Add Heat-Set Inserts to J0 Plate

The J0 plate requires 8 M4 heat-set inserts. 4 of these go in the bottom for the stabilization set screws. 4 go in the top to mount base J1 to J0 plate.

Add Set Screws and Nuts to J0 Plate

These set screws stabilize J0 plate against the thrust bearing. The nuts must be in place to lock the position of the set screws in a later step. The nuts go on the bottom of J0 plate.

Attach J0 Plate to the Hub

Use #6x0.5" button head screws to attach J0 plate to the hub. Apply thread locker to the screws. Make sure the set screws do not touch the thrust bearing yet.

Tighten J0 Plate Set Screws

Lightly tighten the set screws in the J0 plate to touch the thrust bearing. Overtightening will bend the J0 plate. Once the set screws are touching the thrust bearing, tighten the nuts against the J0 plate to lock the set screws in place.
