Titanium BST sprocket drive pins
These are titanium BST sprocket drive pins for an Aprilia, they’ll be raced in America. Twiddly things to make, i had to make a holder to hold when cutting the second thread as there isn’t enough plain section in the middle to hold on to, so it made them a bit more involved and nerve wracking to produce. I’m not a big fan of holders, they have a tendency to move when you don’t want them to, i prefer to hold onto the job itself if i can.
