Liner Needle Jig
A simple plastic jig that is used to hold your needles in a basic round formation while you tack the ends. Gouping holes are 3, 5, 7 &14 based on #12 needles. You can use bug pins but obviously you can fit more #10 or #8 bug pins in a hole than you can #12's.
DISCLAIMER: These jigs are for getting needle groupings tacked together in proper formation. All other soldering needs to be done off of the jigs. I always thought that this was obvious and did not need to be said but these are made of plastic and will melt when exposed to extreme heat.
