[TenTec] The problem with directly end fed wires

Does anyone have a stock or source for small amounts of 12 guage tinned solid wire for "rolling your own" tank tuner coil OR does anyone have some spare 2.5 inch diameter, 6 turns per inch stock they would part with?   I have a very effective homebrew balanced tank tuner which uses 14ga by 41 strand SIS switchboard wire over 2" PVC conduit form.   The design was based on a tuner appearing in the 1955 ARRL handbook.  With ganged 500pF EFJ caps with isolated stators and/or rotors, it orig tuned 80,40,30 with one coil very nicely.  After moving and putting up a CFD with a much shorter feedline, it now requires changing the coil and link to go from 80 to 40M.  A real pia.  I would like to make the coil from bare wire to make taps for jumpers rather than have to change out the coil when changing bands.    
Thanks,
Mike, AC5P
