Re: [CAD_CAM_EDM_DRO] CNC Router Head/Motor???

I must not have explained myself very well as usual. I'm not looking to
cut 6" with a .25 diameter tool. I'm looking to cut 6" with ??? tool? I am
asking what type of machine head can I buy that will allow me to cut at
depths of 6~8" like see at this site
http://www.corpcomp.com/weeks1/mb/mb.html Looks like I will need some type
of mill had or something with a morse taper or r8 Spindle that will allow me
to chuck a bigger bit. I've almost thought of using this:
http://www.harborfreight.com/cpi/ctaf/Displayitem.taf?itemnumber=37505 and
stripping it down but it doesn't have a spindle that I can work with, I
think.

Thanks
