    Bought an actuator kit from makerstore in australia and I'm having trouble getting the bearings and lock collars on 8mm acme lead screws.

    Any tips?

    Thanks,
    Alex.

    Using some emery paper lightly sand the ends up to about 20mm. I usually put the lead screw in a drill and hold the emery paper around the screw. A light sand is enough to allow the bearings to slide on.

    Yep, 8mm inside an 8mm would be a chore to smash in so 220 grit sand paper works as well and I like the idea of putting it into a drill that way it doesn't get more sanding in a spot to cause a side.
