Re: Beginning User

I use a "cyclone" type precontainer (actually just a lid and a
trashcan)so it will be easy to segregate metal and wood. I cut mostly
aluminum and the shavings seem pretty light. The system is a high
volume with relatively slow velocity system so I might take a chance
and use it with the mill. Hopefully the abrasiveness of the aluminum
won't be too big a problem. I'm sure I'll find out in the course of
time - but its worth it to me to evacuate the shavings from getting
in the ways of the machine.
