no, not at all. I chose this setup because there must be a certain  
arm-length to approximate straight movement with a pivoting action. Also,  
in order to minimize sideways play, the bearings must be apart some  
distance. So that more or less gives a minimum size. Also, the bottom  
plate and table was one piece initially, and i only needed one cut on it.

There is now a neat space under the table for drills, and the hoover  
nozzle is fixed to the arm, as well as a small lamp. Not sure if i add the  
projection mechanism one day.
