Dave (or others interested):

        I purchased both 1/4" and 3/8" tubing from Whitson and Co., 840 Ave. F,
Suite 103, Plano, TX. ph. 214-423-5255.  The specs are "TECH 50" which refers
to the electo-polishing of the inside.  For 1/4" O.D.the part # is: 50-xx-250-
035.  Also, if and when you order tell them it is ok to cut it into smaller
lengths.  When I ordered a 40 ft. piece they had to get a semi trailer to ship
it and charged extra!
