unfortunately no, I have the 4003 G and there's really no easy way I'm aware of. I ended up just building a CNC lathe based on the same design the cueman lathe is based on. Then I just got a ball bearing 3 jaw chuck on its own mount. That let's me do the work I need to that needs perfect centers.
That also gives me less distance between the chucks than having a rear chuck on the grizzly would give you, allowing you to do work with smaller pieces, like say, JUST a forearm...
