Can anyone tell if they have ever removed the anti-backlash nut from a jessem router Mast-R-Lift table. Mine is stripped and I’m trying to remove it. Called Jessem but they have not returned my calls. Email them and they referred me to a later model Mast-R-Lift. Which was no help it is configured different then my model. Enclosed is a picture of the one I haveIMG_4197.jpg
