Quick and easy swivel seat lock

[SimonM]

As I had a spare motorbike disc lock lying around I simply drilled a hole in the base unit to allow the hardened steel shaft to go through. The lock goes on the other end inside to lock it in place.

Now the seat can be locked 180 degrees to the steering wheel to visibly deter a casual thief. I’ll keep the key hidden away from the MH keys.
