Design Question
(OP)
I'm trying to figure a way to propel/drive a drawer; similar to a cash register that rides on slides a total of 4.5" with a weight of 5 lbs. The application requires both vertical and horizontal configuration. Currently I'm using a compression spring configured behind the drawer, but find that the rate is to much in the horizontal application. Is there a way to make the rate consent in both positions ie vertical and horizontal using some kind of gearing or possibly a different form of drive device?

Also, look inside a stapler. Usually they have long springs with nesting coils.

Do you see a possibility were I can attach a threaded rod through the spring attached to the drawer with variable treading. More closely spaced treads at top and further spaced threads at the bottom correlating to the rate to the spring. The closely spaced threads will create drag on the force of the spring while the further spaced threads would create less drag allow the spring to extend to it full deflection.

I'm not sure they're produced in a size that's large enough for you, but maybe you can dissect a few and scale them up.
