Tamiya Universal Arm Set 70143

The Tamiya 70143 Universal Arm Set can be used to create crank systems, link systems, and structures for your robot or other project, as illustrated at the bottom of the instructions shown here.

This set includes four 33-hole arms with 3 mm holes spaced 5 mm apart. The arms can be cut to the desired length (each arm has regularly-spaced grooves that help to make a straight cut), and the holes can be modified to create longer slots for use in a cranking system. Four L-shaped brackets are included in the set for mounting axles or for use as structural support. Also included are twelve spacers at 5 mm, 10 mm, and 15 mm lengths, eight plastic nuts, and a metal screw and nut set.
