I have the rotary actuator built and the gripper is well under way. The way it works is, the rotary actuator shaft turns a shaft to open and close the fingers on the gripper (hand) The hand also free wheels on the same shaft so it can rotate 360 degrees continuously. So I need a gear about 2 .5 inches in diameter and a matching gear about .5 inches or less to drive the main gear. The gear set will be driven by a second rotary actuator with a drive shaft enclosed in the arm member.</div><div>Any leads would be great.</div><div>Hank</div></div></div></blockquote><blockquote type="cite"><div><span>_______________________________________________</span><br><span>Personal_Submersibles mailing list</span><br><span><a href="mailto:Personal_Submersibles@psubs.org">Personal_Submersibles@psubs.org</a></span><br><span><a href="http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles">http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles</a></span><br></div></blockquote></div></body></html>
