 There are times when your team will struggle and there are times when it will achieve great victories. There will be times when unknown and uncontrollable factors will intercede to provide an unexpected outcome for which your team must compensate. - Travis Hoffman [more] |

Re: Supporting 40lbs Arm with Motor?
The elastic is a good idea and the simplest. You could also drive the arm with a screw. It will give you your mechanical advantage with out back driving. Use a Love Joy between your screw and gearbox output shaft.
