I can't seem to find the mill I bought at accumotion anymore. The Sherline I got has 9" X and 6" Y travel and is 3000 max RPM. I do not see it there anymore. The one I linked is only 8"X and 4" Y and only 2,800RPM. :shrug:
Maybe they had troubles with the bigger table. Well whatever. I have to agree that the Grizzly does have a stouter backbone on the Z. But the tables are not good IMO. But I only seen the one. Maybe it was not a good one. You could easily feel the play when you grab the table. And the hand wheels, well we won't get into that.
We have a Harbor Freight locally and last time I checked their mills out non of them had good tables either. Even after messing my table up it still has less slop then the one's I seen at Harbor frieght. maybe i just got lucky to get a tight table with my Sherline. It was real nice up untill I broke a flute on a 3/8" carbide endmill by accidentally setting the Z to drill to fast. Full speed 3/8" end mill into Copper is a bad thing! After that I got some slop in the X axis. It is about .015 worth of slop now.
un-noticable on most things but deeper channeled blocks that require multiple passes show the slop a little. Shallow stuff and drilled patterns are still great though.
