What is the problem with the tool tip replacement? Is it just the problem of 
the tip wearing down and having to be constantly replaced and shaped? or is 
the problem more complex?
I toyed with the idea of a home-brew STM not that long ago. I built a piezo 
scanning head in a few hours and then became distracted by a more interesting 
project. I have thought about continuing the STM construction and had a few 
ideas about tool and scanning head refinements. 
Maybe this thread is just the incentive I need to get the project off the 
shelf.
