"THE TRADES FIRST ROUND MAGNUM JIG"
Makes rounded magnums sizes 25, 35 and 45. Will also make traditional flats and square magnums in the same sizes.
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.
