Good hint Brian
    I have cut a lot of Copper Clad circuit board
VIA just turning the blade around so the cuting
is done a lot smoother, this is with just a regular
old wood cutting blade.  Have not tried alunimum
but is it is not too heavey,  Will try it one of these
days but will archive this note for reminding me
about your A-T blade...
Thanks
Bill
