... Some years ago, the Velocity factory recommended an automatic lock be used, similar to the passenger side door. I didn’t like the design because it took two hands to open the door; not exactly what I’d want in an emergency. I thought my double spring over-center linkage on the latch was the better way; and maybe was. I don’t know, but I have to leave open the possibility that I had not fully engaged the latch.


Al,

Given the critical nature of the latch in this application, I
wonder if a "bank vault" latch might not be a good idea.

Attached is a simplified illustration of the concept. A latching
handle could be constructed with a release similar to that of a
console-mounted auto transmission shifter, for one-handed
operation.
