Or maybe these tracks and t-bolts are too roughly machined and better ones are available.
Or should I try 1/4-20 t-bolts instead of the 5/16-18 ones. The track specified above has the multi-level inner profile (I don't know what that's actually called) so I'm wondering if I should have used a t-track with a simpler rectangular profile (if that's even available). I'm wondering if I just chose the wrong t-track. It repeatedly hangs up as I move it and fine adjustments are just about impossible. For quickersetups than a separate T-slot nut and stud,slide these bolts into T-slot tracks on machine tool tables. My issue is that the stop block will not slide smoothly in the t-track. This t slot hardware is designed with a larger head that fits t-slotted miter slots intended to help with a variety of woodworking and metalworking applications for fixturing, holding and positioning work material. I used a rectangular piece of poplar for a stop-block, secured with a star-knob. The t-track I used is and the t-bolts are. For quicker setups than a separate T-slot nut and stud, slide these bolts into T-slot tracks on machine tool tables. I included a t-track so I could use an adjustable stop block. Recently a I upgraded my miter saw stand (just an old cabinet) by adding fold-down wings. Despite decades of woodworking, I've hardly ever used t-track.
