Well this Jessem lift is in a Kreg table and I can now honestly say that the Kreg method of leveling the router plate is a better solution than what Jessem have decided to use. Jessem use grub screws in the plate, Kreg use adjusters in corner mounting supports which need to be adjusted from below the table. If you had a Jessem top or machined the apperture yourself to a precise depth then maybe the problem could be avoided because you would not require to use the adjusters but for other setups like Kreg then as I have said before the Jessem mounting kit would have been the better option had it been available. My issue now is that it takes some time to level the plate but after a few days it has moved, not much but enough to prevent the workpiece moving smoothly past the cutter and so more time to re adjust. Cannot see where this movement is occuring but has anyone else had similar experiences with leveling a Jessem lifter?
