Thanks for the input Colin, but none of those 'High Priced Spread" models have the table travel of the go704. As for the spindle speed I generally agree, however I have managed to do some nice work with some decent sized carbide bits in my micromill, they just need to be sharp, and feed rates that make fine dust seems to work well. If it burns, get out the dremel and a diamond wheel and sharpen on the face. If truly sharp, no burns. > On Thu, Feb 24, 2011 at 2:25 PM, gene heskett <ghesk...@wdtv.com> wrote: > > On Thursday, February 24, 2011 02:07:22 pm Colin K did opine: > > > $5k sounds like a good guess.
