Non backdrivable drill transmission

[bs7280]

Hello all,

We are trying to find a non backdrivable drill transmition/gearbox that we can modify or comes with a way to use a pneumatic piston. I have been able to find some winches and gearboxes that are not backdrivable and gearboxes that have a dog gear/clutch, but nothing that has both. I have had very little luck researching drill transmitions and think that could be a good option, especially after seeing the team 1114 2008 robot.
