But if I buy the Grizzly, I'll probably make my own free standing tool rest and see how that works before I go through the expense of a commercial one. Still, I'd be interested to know if anyone does mount the PM extension to the Grizzly. Or any similar sized Grizzly for that matter.

As much as I'd love to have an AB or even a Liberty, I just can't justify that kind of money on a hobby lathe.

I found that the extension on the Poermatic tended to vibrate when turning large pieces. I used my hydraulic table under it for support. I suspect the Robust machines would also have problems when the extension is unsupported to the side like the Sweet Sixteen?
