Anybody has an Ikea Rothult deadbolt? I’m thinking of getting one and repurposing it to turn a somewhat stiff springlock’s thumbturn. Only I have a feeling the motor in that thing is rather weak, since it’s not mean to pull or push anything. And the plastic gears in the reduction geartrain look rather easy to strip.
If you have one, can you give me an idea of the force the deadbolt can exert?
