Greetings all;

Does anyone here have a Grizzly GO704?  I feel the need of a bigger working 
envelope than my micromill with its expanded table kit gives me.  That 
would expand my Y motion a good 2", the X at least 8" more, rather welcome 
when carving bigger pieces of wood.

I have some concerns about the Z axis drive, and am wondering if I'd have 
to build another overhead like I did for the micromill before I could even 
think of drilling a hole using EMC.  Looking at the manual pdf, I don't 
care for the non-adjustable nut, nor its floating socket in the back of the 
heads sled, and an apparent complete non-adjustment of the mesh of the 
bevel gears that drive it. That looks like a combined backlash in excess of 
.050" to me.

If anyone has one of these, pipe up please and relate its major gotcha's.  
At about $1400 (plus another 2 bills to get me to the store & back to pick 
it up, by the time some tooling is included, it has to have a major weak 
spot someplace besides its puny little 750 watt motor & 2 speed gear box.

If I had to, I could do a better job of making another column riser to 
support a drive similar to whats on my micromill, which took the available 
down pressure I could put on a drill bit from 4 to 6 pounds up to 155 
pounds.  That actually made that little mill usable, within its motion 
envelope if the cut depth was miniscule (also hard on bits, the light cut = 
high wear even on carbide)

Cheers, Gene
