I had previously built my tenoning jig for my other table saws fence with scrap plywood (I tend to build a lot of jigs out of left overs) and it worked fairly well. It consisted of nothing more than a few pieces of plywood which slid along my table saws rip fence.
My new tenoning jig is made by the same company that made my table saw (although probably not in the same factory). The new one is a lot more “heavy-duty” and has more adjustability. Like my mortising machine mentioned in mortise and tenon #1, I had previously put it together and then set it aside, waiting on the opportunity to use it.
