Re: Are Firgelli linear actuators legal?

Our team has successfully swapped the stock motor on this: https://www.servocity.com/html/25_lb...l#.VrEBX7IrKUk

It's very similar to the firgelli ones by the look of it. We used a vex bag motor and it seems to have ample power. The hardest part is coupling the nylon pinion gear to the bag motor shaft, if you have a good machinist, it's doable though. As stated above, the in-line limit switches have to either be disconnected altogether or wired up to the roborio to be legal. At this point our team has just disconnected them because they weren't working as we had though they would.

I'll try to get some photos of the inside of this in the next day or two.

Also, when we got the actuator working with the new motor, the in line limit switches weren't connected (obviously) so we accidentally stripped out the nylon pinion gear, (I'm not sure what sort of pinion gear the firgelli ones use) Servo City customer support has been very helpful in ordering replacement pinion gears. Just be aware when you guys are messing with these actuators not to damage the pinion gears like we did, or anything else for that matter.

Sorry for not having more specific details or photos at the moment. I'll try to update with more info soon.
