[RVRC] Additional hamfest Club Construction Project

[Bryan D. Boyle]

$10?  these are not that hard to make.  longest time thing is trimming the braid to the right length and not forgetting to put the shrink tubing on.  

i make up jumpers just to relax after work.  yeah, i have strange ways to relax...but paul, scott kb2ear, or some other folks can attest to the end result...:). happy to train if anyone is interested...i do it while watching tv...:)
