Works OK after some fiddling
I got the 59‚€ and 46‚€ tracks and a connector bar, and connecting the two lengths works for ripping 8‚€™ sheets of plywood. It works, but only after some tedious adjustment. Once they‚€™re connected, the tracks stay in alignment (assuming you don‚€™t bang them around). You have to trim the rubber slitter guard at the ends of the adjoining tracks, and even then, the tracks aren‚€™t perfectly matched, so you have to use an accurate straight edge across the joint between tracks, and then adjust the connector rod. That rod goes in the back of the tracks, making it hit-or-miss to get the tracks into perfect alignment. It‚€™s possible to drill and tap the ‚€œup‚€ side of the tracks and use 7/64‚€ set screws, which would make it much easier to align two tracks. The alignment rod is secured by four set screws that require a 3mm Allen wrench (not supplied). A 7/64 will work but be a bit loose in the screw heads, bringing the risk of rounding them off with repeated use. If you frequently rip plywood lengthwise, buy the 105‚€ track which is available as an accessory.
ProsSecure connection between two tracks
ConsDesign makes it tedious to align the tracks; tightening the connector requires a 3mm Allen wrench which is not supplied with the connector rod.
