A base-plate pin incorporates swivel functionality; the lower mast section rests upon it. Upcoming visuals will depict its structure. Note: This component hasn't undergone stress testing yet. Exercise caution when using untested parts. After further tests, this warning may be removed, but exercise extreme precaution during mast setup. Remember that the origin isn't at the part's bottom when installing it.
