Tim, I have the TS 2424 and a Delta tenon jig. (??-183). I did narrow the bar down about .010 to fit the miter slot, but I'm not sure why you think the jig is unusable???? The miter bar can be moved to an alternate set of holes to accomodate a left tilt saw. I have not had any trouble using mine. One of the new features of the model 183 was the ability to use it with a left tilt. Maybe I didn't understand your post?
