Your lathe will likely have a 4 way tool post. This is what something like 99% of all Asian (and American) machines are going to have. As for cutter size, don't buy anything until you get the machine, but chances are if it fits a AXA quick change tool post, you should be fine up to 1/2".I am getting ready to order n 8X16 metal lathe. Budget dictates that it be an Asian machine. None of the ads indicate what sized cutter bits to buy. I see 1/4", 3/8" and 5/16", as well as 8mm and 10mm. Is there a way to adjust the height of the cutter so that it meets the centerline. It looks like they index on the bottom of the bit, so they would each meet the work at a different height.
Second, I am looking at Amazon as the primary source for all of the add ons and accessories. Is there another source. I prefer to give my business to small shops, even if it costs a little more, within reason.

Last, how about suggestions on machines. I can't spend more than $1500. I know most of them are made in the same Chinese factory, but I'm told that retailers make substantial changes both good and bad. They all look similar, but.....
The other problem is power. Let's say you're cutting large diameter material where the surface speed is quite high. For once, it ought to be high enough to actually get a good surface finish with carbide. You touch the tool to the work, and it shoots out a tangle of metallic silly string. The long, unbroken chip wraps around the part and ruins the surface finish, and maybe flays the flesh from your bones too. You want to get the chip to break, you're using carbide, so have little control over tool geometry. About all you can do is increase the depth of cut to get the chips to break, and put and end to that silly string. (At least that's the only thing I know to do. I should in no way shape or form be considered any kind of expert or authority on anything.)I think the biggest problem with a larger lathe is inability to crank up the RPM to get the best surface finish for smaller diameter stock. I mean some of the carbide inserts really want at least 3000 or higher RPM for good surface finish, and no lathes in the 12-20 inch range is capable of that RPM (nor can do it safely),
