - From: Edward B Richards [EMAIL PROTECTED] I am going to wind a pi section tank coil from 1/4 copper tubing tomorrow. Mine will be 4 in diameter and 3 in diameter. Which tubing is best (no kink) thick or thin? Thanks. A trick to making smooth bends in soft metal tubing, is to fill it with fine sand first. Now - I understand this can be tedious with long lengths of small-diameter stock, but if you have no other mandrels or fixtures to wind it on, sometimes this can help from developing a kink in the pipe. Then, you can blow the sand out, or just leave it in there - won't hurt the electrical specs of the coil... Cheers John KB6SCO
