Adjustment doesn't necessarily mean "turn a screw to adjust". It can be just a plan of attack on how to tweak things when you get down to your final configuration/implementation.

For our 2011 elevator, we used Teflon pads on the outside of the 1st inner stage of our lift (http://www.chiefdelphi.com/media/img...e4ed3dc_l.jpg). You can see the white little skids on either side up near the top of the elevator.

Knowing these were going to be our primary mechanism to eat up the tolerance stack up from the welding of all the assemblies and machining of the necessary brackets, we knew we were going to rivet these things on with countersunk rivets and shim stock behind them. The shim stock was the adjustment for the side to side slop. We only needed to tune it once on our final assembly and we were set for the year.


Just an example of how you can build adjustment into a design with part of your assembly. It doesn't need to be as elegant as bolt adjustments and the like, but of course pulling those off can be cool as well.
