Titanium drive pins and bearing spacers

These titanium sprocket drive pins and bearing spacer/sleeves are for a special, so special i have no idea what it is! All i know is they are going to a frame builder who is building a special for a customer. I don’t think its a secret, i just didn’t think to ask! I had all the information i needed on the drawings. But they have incredibly tight tollerences, the shoulder on the drive pins had to be 9.3mm wide + or – 0.001mm.
