I will have to go out to the shop and check... I went from the 3520 to the Beauty a while back. I always use the McNaughton, but have the Oneway for demonstration purposes. The Oneway system is made for their big lathe, which has a 24 inch throw, so moving up to 25 inches should be no problem, only 1/2 inch more, unless you have the posts for the 16 inch lathes. They are way too short.
