Yoke jig. Two small aluminium plates with three holes in each. Center hole is 2mm and it takes waxed SS rod that holds the jig in place. Two 1mm holes for pins. Pins are made from small nails that are sanded down to exactly right diameter for Dymond D60 horn holes in drill. Aluminium plate and center pin are waxed three times using Norpol W70. The bottom parts of the yoke pins that are inside the aluminium block are waxed too (just pushed them into candle). Over the center pin is small piece of SS tube with 2mm inner diameter. Shaft goes into this later. The tube is from even bigger syringe needle :) I wrap a yoke using single tow from uni carbon cloth. Tow is wetted first. Wrapping is very easy because the jig can rotate around the center pin. Just do not apply too much tension when wrapping! When you remove the yoke from jig the pins may wrap little bit. I wrap first around the pins (like shape of eight) and then around. the pins. Couple of drops of resin to fill the voids. Final weight was 0.7gr.
