I have had a Mast-R-Lift for some time and am very happy with it -- except for the limited size choices for the insert rings. The Pinnacle insert sets at Woodcraft look nice (phenolic or aluminum), and have a lot more choices. Does anybody have any idea whether these rings will fit the Jessem table? They look close, but close doesn't count. Otherwise, maybe I will just have to buy some of the blank inserts and make my own. The Pinnacle set just looks like a nicer and cheaper solution.
Thanks
