My lathe in the specs states it has a 14'' swing over bed & 17'' over gap. The tool rest will only let me do a object a little over 9''.....I can do something flat out to the 14'' but I can't do the edge on the bowl ......Am I doing something wrong or is that the limit of the lathe. It's a Grizzly G1495...Can i get a tool rest that will go out further....
