I came across an easy way of making prickers out of Tilley prickers. Using 2 diamond dust sharpeners held lightly I was able to have a lot of feel and control. Cutting wire over length means the flex of the wire counters any bends and lets you hold it all central. The straighter the wire the better but does note have to be absolutely straight. I used the dremel to grind off the bulk of material first with drill spinning to keep everything round. The rubber band on the bottom did help. Had to wrap paper around wire so drill chuck was able to hold. The second one took no longer than 7 minutes.
Well done there Anthony. Another way. I just use the green wheel on grinder using my magnifier glasses plus you need a steady hand . Bob .
