if only the gear racks weren't so hard to come across!

Indeed. They're fairly affordable on Bricklink, though: http://www.bricklink.com/search.asp?colorID=86&itemID=697

The gear racks were quite common on the early Technic cars with steering.

It seems from your question that you want to convert a continuous circular motion from the motor into an up and down motion with a range of 5cm - is that correct?

# Pattern for vertical motion using LEGO Technic

(Asked by: username_0 on 2013-07-23)

I have a motor and some other components that move a machine vertically on the ground. Inside the machine I need to raise a part by 5 cm, up and down.

Are there some common patterns that can move objects vertically (lift) using LEGO Technic? Torque comes from a motor powering gears.

This is a mechanism that converts circular motion into [reciprocating motion](http://en.wikipedia.org/wiki/Reciprocating_motion). You may need to alter the design for your needs regarding height difference, stability etc.
