Hello, I received 3 pieces of t-track as a gift. I am trying to build a jig but I cannot find good hardware for it. T-bolt sold by the the same mfg are too wobbly and I would like something that fits and slides better. I was thinking about a double tee nuts or a drop in t-nuts. I have attached the drawing of the t-track. Any suggestion? It looks like it is a quite nice t-track but...with some issue to be compatible with hardware. I am also looking for a plate to connect a long 36" track with 2 perpendicular 24" track pieces. While the 36" will bbe sliding perpendicular to the two arms. All flat and not standing up.
