Homebrew PCBs

I wouldn't consider the tools using the flexible shaft as a stronger
alternative than the main unit.  The 'bearing' mechanism (it could be brass
bushings) in the pen attachment is even more fragile than the one inside the
main unit.

The shaft is a very fragile thing if you abuse it.  As long as you respect
the minimum bending limit, they are ok.  But the pen is better suited to do
extra fine work.

The shaft will flex under load and most likely snap at some point.  The best
setup to use the shaft tool is to suspend the main unit from the ceiling.
Set it at a confortable height where you can easily work with the pen, kinda
like the IV bag and pole they use in hospitals.

I may be tempted to get a flexible drive shaft and use that with the cutter,
if only to save putting too much stress on the bearings in the tool.
