Alignment of the cams
After assembly some one or both of the cams might turn out to be not parallel to each other and not running smoothly on the cord. If that is your case just heat one side of the affected arm of the bow and twist it until parallel. It will be well visible on the "string". Let is set by cooling down. Voila!
Tension the strings and cut the ends with hot soldering iron and tie when everything aligns well.
For the "bearings" of the cams I just 3D printed small barrel like washers fitting sides of the cam or use real bearings.
