I have a question, will the TS75 ride on the HK Track? wondering whether to purchase both saws or just the ts75 and add the hk track for quick crosscutting.
No -- the HK tracks are specifically designed only to work with the HK saws. There is an additional track in the center that prevents the normal tracksaws from fitting, not to mention the latch mechanism on the side that locks the saws to the track.
