Looking at the little bitty photo in the email, it appears that the T-bolt is just a T-nut with a threaded stud "permanently mounted". Does anyone know how that mounting is accomplished? The possibilities that come to mind are staking and Loctite, if the stud is a piece of fully-threaded rod. Or maybe it's a press-in stud in an unthreaded hole?

A picture of the backside is in there, maybe it can answer your question.
1951 10ER w variable speed electronic motor with reverse
1999 520 w PowerPro
Belt sander - strip sander - bandsaw - scrollsaw - jointer - overarm router - undertable router mounted on main SS saw table - speed increaser - speed reducer - forced air HEPA filter for headstock - 19" SS powered aluminum drum sander - index wheel system - lathe table crossslide vise system
I made a bunch of sliders using steel flat bar [with thinner nuts welded on to make up the depth of SS machined aluminum] (wanted the ability to use magnets on the tnuts; plus they were much cheaper to make than buy and modify SS’s) . A local friend saw them asked me to make ones with just a center tapped 3/8 - 16 hole. He had a 520 and loved making jigs for the fence. Used ready thread to make stems of custom lengths. The threaded stems allowed him to easily attach and remove those jigs. He switched from red to blue thread locker once he determined the lengths he wanted. He did paint the flatbar with Rustoleum to reduce steel - aluminum interface.
Hope that helps.
