ELBO - articulated hollowing tool (Rating: 4)

I just set up this new tool and hollowed this piece of firewood( 8×5w ) to 6 inches. Very easy to use. (I have hollowed by hand, so I do know how) Anyone who has a modest amount of turning experience will find it relatively easy to do. I got this from Packard Woodworks and I believe it is the least expensive on the market at this time.
The bad? One of the grub screws was already stripped before I even put it together. One of the long bolts that clamp the holder on the quill, was shaped like a horseshoe. What the heck? How does that get thru a manufacturer's check while packing?
Other than those 2 things this works very smoothly and makes arm & shoulder battering hand hollowing a thing of the past.
